July 25th Star Party at Mingo Observatory

The AAAP hosted another popular star party at the Mingo Creek observatory this past Friday, and I was very excited to finally take the 6SE out this darker site. I had been assembling several new accessories as well – more on those in a minute. Over the course of the night, we hosted over 100 visitors, and it was one of the best nights of conversation that I’ve had at Mingo since joining the club 2 years ago.

I set up near the reflector room, which featured the 24” Ritchey-Chrétien reflector on the new mount. The mount is amazing – solid and accurate – a true work of art. I wanted to stay close to the building so that I could work the reflector or answer questions as needed, and I wanted to be close to a power outlet :)

I set up the scope (see the photo at the right), doing a finder scope alignment and visually testing the overall collimation. I had just added some Bob’s Knobs to help me easily collimate the scope, and it appeared as though it was decently collimated at first glace. I had also purchased a new Astrozap dew shield, and added that to the front of the scope. The sun was still setting, and I had a bit of a wait before two decent alignment stars appeared. I also found some small blinking red LEDs at Radio Shack that I used to mark the tripod legs and power supply. I found that these worked really well – people saw the lights and knew to walk carefully around them. They can be purchased in most stores, or online here.

I walked around to speak to some members, and had some great conversations about equipment, accessories, books, and the club. There were some new members, and we had a lot of fun looking at and discussing the new reflector mount.
As the night progressed, I had some great conversations with the guests, and really appreciated how friendly and interested the crowds of people were. We discussed equipment, various Messier objects and nebulae, and other fun geek stuff :)
I found that my scope performed better than ever, keeping objects centered in the eyepiece for as long as I wanted. I spent some time with Jupiter at over 350x, and even with the less-than-optimal seeing it was a fun view, allowing me to see more cloud bands than I’ve ever seen.

I observed a bunch of objects over the course of the night, including: the Ring Nebula, the Dumbbell Nebula, M13 (Hercules Cluster), the Wild Duck Cluster, the Swan Nebula, the Lagoon Nebula, the Trifid Nebula, the Eagle Nebula, and many others. I was impressed with the new nebula filter that I had just received that week. Based on several recommendations, I decided to buy the NPB filter from Omega Filters (available here). It really helped to make the various nebulae “pop” from the eyepiece. The Trifid was tough to spot, though I had heard from others that night that they had similar problems seeing it well. Not sure why.

I really enjoyed the southern views of Mingo, and spent most of my time observing that part of the sky. The Milky way did become visible as the night went on, but the overall brightness was not as high as other nights that I’ve spent on the hill. In fact, after midnight, the conditions began to get worse. Clouds began to form towards the horizon and haze ruined the south.

I spent the last part of the night with a few members and guests running the reflector. Having a true computer-controlled telescope is really a blast – just find an item on the screen (the computer uses The Sky software), click it, click “slew”, and sit back and watch the enormous 24” scope track in just seconds. It was fast, accurate, and whisper quiet. The mount makers should really be commended on their work, as well as the members that spent so much time and effort getting the new mount installed and configured.

Another great night out! Hope to see even more people for the next one!

Special Thanks to AAAP member and professional photographer Dave Smith for allowing me to repost a few of the images that he took at the party. For the entire set of images, please visit this site.

The NexStar Arrives - and I'm an idiot

I finally received the new Celstron NexStar 6SE telescope - it had been delayed for almost a week due to the floods out west. Thankfully, UPS was able to deliver it without incident, and even brought the 50lb box into the house (I wasn't home, and I'm fairly sure my wife didn't want to kill herself dragging a telescope into the house).

It looked PERFECT. I can't believe the deal I was able to get, considering the overall condition of the scope and accessories. They didn't appear to have been used at all! The seller delivered it in original boxes, and even the "warning" tags were still attached.

I was able to assemble the unit in about 5 minutes - it really is simple. I picked up a large plastic tub at K-Mart that fits the packing material for the main unit perfectly. The tripod and my accessories case fit inside as well, making this the perfect all-in-one travel case for trips to Mingo (and other dark sites). Unfortunately, in my haste to pack the unit back up, I never aligned the red dot finder. Mistake #1.

I wasn't anticipating using the scope immediately - it had been raining all day. To my surprise, the sky became clear at around 9PM, and I hurried outside to set everything up. I didn't realize until the next day that I had attached the finder incorrectly (hey, it was dark!). Mistake #2. I went about trying to do an auto align, but after 3 failed attempts I knew I was doing something wrong. Even when doing a single star alignment, it just was WAY off - 15 to 20 degrees off. I looked at the scope in daylight the next day, and realized the finder was mounted cockeyed. I'm fairly certain I had entered the time incorrectly as well. I'm an idiot. I'll try again tonight, with any luck.

Even so, I know a few things about the sky, so I checked out M13 manually (a very easy find). Larger and more detailed than my previous scope, for sure. I sensed something was up, though, when I had trouble getting tight focus. Sure enough, my corrector was covered in dew. Grrrrrr.

I'm leaving for vacation in two days, so there isn't time to order a dew shield and have it arrive in time. I may make one out of craft foam as a temporary fix - here's hoping there is less dew in Nags Head (not likely!)

Overall, a great scope. Really solid on the mount, excellent tripod, easy to use computer (when I know the time!). I also have my exact longitude/latitude (thank you Google Earth), so hopefully that will help as well.

Mars!

I was able to observe for about 25 minutes tonight. Problems with my finder scope and the odd patch of clouds hindered my session quite a bit, but I did get some time to view M42, the Pleiades, and Mars. At the clearest parts of the session, I had Mars near 200x, and was starting to detect some "seas" of darker color to the right of my view. Still, clouds came and ruined everything, and I packed it in after no further clearings looked likely.

New Year's Resolution: more aperture and GoTo. Passed on a few LX90s already this year, as I knew the weather wouldn't cooperate much in Dec/Jan, and I'd hate lugging an 8" SCT out for a 10 minute session.

I'm thinking of getting one of those inexpensive iOptron "Cube" alt/az mounts and a used 4" achromat just to have a grab-n-go scope for the winter. If it doesn't work well, I'm only out a few hundred :)

Clear (winter) skies,
Todd

More Orion

Took another early morning peak at M42, this time with the reflector. Hard to resist a calm, clear morning when it's so easily spotted in the sky. Since the moon was out and it was nearing dawn, there wasn't a lot of detail (oh, and my scope has a tiny mirror...lol...). I decided to spend a few minutes looking at the moon's terminator instead, since it was much more detailed. I'm dying for a larger scope!

Orion Surprise

I left for work early today, around 6:30AM. The sun hadn't come up yet, but most of the sky was covered in a thin layer of clouds. As I went to my car, I happened to glance up at the southern sky. There was Orion, perfectly placed in my view. Orion is my favorite constellation - easy to find, bright stars of various colors, and nebulas visible to the naked eye. I happened to have my 10x50s handy in the car, so I picked them up for a quick look at the sword and M42. Great stuff!

As I drove into Pittsburgh, the sun started to rise, and the colors of the sky were amazing. I love fall in PA.

Can't wait for winter, when the hunter is more visible and skies are more dry and calm (I hope!)

Clear skies,
Todd

Training at Mingo Creek Observatory

I was very excited and honored to be part of the first training class at the Mingo Creek Observatory over the weekend. Who knew the hobby would bite me so hard? :)

During the training, I learned the ins and outs of opening and using the observatory, and got some hands on training with the two massive scopes there (24" GoTo reflector, 10" refractor). The 24 has the new StellaCam3, a CCD camera which offers some pretty dang impressive views of DSOs through just the attached 5" refractor. I can only imagine what a larger scope can do. The 10" is a beauty - just a massive scope on an equally massive steel and aluminum EQ mount, all set on a pier. You have to really shove it to get it moving...it's fun :)

I stayed over the dinner break and watched part of the new Timothy Ferris PBS special "Seeing in the Dark". I will TiVo it later this month when it comes on. Great stuff for amateurs like myself. Who knew former Viking's running back Robert Smith was an avid skywatcher? Cool!

After dinner I did some more hands-on stuff and watched as the StellaCam3 was put into action. With a 30-second exposure we were able to see the central star in the Ring Nebula, and the nebula itself was bright and well formed.

I called it a night at 9PM so that I could spend some time with my wife - I'd been out for almost 6 hours at that point. The night was mostly cloudy, and the south was a complete washout with clouds and smoke from some concert's fireworks. I'll go back next week (now that I'm cleared to use the Observatory!) when my brother is in town.

Thanks to all of the AAAP members who helped with the training - it was a blast, and again, I am honored to be a part of the keyholder team. The picture below, from member Al Paslow's site, is the newly trained team. I'm the goof in the jeans, sunglasses and Firefly "Blue Sun" t-shirt.



Best,
Todd

Friday Night at Mingo Star Party

I journeyed out to Mingo park again on Friday, where the AAAP was holding another weekend of star parties. I meant to go Saturday, but Friday was looking good and my kids somehow got to bed early. Go figure!

I brought my usual gear, but this was the first time with the new eyepieces and case (pics coming soon). I setup my tripod, for the camera and binoculars, my scope (‘ol Blue), my beach chair and the small equipment table. The table is actually a kids folding table that I steal from my 6 year old. Remind me to get a real observing table.

Venus and Saturn were close together, but setting fast. I used the barlowed 9mm to view them both at 155x, which was a treat. It’s the largest I’ve seen either in this scope, and they both looked great. They moved fast, so I decided to try Jupiter for a while.

Jupiter stayed out all night, and Mingo has a GREAT view of the southern sky. I saw more in the south tonight than I ever have before. Jupiter and the 4 main moons barely fit into the eyepiece view at 155x, but I got them. Better detail than I expected, including 2 cloud bands and possibly the red spot (I may have seen it, or I may have wanted to see it so badly that I faked my own eyes out ;-)). At that magnification, it moved out of view FAST. Tracking would be a good thing to have on the next scope, so maybe the Dob is out after all.

By far, my favorites of the night came from Sagittarius, where I was able to see several Messier objects with just the binoculars. I spotted M8 (Lagoon Nebula), M20 (Trifid Nebula), and M21 in what has to be the prettiest binocular-ready section of the sky. The Milky Way was “flowing” right out of the teapot of Sagittarius, and made my night. I can only imagine what darker sites would do for this part of the sky.

I also spent some time on Antares in Scorpius, and again used binoculars to find M4. By this point, I was also viewing M4 and M25 through the 24” reflector Mingo’s observatory, so I was getting a little spoiled. This scope now features a rotating turret of eyepieces, so changing between the 5 or 6 magnifications was perfectly simple. A great star party addition, especially since those eyepieces were all Tele-Vue Naglers. What I’d give to have a set of those in my eyepiece arsenal! Someday!

I started packing up at about 12:45, just as a lovely reddish-brown moon rose behind me. I took several shots of the moon, none of which really worked. Ah well.

Overall, a great night! I met several new people, and I’m sure I’ll even remember their names someday (I’m terrible with names!).

Black Forest Star Party - Sounds good!

Just found the link to the Black Forest star party in PA. May have to grab some camping gear and check that out. My brother, a fellow star nut, said he may come as well.

Anyone have any thoughts on this one? Seems like a no-brainer!

First Observation with the new Binoculars

I finally had the time and the cooperating weather conditions to try out my new Nikon 10x50 binoculars last night. Overall, it was a decent night, slightly cool, and there didn’t appear to be any real cloud cover. Some definite haze as the evening wore on, but it was intermittent. Good or bad, I was anxious to see something, anything, in my new gear.

I knew I was going to have a hard time seeing much of anything – I’m in McMurray, just 20 miles south of Pittsburgh, and so the NNE part of the sky was visibly lighter due to light pollution. I also have a fairly bright gas-powered post light in my front yard (yes, they do still exist!) I decided to concentrate on the western part of the sky, as I could keep my back to the light. There were more stars visible to my eye than I expected, especially towards zenith. I got excited :)

I had already popped open Stellarium on my Mac to check the night sky. I’m still a complete rookie, so I need all the help I can get! I found a few landmarks, grabbed my planisphere and ran outside. I started with Venus, super-bright as expected. I star-hopped (still learning that, too!) to the twins of Gemini, also fairly bright and easy to find. I knew Saturn was “chasing Leo”, so I decided to hop over to the giant planet for a look. Along the way, I ran into a something I’d never seen before – I actually gasped as it came into view. I wasn’t expecting to see anything out there, and there it was, a lovely cluster spread out before me. Not visible naked-eye, which made it all the more breathtaking.

I had just seen M44 (the Beehive Cluster, or Praesepe)! Sure, that’s an easy one, I suppose. But I hadn’t found any catalog objects before this, so I was pretty excited. Now I was determined to see more.

Saturn was bright and pleasing to look at…even if I was shaking the binocular a bit by now. Once I dig out my tripod, I should get some more steady views. I honestly didn’t think the 10x50’s would get so heavy! Not sure, but I may have seen one of Saturn’s moons to the right side. Did I?

After a trip of a few well-known constellations, I tried to look for Hercules. I knew M13 was out there, hiding somewhere in the light pollution. Hercules proved hard to see in my location, the lights were washing out that part of the sky. Still, I waited, trying to let my eyes adjust. It took me a while to sort out which stars were which – the planisphere can be hard to get your bearings with. I finally was able to pick out a pair of stars on the left side (Rho Herc, Pi Herc), so I hopped up those stars, up again to Eta, and over to Zeta. I hope I’m getting these names right ;) Back and forth between Eta and Zeta…nothing. Using the averted vision method, which I had read about the night before, I spotted it! M13, a small grey puff just between the two stars of the keystone. Two Messier objects and two planets on my first night! Time for bed…I’m sure I’ll dream about huge SCT’s and apochromatic refracters (see, I am researching!)

First Star Party

I attended the April star party held by the AAAP in Pittsburgh. The party was held at the Mingo Creek observatory in Washington County, about 25-30 minutes from my house. Beautiful night, calm, clear, and cool.

It was my first party, so I brought my wife and 6 year old along for company :)

I got to see some great images of Saturn (with Cassini seps and moons! WOW!) and a few Messier objects (M3, M42), plus good 'ol Luna as it waned. Even saw Venus in one of its phases. Doesn't hurt that they have amazing scopes to take a few peeks through!

My 6yr old got tired early, but he was loving every minute. When I go to the next one in May, maybe he'll stay home. We'll see. I have decided to dive head-first into the hobby, and that means I do a ton of research. I bought a planisphere and a few books, my favorite of which is called "Astronomy Hacks". I must-read for the beginner, worth every penny.

The books and research led me to my first astro-purchase: a pair of Nikon 10x50 binoculars. I'll start with these (who knew you could see SO much with binocs?) and keep asking about scopes. For now, I'm looking at either an 8-10" Dobsonian or I'll wait and save the pennies for an 8" SCT (Schmidt-Cassegrain) with go-to computer control. I may eventually need a small grab-and-go refractor, but the binocs should do fine for now. Hooked, hooked, hooked.
