St. Patrick's Day with the Telescope

I decided to take advantage of the clear night to test out the new gear.  In addition to the new Antares finder scope (#1 in the picture) and 2" diagonal (#2), I had also picked up a slightly used Hyperion click-stop zoom eyepiece (8mm-24mm, #3) a JMI "wing thing" holder for my hand controller (#5) and some Earthshine port plugs to keep dust and grime out of my unused AUX ports (#4).

The hand controller holder worked perfectly - easy to install/remove and the height is adjustable.  It holds the controller exactly where you want it, freeing up your hands to focus, change a magnification, hold a flashlight, etc.  A very good investment!

The plugs are also perfect, and I've never seen them anywhere else.  They are just plastic covers for RJ11 phone jacks, but they are well made and easy to use.  Worth every cent :)

The new diagonal performed well, even if it was rotated slightly off center.  I'll see what I can do about that for the next session.  It is very well made, and the compression rings do a great job of holding eyepieces without marring them.

Once I got the Antares finder aligned, it too performed well.  Very nice optics - and at 50mm, it can almost be used as a wide-field scope.  Almost :)  The Pleiades fit nicely inside the field of view, as did the sword of Orion.  Made finding those objects (and others, like M44, the "Beehive") a cake walk.  SO much better than a red dot finder.

The only issue that I had that night was with the new Hyperion eyepiece.  It just didn't provide pin-point stars, regardless of the magnification.  Sure, the conditions weren't perfect, so I'll blame that for part of it.  And I guarantee that my scope is not perfectly collimated (but it's close - I tested it on Sirius and got a pretty good set of concentric circles when defocused).  I compared the views in the Hyperion to my 25mm plossl, and the plossl was better.  I need to have a better look at the EP in the light - maybe it's dirty...

I decided to take a few quick views of Orion, looking at Rigel and M42.  The Hyperion could not split the stars of the Trapezium at all, while I know that I've done it with my plossls.  Hmmm.

I hovered around Canis Major, Gemini and Monoceros as well, finding some nice Messier objects in their midst.  I love me some star clusters :)

I called it a night when the combination of cold air and the neighbor's driveway lights (never usually a problem) made observing too difficult.  I hope to get another shot when I get back from my business trip to Tennessee and Georgia next week.

Clear Skies,

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.

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!).

Building a new Eyepiece Case

With my recent purchase of another eyepiece (a 9mm Super Plossl), I am slowly building up a collection of gear that is no longer fit for a shoebox ;) I decided to look at eyepiece cases, and found quite a few. Most are expensive, and I'm a cheapskate. I decided to take the advice of several online write-ups and bought a case at Lowes that should do the trick.

It's a tool case, but comes with an insert made of the "diced" foam - this allows for easy customization. I should be able to get all of my eyepieces (32mm, 25mm, 9mm, 2x barlow) into the case, with plenty of room left over for my LED flashlight.

I'll take pictures of the final case, but here's a picture of the Lowes case from their website. Should be around $25 in the stores (maybe less, maybe more, depending on sales).

A beautiful night for Luna

Last night was clear and cool here in Western PA, so I took all of the gear outside for an hour or so. I finally got to use the new barlow to view Saturn and Jupiter at higher magnifications - what a difference! Saturn is lower in the sky now, and is blocked by trees from my driveway almost as soon as it is visible. I ended up wandering down the street to my neighbors driveway to get a better view - I'm sure they all think I'm nuts.

Saturn through the barlowed 25mm eyepiece was about 56X magnification, and showed two moons and defined rings. I need to get a 8mm or so to really max out the magnification of the scope - it was a great view.

Jupiter was high in the darker eastern part of the sky, and the larger magnification helped me see 2 or 3 bands of color across the surface of the planet. The 4 large moons showed up 2 per side, making a nice view in the eyepiece. I'm sure the 8mm would be worth every penny on this planet as well.

I got distracted by the moon midway through the viewing session - it was a bright crescent in the South West, and I spent a while looking at the surface at 56x in the 25mm and 22x in the 32mm. It was such a nice view that I took the picture you see at the right. I think this was taken at f3.2 and ISO100. I'd have to check. I used my Canon S2IS digital on a tripod, and used the 10 second timer. Not bad! Took about 15 shots, and this was the best.

What I didn't remember, however, was that the ISS (International Space Station) was due to pass by the moon just before 11PM. Not only that, but the recently undocked shuttle would be following it, only 10 degrees or so behind. Only after I came in did I read how great a sight it was. RATS. Hopefully my brother in VA got to see it (he's been waiting all week).

As usual, I picked out M13 to close out the night. One of these days I'll get out my charts and plan an actual session. Likely I'll save that for a star party with darker skies and more time.

Bought some new eyepieces

I found some inexpensive eyepieces on Ebay (SmartAstronomy's store, ebay id Ruby123) and decided to give them a try on 'ol Blue (the Bushnell 3" reflector). These are Guan Sheng eyepieces, rebranded for SmartAstronomy. As far as I can tell, there are others (including Celestron) that offer the same ones with different branding.

I bought a 32mm Super Plossl and a 2x Barlow (both 1 1/4" and fully multicoated). They arrived in only 2 days, were packed very well, and came with dust caps. They were further wrapped in small baggies and placed inside nice little boxes. The 32mm also has fold-down rubber eye guard. Nice touch.

The 32mm preformed well - nice eye relief, wide view (52 degrees, according to the specs), and good overall contrast and darkness of the sky. Stars appeared sharp to the edges of the field as well.

The barlow also worked well, but the focuser in 'ol Blue has a rivet inside that doesn't allow easy insert of longer eyepieces. Thank you Bushnell. I did get it in, but it isn't easy. Not the way to go when you're trying to do a simple swap to get a little closer to a DSO.

I did manage to get a nice view of M13, easy to pick out now that I'm learning my way around the sky. It was late when I tested, so the planets were out of view (behind trees or already set). I'll try the planets again soon.

Overall, a great deal at under $50 for both. I'll likely pick up a 9mm to go with the set, since the price is right and the company is SUPER easy to deal with.
