All posts for the month February, 2008

Orion Nebula - M42I almost decided to hit the Mellow Mushroom for a beer but instead just went on home and got ready to set up the Scope and take some pictures.

I messed around with some computer stuff first, then watched a little TV. Around 6:30 I started to setup the scope and stuff outside, it was already around 36 degrees (F) and dropping fast. First I pulled out an extension cord, plugged in the camera and mount AC adapters, brought out the metal table, and then setup and leveled the telescope mount. I then mounted the OTA (optical tube assembly or telescope), and added the T-adapter and camera T-ring to the focuser on the scope. My brother then helped me collimate the finder scope using one of his eyepieces and a flip mirror (later in the evening he gave me an extra (3rd) one he had, he’s really nice that way!). I’m going to have to do it again later since we only did it with an object less than 100 yards away (it should be more like a mile or so). By this time it was dark enough to see the north star (Polaris) so I polar aligned the CG-5 mount. Had a little trouble with this since there were a few clouds moving to the east right over the top of the celestial north.

I then began to align and calibrate the GoTo on the mount. Most of the stars I’m familiar with are in the Southern sky, Betelgeuse, Rigel, Sirius so I was just using them and Brian started his sarcastic way of saying I was doing it wrong, I knew that I wouldn’t get a really good calibration but exact GoTo was not something I was really worried about. I told him I knew that it wasn’t as good but I wasn’t worried about that and he took it as if I was telling him he didn’t know anything. Funny thing is I know and do ask him about almost everything I do for the first time or at least get his opinion, I may not use it but I think that is my choice.

Finally, with my hands nearly frozen I had the scope basically aligned and began to set up a picture taking sequence. I did a 6 photo run for 10 minute exposures with 5 minutes between them in order for the camera to do it’s noise reduction. It was too much and there was a lot of wiggle, and some drift. I hadn’t done any drift alignment so I expected this. I then did a six shot run with 60 second shots and only got two that were not streaked at least a tiny bit. This may be from the mount movement, improper alignment (drift) or maybe the mirror since I did do the exposure delay but not mirror lockup.

NEXT: Use the 2X converter with the camera to get a bit closer to the nebula, and then possibly try another nebula or star cluster. M17: the Omega Nebula, M31: Spiral Galaxy, M20: Trifid Nebula

Lunar Eclipse with SaturnI stopped in at the Mellow Mushroom for dinner and a few beers before heading home to view/photograph the lunar eclipse. Amanda was there along with Kat (Katheryn?). A fellow server (the dude) had called in and wasn’t going to make it, he had called earlier and another server told him he wasn’t on the schedule. Nicki called while I was finishing my beer and was at the house hoping to get her tax forms printed so she could get them sent out tomorrow. I finished my beer and becoming a little pissed off at the news about Obama. Seems his wife has NEVER been proud of America/Americans or politics except for the people wanting her husband to be president. Personally, I feel he may be the anti-Christ.

I got home and started Nicki finishing her tax stuff, and printing it out. Then I started setting up the camera for the lunar eclipse. It was somewhat cloudy, only wisps but right in line with the moon. It was still behind the trees to the east but was coming up fast. By 8:30 I was getting the mount aligned and trying to get the focus right. Something went haywire with the mount and it got off alignment somehow, right after I tried to have it seek to Saturn (it was just below the moon). Re-aligned and then started shooting the moon so to speak. 🙂

Lunar Eclipse coming out of TotalityBy the time totality occurred the clouds had came in quite heavily, and stayed that way for some time. Around 10:45 it started to clear up a bit and I got some more shots like the one above with Saturn in the lower left-hand part of the frame. The shot to the left is one just as totality was complete and the lower right edge is beginning to emerge from the Earth’s shadow. It was after 11pm by then so I started packing up and getting the stuff inside. I was tired and sore (all the bending and standing on my feet for the last 2-3 hours, I’m not as young as I used to be.

The moon will be totally eclipsed from 10:00 to 10:52 p.m. Eastern Standard Time.

Start will be around an hour and a quarter before (and after) so the start will be around 8:43pm and should end around 12:09am, these times are from the article here from Sky & Telescope Magazine.

This will be the last total lunar eclipse for the Americas until Dec 2010.

Just as a note to myself, looking at other photos of a total lunar eclipse, try ISO 200 f/6 at 8 sec. and vary from there.

Moon rise is at 6:10pm EST. Sunset at 6:25pm EST. These times are from the USNO website.

So far the weather looks like it may be OK for the eclipse. So far.

Decided not to get the OTA that I was looking at, the focuser is a rack and pinion, so I’d have to buy another better focuser for about $200 for a total of $700+ and I can get a brand new OTA for around $900 with better glass and the better focuser. I need to just think about this for awhile.

I did get my Federal Tax Refund today as well as my “bonus” at work. Just a bit over 2% I think, it will allow me to catch up and order some cool photography stuff and pay off my brother for the CG-5 mount. Earlier this morning I had more money than I’ve had in my account since just before I bought my house.

Ordered a multifunction remote and a right angle viewfinder for my D200. The viewfinder description is for a screw-in type and the one compatible with the D200 is a slip-on but the part # is for the newer slip-on. I wonder if they got it wrong or if I’ll be getting the correct one. Should arrive around Wednesday for the lunar eclipse.
