Thursday, May 21st, 2009
So tonight I went out before the star party to try and see if changing the distance between the sensor chip and the corrector would make a difference in the star shapes. It didn't appear to.

And on top of that, I was having strange drift issues even though my guide graph looked pretty good. All the stars are oblong. Waaaaa... I hope I can get things dialed in quickly on the first night of the star party tomorrow otherwise all of my images will have sloppy stars. I guess even if they do I'll still get better images then I would here at my house.
 
Here is the image I took after dinking around. 45 minutes of M27.

Dumbbell Nebula (M27) Image
I've shot the Dumbbell several times in the past, but the last time was 2 years ago. My equipment and experience have both improved since then and this shot is pretty decent.

Mount: Orion Sirius EQ-G with GoTo
Guiding:  Meade DSI Pro and PHD Guiding
Guide Scope: William Optics ZenithStar 66 SD
Camera: Canon EOS 20D (unmodified)
Special Settings: None
ISO: 800
Exposure: 45 minutes - (9 x 300s)
Processing Software: Acquired in Nebulosity, Stacked in Deep Sky Stacker, Levels and Curves in Photoshop

that's a really cool picture of m27 (i like to call it m27 because it doesn't look like a dumbell whatsoever).

Of course.....2am....5/21. You will have to excuse me, I'm a little slow.

Thank ye kindy Barr.

And yeah... I took it last night though it was 2 am so technically it was 5/21. 8^)

However, there is a kind of a bug in this site where you can only have one entry per date. Two entries with the same date make it glitch. I guess I could have made an addendum to yesterday's entry.

LOL....

Nice image....lots of dim stars...minimal bloating. The definition in the nebula is outstanding. Nice job of processing.....you are getting to be a pro!

You must have captured this last night, 5/20/09.....since it's not dark yet tonight.
