An Evening of Education

Tonight my friend Richard came over. It was his first light with his entire imaging setup. Celestron CG-5 AGT, Takahashi FS102 imaging scope, William Optics Zenithstar 66 guide scope, Canon 30D DSLR and Phillips SPC 900 NC as a guide cam.

A very good start for an astrophotography setup.

After a pretty rough polar alignment and a strange fiasco of getting alignment stars (neither of us really know that mount) at first, we tried some unguided shots and saw drift in an even 15 second shot. Got the auto guider dialed in and boom... 30 second shots with virtually no drift at all. Richard still needs a long exposure bulb cable and he'll be off taking 5 minute exposures in no time.

The Phillips cam was struggling finding a guide star. The DSI on my setup had 20 guide stars to choose from while the web cam was hard pressed to find even 1. I think I see an upgrade coming...

Whilst Richard was learning his gear, I was shooting away at M71 and the Deer Lick group.

Here is the info on my imaging session.

M71 Image
I shot 30 minutes of M71 not because it's such a spectacular object, but because I'd like to get the entire Messier catalog imaged. I figured that 30 minutes would be enough and I'm pleased enough with the shot.

Scope: Vixen R200SS 200mm @ f/4 w/Vixen R200SS Coma Corrector
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: 90 minutes - (18 x 300s)
Processing Software: Acquired in Nebulosity, Stacked in Deep Sky Stacker,
Levels, Curves and Noise Ninja in Photoshop
See Gallery below for image


NGC 7331 - Deer Lick Group and Stephan's Quintet Image
I thought I'd go for 2 hours of this, but ended up wih 90 minutes due to the sky getting a bit light after 3am. The framing may seem strange, but I was after not only NGC 7331 and Stephan's Quintet, but lso the many small faint galaxies in that region. I got them down past 17th mag in this shot from my front yard. There are dozens of galaxies in there. I'd really like to shoot this in a really dark sky. There is a star party coming up in a few weeks and I may put this group on my imaging list.

Of course you know I was only 'funnin' ya. It's a terrific picture. Faint fuzzies wherever you look.

LOLzerz. Yeah, it was framed to pick up all of those faint fuzzies. Pretty cool shot. I should have done it at OSP. Maybe it will be on the list for next year.

Yeh man, the framing on 7331 really sucks. What were you thinking? LOL You also need to clean the camera....to get rid of all those pesky fuzzy patches all over the picture. :)
