The Propeller Galaxy (NGC 7479) is located in Pegasus around 105Mly distant. A relatively recent minor merger has caused the Propeller to rotate anti-clockwise & starbursts are being observed in the outer arms & nucleus. It has an
apparent magnitude of 11.6 and measures only 4.1 X 3.1 arc min. I processed about 8 hours of LRGB data to create this image.

Here lies my attempt to image a challenging distant galaxy group. Stephan's Quintet is a
visual grouping of 5 galaxies located in Pegasus. The galaxies are interacting with the
exception of the largest galaxy (NGC 7320) in the forground about 40mly distant. A sixth
galaxy (NGC7320C) is beleived to be invoved with NGC7319 & its tidal tail. The rest of the
group is located about 290mly away. The image was taken through LRGB filters with 10 minute
sub exposures. The best of about 13 hours of exposures were combined to make this image. A
long exposure time was necessary due to the apparent magnitude of theses objects (14-16.7) &
the local seeing conditions. Processed in CCDStack & Photoshop.

Here is a quick mono image of supernova PTF11kly in Galaxy M101. It was discovered on August 24th and has increased in brightness. Due to its low altitude in the NW, I was only able to capture 60 minutes of luminance data (6X10 min subs). The supernova is located on the Southern side of the galaxy as marked. Processed in CCDStack & Photoshop.

M27 again..this time with guiding. Following instructions found on CN, I converted my 8x50mm finder to a guider with a pvc plumbing reducer and velcro for shimming. A bit McGuyver-ish, but it fits the tube snugly, and my DSI II quite well also. And it works well with PHD.
This image was taken with my LX200 10" Classic f6.3 on a Meade SuperWedge, Canon 1000D, and an IR cut filter. 20-4 min lights and darks, stacked in DSS, and tweaked in PS CS5. I Used BackyardEOS to manage the camera (fantastic piece of software), which works flawlessly.
Taken from my driveway 7/29/11 at midnight. Thanks for looking!

M16...again. Actually imaged this at full focal length of the Meade 10" LX200 (2500mm) under a 80% moon (7/19/11 11:30 PM). Used the Meade 10" and Hap Griffin Modified Canon XSi for image aquisition. Guided by the Explore Scientific 80mm APO and Lodestar. 28 - 5 Minute Subs, 5 Darks, 40 flats and bias. Image aligned and stacked in Images Plus 3.82 and processed in Photoshop CS3. Please bear in mind that the moon was out and no blocking filter was used. I just wanted to try long focal length imaging as I plan to do a lot of this in the future.

Here is my latest subject, M27, the Dumbbell (my wife says it's appropriate....lol). Captured on 7/8/11 with My LX200 10" f6.3, focal reducer, and DSI II. The night was what I would call good seeing, light breeze, good tranparency.
50 exposures, 45 seconds each, I used Meades' Envisage SW, and processed in PS for levels and saturation (not much).
Let me know what you think!

A Study in Globulars - M4
Magnitude 7.1
Distance from earth: 7,200 ly
Distance from galactic center: 19,200 ly
Constellation: Scorpius
Dimensions: 26' imaged
Diameter: 75 ly
Distinctives: This is one of the two closest globulars to us. It has a distinctive central vertical bar.
Meade LX200GPS at f/10 guided; Canon 30D modified; ASA1600; 10 sec subs X 60; Deep Sky Stacker and Photoshop post-processing.
I enjoyed placing these three globulars (M4, 13, and 19) right next to each other and directly compared them. This teaches closer and more detailed observation skills.

A Study in Globulars - M19
Magnitude 6.8
Distance from earth: 28,000 ly
Distance from galactic center: 5,200 ly
Constellation: Ophiuchus
Dimensions: 5' visually; 13.5' imaged
Diameter: 140 ly
Distinctives: Most oblate of the globulars; I tried to do a rough measurement and found the long axis about 15% longer than the short axis.
Meade LX200GPS at f/10 guided; Canon 30D modified; ASA1600; 10 sec subs; Deep Sky Stacker and Photoshop post-processing. I took 75 subs, the first three of which were 30s, 20s, 15s, and the rest were 10 seconds to see if I could bring in more detail w/o washing out the core. I am not sure I succeeded.

Here is my first contribution to the group! This is M57, taken 7/1/11 in good seeing. LX200 10" f.3, focal reducer and Meade DSI II, 50 frames, dark subtracted.
Processed with FITS Liberator and Photoshop. You can just see the central star in the ring.
I have been using my LX Classic Alt/Az, but just put it up on a SuperWedge on July 1, 2011.
I have a LONG way to go!
