B33 by bruessow (January 2007)

AstroTech 66 with WO 0.8x Reducer/ Flattener to take this image.

SBIG ST2000xm, unbinned H-alpha 16x5 min, G and B were 7x5 min.

I am having fun with this little scope...

M63 by Chuck Anstey (Mar 2007)

M63 shot over two nights March 11th and March 12th, 2007. Skies were below average transparency and straight at Atlanta, GA light dome so LP was high. The noise per sub-frame exposure was 45-50 ADU RMS so I figured I needed between 50 and 60 frames to drive the noise down to the correct level. I was able to simply let the AP1200 image unattended all night long so I got 68 frames.

Equipment:
Telescope: Celestron C11 + Focal Reducer
Mount : AP1200
Camera: SBIG ST-10XE + CFW8a + Astrodon Tru-Balance LRGB filters.

Conditions:
Transparency : Below average
Seeing : Between 2.6 and 2.1 FWHM (4.0 to 3.1 HFD) over the course of the night.

Exposures:
L: 6 minutes x 66 frames (rejected two)
R: 6 minutes (2x2) x 9 frames
G: 6 minutes (2x2) x 9 frames
B: 6 mintues (2x2) x 8 frames (rejected one)

I had an additional 6 RGB frames each but they did not improve the color image when I added them.

Processing:
CCDSoft: Dark, Flat, Align
CCDStack: Stack and create color frame
CCDSharp: Lucy-Richardson deconvolution on Luminance
Photoshop CS2 : Image processing and LRGB combine

Meade 16 LX200 at f3.45
78 total minutes in 60 and 90sec subs.
Orion Starshoot (original model)
Imaged 7-8-10 Sept 2007

"Added 20/90sec more exposure and this time at f4.3. Total time something like 110 minutes made up of 60 and 90sec subs exposed on 7,8,10,11 Sep 2007. Orion Starshoot (original),no darks, flats, guiding or other distractions. As before, Meade 16 at f3.45 and f4.31 composited with Picture Window, cleaned up in Photoshop with the help of Neal Carboni tools."

Jan 2008 (IC2118)

This was taken on the night of January 7th from Chiefland Astronomy Village in Chiefland, Florida. Imaging at 29 degrees of latitude N was a real help on this image.

RGB 70-70-120m using 10m subs. TV-76 with 0.8x reducer, SBIG ST-2000 with CFW-8 and Astrodon filters, EM-200 mount. 5 sec guide exposures using the ST-2000 guide chip. Calibrated, aligned and sigma reject combined in Maxim. RGB channels merged and processed in PSCS.

Feb 2008 (NGC 2841)

Taken 02.February 2008 from my "Garden-Observatory" in Germany.
Optics have been a Intes Maksutov MK-67 150/1800mm @ f/12
Camera was my SBIG ST-2000XM and CFW-9 with Astronomik-Filters.
The diffraction spikes are caused by my focusing aid, which
i glued in front of my telescope...

L:R:G:B with 255:40:40:40min
15 minute Subframes for Luminance bin 1x1
5 minute Subframes for RGB bin 2x2 (a little to short exposures to get real good colours....)
All frames selfguiding with cameras built in chip.

Image reduction in CCDSoft
Subframe combining in CCDStack
RGB combining in CCDStack
LRGB combining and final adjustments in Photoshop CS2
