The image above was created by aligning, stacking and processing the best 50 images in the "minute" window of LCROSS impact at 4:31 AM PDT on October 9, 2009 at the Palomar Observatory grounds.

The image stream was captured via a 12-inch Meade LX200 ACF at prime focus with a Point Grey Scorpion Firewire Camera.  I used a MacBook Pro with Asto IIDC to capture, align, stack, and perform the initial processing.  Final processing was completed in Adobe Photoshop.

The Sagittarius mosaic was shot with a QHY8, a 6 megapixel cooled CCD.  I calibrated, debayered and stacked the individual channels in CCDStack.  Also did the color balance in CCDStack with a bit of pixel maths.  I then use Register program to register the mosaix then finished off inPhotoshop CS5 to do the blend, saturation, etc.
This was 7.5h total integration times in 5 min. subs for 5 panels.  Guided on a Losmandy G11 Gemini with a QHY5 and PHD guiding software.  I used nebulosity v2 for image capture.

Photo taken by Dennis di Cicco and image processed by Sean Walker of the 2009 Easter Island eclipse.
The exposures were made with a Nikon D700 camera at ISO 200, using a 600-mm f/7 "home-made" refractor (the objective is from a Tele Vue 85, with a "low-profile" focuser and a HoTech field flattener). The telescope was fixed (non-tracking) -- the objective end was resting on a rock wall, while the camera end sat on a low tripod.
 This image is assembled from a series of exposures ranging from 1/500 to 1/2 second, made using the D700's 9-frame auto-bracketing feature (a total of 36 frames were used -- four groups of nine exposures). The processing was done with the software and method described in the June 2009 issue of S&T, page 64.
