NGC5792, a spiral galaxy in Libra, magnitude 12.1, dimensions 6'.8 x 1'.7. This is a composite image created from 33 exposures totaling 33 minutes, all taken between 3:45 a.m. and 4:47 a.m. the morning of the 7th. Images were taken using the f/6.3 focal reducer, for an effective f/ratio of f/4. Images were processed with dark frame removal, flat frame, then compositing, and finally a contrast stretch. This image needs another 30 to 45 minutes of integration time to reveal more details.

NGC4565, an edge-on spiral galaxy in Coma Berenices, also know as the "Needle Galaxy," magnitude 9.6, dimensions 16' x 3', distance about 31,000 light years. This is a composite image created from 30 exposures totaling 30 minutes, all taken between 1:41 a.m. and 2:43 a.m. the morning of the 7th. Images were taken using the f/6.3 focal reducer, for an effective f/ratio of f/4. Images were processed with dark frame removal, flat frame, then compositing, Digital Development (FFT low-pass, hard), Unsharp Mask (FFT hard), Kernel Filter (low-pass) and finally a contrast stretch.
