M13 with a modified Samsung SDC-435 camera and an f/5 150mm Newtonian, Jupiter, the Moon and the Sun

The SDC-453 camera was fitted with a light pollution filter and the AGC was set to LOW.

15min of DVD were captured. The BMPs were extracted from the DVD VOB files, and stacked in Registax. The dark-frame used was corrected by Andrew Sprott's Dark Frame Scaler:

M13

I used a DMK21AS camera at the Prime focus of the 150mm Newtonian and imaged the terminator and most of the Moon. This is a mosaic of 5 images. With a little more care, I could have imaged the whole thing. Remember to click on the image to obtain a larger view:

Jupiter was imaged with the monochrome DMK21AS camera through a 3x Barlow with RGB colour filters and a colour image rendered in Andrew Sprott's CAP software:

The Sun was imaged in H-alpha light and Ca K-line light with the DMK and PST scopes. AR1101 and 1102 can be seen in the images:
