Crescent Nebula C27 with a 10" f/4.8 Newtonian and a 0.5 focal reducer

On September 16 I used the modified SDC-435 fitted with a light pollution filter and a 0.5 focal reducer with an f/4.8 10" Newtonian. The AGC was set to HIGH

M57 with a modified SDC-435 and a 6" Newtonian

On August 30 I used the modified SDC-435 fitted with a light pollution filter at the prime focus of an f/5, 150mm Newtonian. The AGC was set this time to LOW:

M13 with a modified SDC-435 and a 6" Newtonian

On August 30 I used the modified SDC-435 fitted with a light pollution filter at the prime focus of an f/5 150mm Newtonian. The AGC was set this time to LOW which produced less saturation and lower chrominance noise in particular:

There was a bright Moon in the sky but a pleasing result was obtained

M82 with the modified Samsung SDC-435 and an 11" SCT

The camera was fitted with a light pollution filter and the scope with a 6.3 focal reducer. DVD was captured in high quality and 244 useful frames were extracted with VOB Frame Extractor. The frames were stacked in Registax using a dark-frame scaled correctly using Dark Frame Scaler:

Under a full Moon imaging M57 with the modified Samsung SDC-435 and an 11" SCT

M57 the Ring Nebula

The sky was quite blue but the ring nebula still made a nice real-time observational object and a reasonable image.

Exploring Sagittarius with the modified Samsung SDC-435 and a 130mm AZ GOTO f/5 Newtonian.

The camera was fitted with a light=pollution filter and 15 minutes of DVD were recorded at high quality for the images and dark-frames. The BMPs were extracted from the DVD VOB files using VOB Extractor. The dark frame was scaled with Dark-frame scaler and the BMPs were dark-frame corrected, de-rotated and stacked in Deep Sky Stacker.
