Hi Malcom,
Thanks for your detailed reply, and beautiful Jupiter images in your gallery with great colour. I use the crop video mode of the 550D which uses the central 640x480 pixels of the sensor and records at 50 frames/sec. The maximum I record for is 2 minutes (6000 frames) although 30sec-1 minute is more normal. I don't have the computer connected to the camera at all, I just download the video to disk after.
I would like to work on my optical setup, which would hopefully give a greater image size. I'll look at getting a Barlow which will let me make comparisons with the teleconverters - hopefully I'll be able to stack them all too! There is still much to learn, and the great images posted here are an inspiration.
I'll go looking at colour alignment techniques to improve what I already have.
Cheers,
Tom
