Here is a third image I have taken with the Artemis285. This is M13. I have attached a mid size thumbnail but a full size image and exposure and processing details can be seen at:

Scope was my C8 at f/7.2 (with a Celestron f/6.3 reducer / corrector). Total exposure time was 34 minutes.

It seems to be in colour. Is that the colur version of the Artemis? Or did you use filters?

Thank you all for the comments.

Denise, the reference given is indeed the website of the designers / suppliers (kit form).

Stuart, the camera I was using is the monochrome version. So I do 4 exposures a luminance and R,G,B each with R,G,B dichroic filters). I combine them in postprocessing to form a color image.

Jim, you've put together a world class image of M13. The detail is great and the color is perfect. The camera is a winner and your excellent processing shows that well.
