The numerous replies received to my submission, Colour compared to Mono

DMK CCD imager has shown me that I’m not alone requiring similar information and. with this in mind I’d like to lean on you Iceman Mike with your expertise and ability to explain in detail how you set up the telescope, recorded the crater Clavius and processed it, and in doing so cover the questions below. Something along the lines of your planetary article, keeping in mind the elderly slow learners.

Replying to one of my questions you wrote, a Astronomik (?) red filter was used to capture this magnificent picture. Why a red filter and details of the filter, such as name and where it can be purchased. For those who cannot afford a full set of filters and adapter, can the red filter screw to the 1.25 inch adaptor that comes with the DMK mono imager and be used as a single filter and recorded as AVI file.

For those who gave their time to reply to my questions, I finally decided on mono and as I’ve never recorded in B&W, I tried it with the Toucam. In my opinion Greyscale looks too deadpan blue and I gave the attachment a slight colouring in Photoshop. If the DMK mono is better than this first attempt, I’ll be happy with B&W. Thanks all
