Wedge CCD Align
Hi guys,
I was given a article on ccd drift method by Robert Vice for fork mounted sct by Bintel. The instructions seem simple enough but I was thinking about this method. Have attached article.
The instructions do not state if using no wedge or wedge mounted. I assume no wedge or ALT/AZ as you slew east and west to take a exposure. If you have a wedge then the star image photo will not be horizontal due to you setting the altitude to your latitude.
When you do the initial setup of scope being in Sydney, fork is pointing scp and telescope tube is approx pointing to northern meridian. For first step, can you use a star in north or do I need to rotate ota towards south meridian, follow process and also rotate dslr to be right way up.
Has anyone tried this method.
Regards
Kon
