Dear padbravo, Thank you for comments. Writing this instructable and discussing the comments was a real pleasure for me also, it helped me clarify a lot of things. Now to answer your question: I would first try the method explained here http://www.wikihow.com/Collimate-a-Newtonian-Telescope-Spending-Zero-Money This requires a) to make a small centered hole on an eyepiece cap, place it on the eyepiece holder and adjust the secondary mirror and b) to locate the exact center of the primary mirror , mark it with tape and align. Wish you luck1
Dear padbravo, Thank you for comments. Writing this instructable and discussing issues in the comment section was a real pleasure for me also, it helped me clarify a lot of things. Now to answer your question: I would first try the method explained here http://www.wikihow.com/Collimate-a-Newtonian-Teles... I would go for this method, it seems clear and straightforward. You need to a) make a small centered hole on an eyepiece cap, place it on the eyepiece holder and adjust the secondary mirror and b) locate the exact center of the primary mirror , mark it with tape and align by eye . Fine tuning requires the observation of a star , better Polaris. Wish you luck!
I am glad that this instructable was helpful.
Thanks JRvZ,Indeed the carrier could be constructed in a better way e.g. by making a simple grove-slide mechanism. However I focused on the lighting and exposure issues as well as how to keep the film flat.
