Thank you everybody for replying to my questions:
Paul, I'll check out that link, the collimator I used was a laser one....that went back today and I'm waiting for a Cheshire to turn up tomorrow. I do tend to jump in at the deep ends, but I tend to enjoy the task. Thanks.
Carbon Brush, Yes it was new, but the problem is they are about 200 miles away from me, we seem to be starved of Telescope dealers these days where I am (Essex), But....If push comes to shove! Thanks.
Bosun21, I may ask him the question after I get a result tomorrow, thank you for that, I'm assuming I just leave @Chris a 'Public message'? (not sure how it works) Thanks
Anne S, Thats interesting stuff, I worked my way up to using all the extensions and found I still needed another 10mm; I achieved that by pulling the camera out by 10mm at which time I managed to take a few images of the moon. Although they were 'ok' I had to stack a lot of them to get it anywhere near reasonable. I was at that stage I contacted RVO, and I was less than impressed with their answers. Then Moon was almost in focus but then its a lot closer and bigger than the stars. I'm beginning to get concerns about the mirror distances now but I don't know enough about that aspect yet, (it may explain why I needed to use all the extensions) after I collimate it again tomorrow I'll do some research on that. Thank you
