Focusing

I have an 8 inch reflector with a 2 inch revelation focuser and a canon 1100d mounted and whilst it was clear i tried to get a picture of the moon to test it out. I didnt have time to get it all aligned for anything more spectacular but could not get it focused. I had the focuser all the way in but it just needed a little more. There were no other adapters i could take out so it was as close as i could get it. I dont have a 2 inch barlow as im sure that would have sorted it as had the same problem with my webcam but as i understand you dont want to be using barlow lenses for imaging? Can anyone help?

Thanks

Phil.

I've seen two solutions to lack of "in-focus". One is to obtain a low profile focuser, the other is longer collimation bolts to move the primary higher up the tube (requires longer springs too). Big difference in cost obviously.


 


Just thinking out loud - I wonder if a reducer would do it? Not tried it myself but maybe someone will comment. :)
