Hi All,

I didn't want to pollute the any infor on the 10" RC thread any further, so I started one here to discuss the merits of each type of scope.

One rule, keep the comments civil and nothing personal. No sniping (OK that's two rules, I'd better come in again...).

Anyway, Bratislav and I imaged the same target within days of each other, me with my 8" RC as it came from Peter (it needed a tweak of the collimation and got a new focuser), so I'd say my pictures would be ever so slightly better now. Bratislav used his 10" newt, I don't know the focal length, but it seems to be a little less than the RC judging from the picture's FOV.

I have not done much to these pictures, and they are single subs, Bratislavs came up as a 60 second sub, mine is twice that. I calibrated mine, I think Bratislav's came to me calibrated, I used a touch of sharpening on mine as it showed some seeing induced errors (the base of the stars' peak has been spread, so Bratislav got the better seeing). I tried to do the same to Bratislav's picture, but it looked bad.

I have cropped the field showing part of the core and the best focussed bit of mine (I have since learned how to get most of the frame in focus). I think that the two images are virtually identical.

Let the discussion begin, remember that the Spanish Inquisition are watching and will lock the thread if you start to get nasty!

Cheers
Stuart
