Atik CCD question

[Kai]

Is there any advantage using a 2 inch nosepiece over the 1.25 supplied ?

Thats all

Not really, vignetting shouldn't be a problem with such a small chip, it's kind of noticeable with a DSLR at f/5 (steeper light cone) but not massive.

I couldnt really think of a reason but i had to ask

Depends what scope you are using , i had terrible troubles with my gps 8 and also the ed80 , so i now use the celestron 6,3 reducer, which is brill no vignetting or coma , the inch and a quarter and 5 x reducer just did not produce good images.

Hi Rog

I planning on the C8 and a celestron focal reducer.
