Based on the size of your Jupiter image (and your aperture and camera), I estimate you are imaging at about f/11.1 (or 3.8x the pixel size of your camera) which is pretty close to optimal.

The sharpening tool in AS!3 is only really meant to be an indicator, there are better programs out there for sharpening (Registax is the default standard, but Astra Image and a newish program called AstroSurface are also used).

Can you give more details of your capture process? Capture time, frame rates, that sort of thing? FireCapture records a logfile for every session, if you want post one of them, that would be helpful too.

Hey Andrew,

Yeah, you are probably spot on. F5 x2 barlow so F10 or there abouts. I have a 3x ED barlow to get me to around f15 which is about optimal but haven''t used it yet.

Unfortunately i've already deleted the .ser and log files as my laptop hit capacity and needed space for next session just got the un edited stacks.


I captured in 600x600 around around 3 minutes for both Jupiter and Saturn. Couldn't go longer for Saturrn due to drift and only just learnt about the Autoaline feature which is plan on using next time out. Frame rates were between 90-120 for Jupiter and i cant remember for saturn but was quite a bit lower from memory.

autostakkert - 75% stacks seemed best quality anything lower than 35% had a square artifacts.

Registax wavelets (no idea what i''m doing just guessing) and RGB balance.

final sharpen and curves in Photoshop.


Oh and the Jupiter edit without the BRS was a winjupos image denotation of 3 of the images. Tried with Saturn but couldn't get it working properly.

cheers Greg
