Turns out there was only 3 discs worth doing


first success this time around getting Firecapture to control the filterwheel.


next job to control approx focus on the diferent filters


 


8" SCT on NJP mount with x2.5 powermate DMK21


30 fps on R & B


60fps on L & G


 


3000 frames L


1000 each rgb


 


stacked 50%


 


run through pipp the auto stakkert 2 and then into PS (no wavelets this time)caf471fcc15d3b4378dde075a34d5669.1824x0_

I think you are capturing too much and therefore it takes longer and you are getting rotation blur which is more evident at the edges.


You need to get your capture down to about 3 minutes total for all the filters.

thanks


 


thats the thing Andy they are taking less than 3 mins to do now


 


3000 takes 50 secs


1000 at 60 = 16


2 x 1000 at 30 =60


 


and 10 secs between each all auto


 


 


I will try reducing the L to 2000 and 1000 next time out


 


thanks for the suggestion all help welcome


 


 


its the onion ringing effect thats really annoying me


 


 


 


 


 


which takes  just over 2 1/2 mins

The onion ring effect is usually because of too much gain and pushing the wavelets too much.


 


What model DMK21 is it old or new?


 


I know they don't recomend going over 30fps on the old model.

the old one


 


another thing to try to limit it to 30fps


 


I'm sure it was not this complicated 2 years ago when I last did planetary imaging :D


 


I only used to do rgb


 


only tried the L the last session


 


also going to check the corrector plate is afternoon as the scope has been sat in the conservatory for the past year


 


 


have you tried that win jup that de rotates it? out of interest

Here is a quote from a very knowledgeable planetary imager and camera expert with regards to the older DMK21-


AND NOTE: Set the camera to 30 FPS mode in IC Capture. Do not use the 60 FPS mode to avoide camera circular artifacts.
