Concentric rings

#1

Post by Ammo Al »

Hello , I have just started using a Svbony 205 for planetary imaging . When i process the video through Astrostackkert or Registax 6 i get concentric rings appear on the planetary image . At first i thought it was the Barlow lens but this happens without it . Any suggestions would be appreciated . Alan

Hi,

I think the effect is know as 'onion rings' (unfortunately not the tasty fried snack version). If you search for 'planetary imaging onion rings' then you will find lots of discussions of the same problem, along with (hopefully) some useful suggestions to fix the issue.

cheers,

Robin
