Mars 127mm Mak

[Bobby1970]

Had a go at this last night. Captured around 5000 frames with the ZWO 178MC and a 2x barlow

Processed the best 50%  using PIPP, AS3 and Registax. 

Can anyone help to explain why it seems like i have a sort of "double" edge to the planet, mainly on the right hand side?? 

Thanks for looking anyway

Some nice detail visible there. The "double image" i think is what is known as the "edge rind artefact" i think its common in a lot of Mars images. A combination of a few things and not easy to remove/hide.

Thanks for the info Pete.

I have noticed it in Venus images i have captured previously and have wondered what it may be, but it seems more pronounced in the Mars image. 

For a pretty small planetary scope i can't grumble too much.
