Here is another stab at Mars from the window-sill.
This time the configuration is with an Altair ADC between the X3 barlow and the camera. The extra spacing involved turns the X3 into X5-ish.
I had to “wring its neck” processing-wise to see any detail, but of course you have to bear in mind that it is only a lowly ST-80 through the double glazing!
Still, I fancy that some of the detail is real if you compare it to the Stellarium snapshot, and also with the splendid images here http://spaceweathergallery.com/indiv_upload.php?upload_id=146775&PHPSESSID=dgfiuql6dlb877kjt1fkbn4in4
All the images are rotated to put the S pole at the bottom.
Must get out more!
