Mars, 9th September 2020

Hi all. This is a product my first imaging session for a very long while, and my first attempt at Mars this season.

Captured at about 2:30 BST, 9th September. Omegon RC8, 3x Televue Barlow, ZWO ASI 290MM Mini Mono camera. c. 10,000 frames per channel

I used an IR pass filter for the red channel. It brought out quite a bit of detail, but it caused an 'onion ring' effect  which I recall often happens when imaging Jupiter. Is that something to do with the gain settings or under-exposure or something?

Anyway, I think you can make out Olympus Mons top right and possibly some bright clouds associated with Arsia Mons below it.

Very nice, some good details coming through.

Very good. Love the blue colour of the North Polar Hood.
