This was taken on 10/6/2020 as Mars made its closest pass by earth for the next 15 years.
I had this telescope for three years. I got caught up in the aperture fever. I could never get it collimated right. The week before I said I'm going to get this once and for all. I finally did it and this was my reward.

Celestron 11" HD on a CGX Celestron mount. Camera used was a ZWO ASI290MC
lap top to capture the images.

Three minute exposure
Pipp software program, to control the jumping around of Mars.
AutoStakkert to stack the images.
Registax for wave lengths
Photoshop and used Topaz stabilizer.
I hope this information will be helpful to someone just starting out.
