My Mars Show & Tell

JohnH, here is my best effort from last night. First time imaging Mars for me too.

Shot with a 10" LX200 GPS with a 2x barlow.

As far as improving your imaging there are a couple of things I know I need to do - you may be in the same boat.

First - I focus by looking at the image on the laptop screen. To achieve better focus I am going to build a Hartmann mask (see Projects & DIY section). This lets you focus on a star before swinging over to Mars.

Second - Collimation. I think my collimation is pretty good but I know it can be a lot better. Practice makes perfect!

Last - Seeing - can't do too much about this except making sure you site your telescope at the best place. My images last night were taken looking over my garage roof. This roof is colorbond so it still radiates heat into the night. I suppose if the seeing is not good then I shouldn't bother imaging.

Good Luck!
