Mars is now getting close enough that those of us with smaller aperture scopes can capture interesting images. Therefore, this seems like a good time to start a small-bore Mars challenge to run alongside those we already have for Jupiter, Saturn and the Moon. So please share your images of Mars captured with apertures of 6" or less here!
For those of us in the temperate parts of northern hemisphere, Mars is particularly challenging given its low elevation. Mars currently transits at about 21° above the horizon where I live, and it will remain close to that around opposition. Nevertheless, on good nights I can now make out surface features at the eyepiece, and capture even more detail when imaging. Here is my most recent Mars image from this morning (April 16 2016), captured with my new ASI224MC camera and a Nexstar 6SE with 2x Barlow. For this I captured 3 avis of 30 000 frames (average 157 fps) and combined the resulting stacked images from AS!2 in WinJUPOS after sharpening in Registax. A little additional processing was done in Photoshop (sharpening/blurring, colour balance). Nice to see clear views of Syrtis Major and the cloud in Hellas Basin.
I'm still getting the hang of processing captures from this camera, so I'd welcome any tips that might improve my Mars images.
I look forward to seeing what other small-scope users are capturing!
