1st time out in weeks: Mars 15th April

Couldn't resist the clear skies here last night, here are a few Mars edits - very pleased with the results having never imaged Mars before!

Equipment: SW 180pro Mak, 2x Barlow (would a 2.5x or 3x be worth getting, or would that be pushing the scope too far?), ASI120MC.

Processing: AS!2 (4000-5000 frames for these images), Registax 6 for wavelets, Photoshop elements for final levels

The first 3 have been enlarged to 150%, the last one is original size to show what I'm getting directly from the camera & 2x barlow.

Thanks oldpink, yeah I think a 3x Barlow may be on order very soon - I wasn't sure how far you could push the magnification before the image gets too 'dark' to be usable without negatively affecting exposure time & frame rate. The 180 mak is f15, so a 3x barlow would make it f45 (that's my understanding, correct me if I'm wrong!) which sounds quite high to me! What do people get away with for Mars?

Nice image, quite similar to the one I shot at F/30 (TeleXtender) in my C8 with an ASI120MC. I think yours are a touch sharper (but I might tweak the processing a bit, to extract more)

I have seen some really nice shots at F/40 with the ASI120 and a C9.25, so longer F-ratios can work
