Imaging Mars

[DaveHKent]

I had a go at imaging Mars on Sunday night. No cloud but high humidity (I could see a triangle of light coming down from a nearby street light, which is my usual judge of conditions).

Any advice on the following image? I decided to do a mosaic of a raw frame->stacked->sharpened then reduced to normal size again. Did I sharpen it too much? The image increases in size, as I used "Drizzle 3.0x".

Kit & process: Celestron Nexstar 90 SLT (90mm scope), ZWO ASI120MC, SharpCap. Processed in AutoStakkert, taking the best 40%. Sharpened in RegiStax.

I did struggle with the focus. Being so small on screen and wobbling due to atmosphere, I could not get anything I thought was crisp. In the end, I opted for the spot in the middle of two points I could clearly tell were out of focus.

Sorry no advice, but very nice images.

To my eye, best image is one to the right.

I don't like enlarged images that are soft - obviously missing resolution. I prefer smaller image, but one that looks properly sampled. If scope can't deliver more detail - why force it.

90mm won't make very large image, but what it renders - renders very nicely. I would not mind having a look at mars resembling image to the right out of these four.

Following with interest - I’m planning on a night with Mars Thursday night - intending to try my 600d via APT
