Very good for a first attempt, shows Syrtis Major quite nicely.

Very nice,

Much better than my first try

P.S.

Try to crop frames with PIPP before stacking.

Or even better, next time do imaging with ROI (Region of Interest) enabled if cam allows.

For a 1st try that is very good. 👍🏻👍🏻👍🏻

with ROI enabled, you can actually image just around the Planet, as you do not need all the black area around.
It will save much time for processing and etc, plus will enable to do MORE subs per sec. and you want as MUCH subs per sec as Possible.
As per other settings, - keep and eye on the Hystogram, it should be somethere around middle or "middle/slight right" , in other words 50%-70%, -  with as short exposures as you can.
Try different gains, max or Unity, no use to go for 0 gain.

Nothing wrong with that, i find that with planetary imaging every attempt is my first 😂

[ONIKKINEN]

Thats a nice Mars.

You could image for a lot longer, and with a smaller ROI. That will also pump up your framerates and give you loads of frames.

With 320x240 and 4ms exposures youll be racking 100k frames quite fast so might be worth trying that next time. Not sure what the lowest useful exposure time is though, often have read that 5ms is the seeing limit.

[Cosmic Geoff]

The number of frames is OK. You could reduce the ROI and try increasing the gain - I don't know if 76 is high or low for that camera. 

With my ASI462MC and the smallest ROI, the exposure time is sub 1 ms on Mars. 

The details of how you do the processing make a lot of difference.

Much more contrast!

completely forgot, - try to apply Drizzle x2 or x3 while stacking.  You will end up with larger Final image

Could be worth a try, but i am doubtful in this case since the image is already around the size it would need to be if all the available detail were resolved. Drizzling a properly sampled/oversampled image will just result in a bigger blurry image, but no more detail.

you are a planetary imager, of course you are not happy 🙂  It is a very nice start though, not being truly happy is what drives us on to keep capturing.
