Sunspot 26/7/2020 @ 09:30, Lichfield

After a long hiatus with no sunspots, there is one at last.

Battling against a lot of cloud, I managed to get a few seconds of precious video in (about the only) clear spot there was and processed it to get the image below.

The photo suggests that my Quark is not quite flat to the image plain – I am not sure if this is the focuser or the Quark etalon itself – I do have a tilt adapter but today was set to 0 degrees.

Can anyone tell me which from the photo?

I then ran the above image through PixInisght’s deconvolusion routine to produce following. Which do you prefer? Let me know!

Do you think the image created from 39 frames or 166 frames is better? Although more frames potentially could give more detail it also can potentially add more blur as using lower quality images in the stack.

Jupiter from last night

My best ever image of Jupiter – although there is colour data here I can’t work out how to show it!

Can anyone help?

Difference between image 1 and 2 is that levels tweaked on 1 compared to 2.

I tried to bring out the colour in following – I have a lot to learn about image processing!
