21 Oct 2021 - Jupiter through various filters & then an attempted recombination

Hello,

I managed to grab some data on Jupiter last week.  I bore in mind @Nik271 advice on an earlier attempt to keep a ratio of 4-5x between the f-ratio and the pixel size.  So this time I used the f/10 Mak with an ASI290MM (2.9um pixel size so at 3.4x still not quite in the 4-5x range).  And having got my hands on a manual FW from another kind SGLer, tried a bunch of old Meade 4000 filters & then a combination in GIMP.

The filters used were ND96, 23A (light red?), 58 (green), 80A (blue) & 12 (yellow).

The image from each of the filters is below (its interesting seeing the differences in what data comes through), as is an attempt at combining the RGB images into a colour (w a bit of playing around in GIMP).

I suppose its a start although still well away from the calibre of the other images on here!

Cheers,

Vin

Nice images. It's interesting that the Green filter appears to show the most contrast. I've used Yellow and Blue filters for viewing Jupiter before, maybe I will stack them to try viewing through Green! 👍

Thanks - you should report back what you find!

Also on closer inspection, I notice that the images are slightly different quality outputs from ImPPG.  I used the same settings on each, but maybe I should tailor it to each image & then recombine.  Lets see.
