Jupiter and Saturn via C8, 3 October 2019

I'm so confused! While I had a reasonable color balance in SharpCap during capture, these images turned out bluish-purple. I blamed it on the scope.

I captured these planets immediately after gathering frames for a 3-panel lunar mosaic using a 2x barlow lens and my ASI174MC cam, my buddy Tyler's C8, all riding atop my AVX mount.

Anyway, the confusing part for me is the Bayer matrix on the 174. Per the ZWO website, it should be GBRG. And in Autostakker!, using GBRG to debayer works well some of the time. And then I get something spit out that looks terrible or shows the Bayer pattern when wavelets are applied. Back to Autostakkert, I can force RGGB and the image turns out great. Go figure.

When I first processed these two images, I still had Autostakkert configured to force RGGB. That's when I got my purple images. After thinking about that for a few days, I went back to Autostakkert and set it to "auto" for the Bayer detection. This time Autostakkert said BGGR was the correct one to use. So now we are up to 3 different debayer plans for this camera. What the heck, man?

Oh well. The color looks normal this time. Beats the dog crap out of me why it does that.

Nice images here Bryan.

The mystery of how these programs works is...a mystery.

Well heck, as long as it come out in the end.
Thank you Bryan

Thanks, Mark!

I just noticed there are a couple of moons in the Jupiter image (to the left and right) if you look at it sideways.

Yuppers !
I did notice that.
That is a triumph in itself!
And I did not have to use averted vision to see them!

Very nice images Bryan. How many frames did you capture and what percentage of those frames did you use?

Just curious,
JT

[OhNo]

Almost seems as if the focus is a little soft.

It is. I have quite got the knack for focusing this scope yet.

Thanks, JT. 1000 frames, and 10%.

That’s some really cool stuff!

Pretty cool you exchanged scopes and can get to mess with the C8. Must be a whole different world!

Those are really cool images. I especially like Saturn. To me, Saturn is one of the most striking objects in the night sky.

Great images Bryan!

Thanks,
Jim

Thanks, Jim! It is indeed fun to get to try out some new gear.

Oops. Here is another Jupiter capture from the same evening. For some reason I did not crank the video through. I think my initial purple-blue discouraged me and I didn't bother. A bit shorter on the exposure with this one.

Here is a shot via my C6-R back at the end of July using my ASI120MM-S and a 3x focal extender.

If the sky will cooperate, I would like to do a comparison with the C8, C6-R, and SV102T all using the same cam and configured for similar focal lengths (well, as near as I can get them).
