What a Saturn!

Your image definitely makes me thinking to exchange my vintage C8 for a C9.25...

Thanks for posting.

 

Best wishes

Four thoughts:

  1. Excellent detail on the polar hexagon.
  2. Great contrast and detail on the rings.
  3. The Crepe ring is missing.
  4. The rings look lavender to me (RGB = [185, 186, 239]).

Everyone's a critic…

Would that make you a...Crepe-ic? *Bad dum tiss!*

 

First, I ran it through Image analyzer, better now?

Is it supposed to be visible in a 9.25?

Thank you kindly

A solid attempt!

 

The ota is very good. Camera is good, but upping to the 224 or 290 will present a better step up.  Are you barlowed?

 

Stacking in autostakkert and wavelets in registax might give you a far better result

Looking at selling my GPS 11 to get a MUCH better camera.   want to be able to do DSO's as well.

This was Un-barlowed, have a 2x on the way.

Unfortunately for me there is no club near by, so this has been a learn by mistake venture.

The finding an object and tracking is the easy part.  The software is not.

I have tried I-cap, Fire Capture, and Sharp cap.

I used sharp cap for this image.  

I do not have Photo shop or any other post processing image enhancing program as of yet.  

Do to the location of my back deck and the trees, I only have about 1 hour to image Saturn in, and each day that time gets shorter.  Unless someone knocks down some trees.

Yes I do.  BUT !!!!

it is not the easiest thing to set up align and balance.  By the time you add a guide scope/camera, and all the other nice things, it is pushing the limits of the mount.

Still a bit of weird color in the rings - I believe they should be essentially color-less.  From my kind of latitude, I could expect/explain that.  You have little excuse so far south :)

 

Seriously though - nice!

Im in Michigan.  

Most of the lack of quality is due to operator error. 10% poor camera.

The denoise color artifact could be a leftover of sharpening.

Ha! Probably.

 

Your new pic has no red in the A rings, but the B ring still looks lavender (RGB = [189, 188, 230]) to me, so a little heavy on the blue at the top. Note that Saturn's rings are not colorless…Cassini says they're pinkish-yellow (RGB = [235, 220, 212]), so a little heavy on the red and lightest on the blue at the top.

 

The crepe ring is visible through the eyepiece in good seeing, so the camera picks it up. If I increase the gamma of your image, it shows up. All sharpening methods increase contrast by moving pixels away from some seemingly arbitrary brightness midtone. If the crepe ring was below that when you started, it would have been squashed into the darker tones.

It looks like you need to use an IR cut filter, because the color balance is off. Otherwise the second  image looks very good.
