Issues with dark spots in a Lunar on Ver. 1.5

Post by Troy Galebach »

I recently upgraded to StarTools Ver. 1.5. I decided to take a file I had processed on Ver. 1.4 just to see what might be new and improved under Ver. 1.5.
I had unsatisfactory results in a near full moon image I had successfully processed under Ver. 1.4. I ended up with dark spots in the center of the image.
I've tried different settings, and still have those dark spots. See the maria in the center and a bit to the right in the image.

Looking for some guidance if someone would be so kind. I'm uploading the image I processed, any ideas?
I've tried all sorts of Development settings, and Auto develop. I still have the spots.
Any suggestions would be appreciated.

Hi Troy,

Would you be able to circle the problematic areas in the image? I cannot see anything particularly problematic...
The darkening of the maria in places constitutes real lunar features and can be corroborated in many other images.
For example this image from Wikipedia.
Am I missing something?

Ivo,
I don't know if you recall, but I'm the guy who had a stroke last year. Thank you for your reply, I believe that the dark spots on the maria is something I forgot.
In essence you were quite right. I am sorry to have troubled you with the non-issue. I don't get out much, but I do enjoy it when I can, and I've told a few folks about StarTools on Twitter, and included it as a recommendation on my website.
Hope all is well, I'm looking forward to fall, and getting some stable weather so I can do some Deep Sky captures. I had the 5 inch refractor out the other night and it was very bad seeing. I could see Saturn wavering on the Camera monitoring screen. I got a sad image of Saturn, but hey I was out with my toys and captured Saturn. Thanks again for the great processing tool Ivo.

I've included my sad image, but I'll do better when I can get the 7 inch Mak out with a 3x barlow.
This was with the refractor with a 2x barlow.

No problem at all Troy - any question is welcome, and good to hear you're back in the saddle!

We don't all have the luxury to wait for (or drive to) pristine moon-less skies with perfect seeing conditions, so I'm a firm believer in "taking what you can get" and making the best of it.
Looks like you're doing just that. :thumbsup:

Clear skies!
