Congratulations on a great image of M3, Milby ! :bow::bow:

Try perhaps desaturating it and, using "Levels", move the grey, (middle) slider further to the left a little ? :idea:

You may be surprised. There's more detail still there within the image which you may want to bring out and which will still not over expose the core !

Beautiful work ! :waytogo: !

Best regards,
Tel

Appreciate the input, Tel. As you may recall, I'm on the learning curve with Pixinsight, which is a remarkably deep program but quite different from Photoshop. At present my "issue" with it is achieving good noise reduction without sacrificing data. The fight goes on :o

Looks like you're winning "hands down", Milby ! :bow::bow:

Here's what I meant regarding a desaturation to the original plus a slight shift in "Levels" which I'm sure Pixinsight must equally have on its feature list; (i.e. Levels and Curves).

I don't think this has introduced any noise but has brought out more star details. However, the end result is solely for you alone to judge ! :waytogo:

Keep 'em coming ! :bow:

Best regards,
Tel

Oh, the program can do it, no doubt. It's the user that's the rate-limiting step!

Hi Milby

You have a lot of very good images with the C9.25 Edge and hyperstar! I'm very interested in this setup, what are your impressions?

Best regards

Alfredo

I also wrapped up a second processing video showing how I did the Orion post-processing, to supplement the other video I posted above a while back.

Either, its regard to the gear cogging issues reported on this mount for longer exposures. I was just wondering how many mins exposure you could get before it became an problem.


Hi Jon,

The dec cogging issue with the CGEM has been solved by Celestron with new motor control firmware. I've been part of the beta testing and it is working great now. I've been able to get 10 minute subs - around 12 with no throw-outs, with a 25 lb load. I imagine I could go longer. My DEC RMS guiding has been around .20 pixels, and dec guiding has been better than RA. I've also been imaging with my C8 at 2000mm FL, which I could never do before the fix.

The public release of this fix should be available very soon, days or a couple of weeks at most. In any case, the beta is also available to anyone who signs up at TeamCelestron.com.

I would highly recommend the CGEM now. I have been delighted with it since using the new firmware.

Doug

I thought I would chime in here with an image I posted on the DSLR forum. I did this with 14 x 120s subs with my C11 Hyperstar, Astronomik CLS-CCD filter and my wife's UN-MODDED T2i. A total of 28 whole minutes!

Hi Phil

It is amazing how much Ha can get the unmodified DSLR with hyperstar in just 30 minutes.

What ISO did you use?

Glad you fixed the problems with your hyperstar.

Best regards

Alfredo
