G'Day from Down Under,

 

I recently decided to shoot the moon but with a different approach. I hadn't read about this or even know if it works but thought I would have a go.

 

What my theory involved was taking a bunch of full frame images of the moon and NOT use lucky imaging.

 

I took the images @ 10ms

 

100 frames

 

Using Celestron 8in Edge HD

 

ASI Air (set to Lunar tracking)

 

EQ6r-Pro

 

The image enclosed is unprocessed but how it came out after processing with Autostakkert. I only used 26 frames although all but one of the frames were very good quality.  I also tried various number of frames ranging from 7 to 50 but got similar results as indicated. 

 

The image below has not had any processing except from Auststakkert so anticipate better results on the surface.  Its the big "Smile" that is the issue and destroys the frame.

 

Love to have some feedback on what I have done wrong or perhaps what to try to get the benefit of stacking.

 

Thanks in advance.

The initial alignment is failing -  are you using 'surface' mode? Planetary mode will fail, often like this.

Two thoughts. One, what happylimpet suggested; make sure you are using Surface alignment and not Planet. If you are using Surface alignment already and still getting this, switch to Global instead of Local under Quality Estimator (you will have to turn Automatic off).

 

Also, you said all but one frame were very high quality. Well, delete the one bad frame. There's no reason to keep it. Either don't load it if you shot stills, or if you shot a SER file, scrub through until you are on the frame and hit the spacebar to exclude it, then reanalyze.

Hey Boro and Happy,

 

Thanks for your thoughts. I will act on your suggestions next opportunity I have - hopefully tonight.  The files were all FIT's files, 55Mb images for each frame.  I thought this may have been the issue.

 

The frame that was horrible has been deleted and was deleted during the processing. I will also change to Global, I think I remember where that is having stared through everything over the weekend.

 

I will report my findings back so that I can leave a trail for the next person who may have the same issue.

 

 

 

Many thanks
