Having been seriously impressed with this image of the prominence the other day acquired with a Lunt LS152
I thought I would have another go at processing my window-sill image. I screwed down the alignment box size (in Registax 6) to 10 pixels and limited the processing to the prominence area. I then added a bit of Lucy-Richardson sharpening in GIMP. I think the extra aperture of the LS152 allows a much faster shutter speed, limiting the blur due to atmospheric wobble. The result is below.
Not as good as the LS152, of course.
There is also the small matter of a factor of 20-30 in the price of the optics of course – – – – Sigh!
