M57 w/ Televue 4x powermate
|
Another attempt at M57, again with the powermate to get a reasonable image size.
This one has much better detail with less processing than previous attempts - both inside the ring and outside (like the galaxy in the top left corner)
The focus on the later images is a little soft, suggesting that refocusing (or temperature compensation) is necessary when using the Powermate for extended periods.
For some unknown reason the darks for the RGB images couldn't be properly subtracted, so a 3x3 median filter was used to eliminate the noise pixels.
