Last year I put up an image of NGC2070 and received much useful advice from many members.I have received much guidance from another local astrogazer.


This image was again taken with a Canon 60Da at prime focus of my Mewlon 210.
The guiding received attention, now off axis
The mount has been upgraded
The acquisition was controlled by Nebulosity3
10 of 650 second frames at ISO 400 with 2X2 software binning
Ten dark frames were taken with the same settings


Processing was with Nebulosity 3
The darks were stacked to make a master dark which was used in Neb3 for pre-processing., The best 6 images were stacked. Curves were used to stretch the bottom of the data and reduce the saturation of the central star in the nebula.


What next? Any comments/criticism would be appreciated.

Well it looks like a wonderful image to me.
I think you can be proud of your result.
Just keep doing more you seem to be on the right track.

Very good, lots of details...
However, coma is pretty obvious, especially in corners...

Looks very good Chris. Good resolution and colors. :thumbsup:
You won't get a full corrected field with the Mewlon 210 on a largish sensor.
That's why I swapped mine for the CN-212. There is a corrector available for it but it's quite costly.

You’ve resolved the R136 very well! Well done with 11 minute exposures at the long focal length :thumbsup:

Startools "Lens" module will help correct it....well not correct it, but modify the picture to make it more acceptable

For sure you can fix a lot in processing but getting the data as close as you can makes it a lot easier.
