The image comparison above is from an image you posted here from one of our previous conversations:Roger, before I even get into this with you, I don't know what you are trying to pull, but you seem to have purposely butchered my image in the comparison with yours. Whatever you did to make that comparison look that bad is completely unethical. THIS is how my image really looks:
Rogers image in comparison to a butchered version of my own!! WTF?
I am not even going to begin having a conversation with you about this if you are going to screw around with my image like that, and try to purposely present it in an unreal and unfair light. That is beyond screwed up!
And again, you are SIGNIFICANTLY downsampling the data here, which is hiding the true nature of the noise in your image. I've shared my image at 100% crop, so there is no additional smoothing of noise due to downsampling. I am not even going to touch your image to provide my own comparison after this, though...good god.
Canon 60Da or 'full frame' better for astrophotography?
I'm sure I'll get flamed now.... No flame, but your reviews are always strictly Canon centric. Where's a review for the Nikon D5100, D5300, Sony A7s, etc. ?? Sorry, my bad here due to the fact my opening question being about Canon equipment as that is what i have and was not aware of other...
The area in the comparison is from the upper right. A simple curves stretch shows the mottling on your posted image. Glad to see you've improved and reduced the mottling with more recent processing.
Roger
