M67/NGC 2682 - LRGB

Dear friends (and S.M.),

What does one get when imaging an open star cluster with really good seeing (FWHM=1.52")? Here is an example:

There is a slight problem with the green channel and a very slight gradient which I must resolve.

I hope you like it.

Can you elaborate on this green gradient you mention, I don't see what you're talking about.
BTW, this is a really stunning image

Hehehehe ... thanks.

Actually I am glad you do not see it ... please look VERY carefully horizontally along the bottom of the image.

BTW, this is a really stunning image

This is my second stab at M67. The first was based on the luminance layer having 3-min subs whereas this effort has 6-min subs and I can see a dramatic difference.

Thanks for the feedback.

Super image Anthony!
The green didn't become apparent until I opened the full image. Even then, it's only barely noticeable. Seems slightly more prominent in the outer fringes of the image than in the centre. Looking at the levels of the channels, I noticed that the red and blue channels are clipped a little more than the green.

BTW, is that a full frame image or have you scaled/cropped the image from the original size?

Hi Michael,

I purposely clipped the red and blue so as to minimize the offending green channel. It was a little bit worse before I purposely clipped.
