This exposure with the ED telescope is one quarter the length of the image with the standard achromat, so a direct comparison is not appropriate.

Hi Peter,

Your new scope is looking great and performing superbly.

I think your jewels have a dose of the magentas. It is a problem I often have with the stars using a DSLR but have recently found a neat trick to fix it in pixinsight. On the colour image use process - invert, then process - scnr green at 100 percent. Then invert back again. There is probably a similar way to do it in Photoshop but I am not fluent in that language.

Best regards, Graham
