NGC2207 luminance

Hello all

The attached image is a combination of C14 and RC14 luminance data of NGC2207.

Total integration time is about 3.5hrs with a QHY9 camera + ASI 120MM + OAG on an EQ8.

The C14 data was taken last year in conditions of very good seeing with the 2hr stack showing FWHM's of 1.7"
Unfortunately, the data from last night with the RC14 was not as good, with the seeing briefly at 1.9", but then worsening quickly to 2.5" - 3" for the rest of the session.

The wider FOV is about 70% of the total field reduced for display.
The narrower FOV is a crop of about 25% of the image at full resolution.

Cheers
Maurice
