NGC4565 with NGC4562 imaged on Mar 20, 21 and Apr 1, 2021 UTC through a 200 mm aperture, 730 mm focal length F/3.65 Boren-Simon PowerNewton Astrograph with 0.73x focal reducer and coma corrector. The imaging camera was a QSI683wsg-8 with Astrodon II filters and cooled to -15C, with off-axis guiding. The system was mounted on a Losmandy G11G2 equatorial head on a permanent pier. The system was controlled with Sequence Generator Pro and PHD2 and the image was processed in PixInsight.
11 Luminance frames x 10 min binned 1x1 and 7 RGB frames x 10 minutes each binned 2x2 for a total exposure of 3 hours 35 minutes. 16 flats, bias and darks frames.
In this cropped image, you can see the yellow central stars and blue regions of new star formation. Also, notice the slightly warped disk.
