NGC 4565 - ‘on edge’

I wanted to revisit this wonderful edge on spiral at f6.3 in my 8” SCT to try and pull out a bit more detail in the core and add some colour. Atmospheric stability had definitely deteriorated from the previous evening, with a HFD ~5, and my autoguider was fighting the poor seeing with RMS ~1.5. I had to throw away over half the luminance frames due to atmospheric distortion, despite the focus being OK, and my colour frames were a ‘washout’, possibly due to a filter slide not being fully closed, resulting in some light ingress. I quite like the image scale, but sadly no more detail, and posted really as a reminder to self that some clear, dark nights are just not suitable.

Fortunately, I consider Astrobin as a bit of an art (and science) community, where anything much goes and we can share and learn from our successes and mistakes, whilst we improve our skills and processes. If you are after a high end gallery, then there are plenty of those to choose from as well. I try not to get too uptight or ‘on edge’ about these things, as long as we are all having some fun.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
