NGC6543 The Cats Eye Nebula

I may try and improve this image when the moon is out of the way and it cools down. There is too much noise and I don't like the centre. I have used flexure for a long time as a substitute for dithering which was impossible for me with my MGEN3 guider into Sharpcap. This time I got caught out with walking noise which looked like rain and it's horrible! I have now got used to PHD2 guiding and the scheduler in Sharpcap and getting close to making a go of it with NINA so dithering it is from now on. It's a time for testing and more intensive learning. I am also having issues with my coma corrector and I have sorted out a long standing design tilt issue with the Skywatcher focusser which I haven't read about, so that's a relief as it's been a real puzzle. Wouldn't it be nice to sit down with a real expert and ask them how to fix something? Anyway progress is slowly being made and it's only a hobby. That's what I tell myself anyway! To infinity and beyond!!

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.
