M97 The Owl Nebula

I shot the Owl Nebula a while back with a DSLR and wanted to try it again with my mono CCD. This was taken over about a 2 week period when I was experimenting leaving my equipment out under some Telegizmo covers. The scope was on a concrete pool deck so it would not shift night to night, and it is not warm enough in the day yet to heat the concrete up to cause different problems. I have both the tripod and scope 365 covers for a nice complete package.

This allowed me to focus more on imaging rather than set up and tear down. I was amazed at how well the system took 10 minute subs, which gave me much more signal to work with and made processing easier.

I think that capturing the outer ring of the Owl in Bortle 8 is a real achievement for me. Its faint, but it is there!

I hope you like it!

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.
