M97 - Owl Nebula - Two Nights - Two Scopes

I have always found M97 a difficult subject and at times I wonder how it could be spotted by Messier and Méchain with their 18th century equipment, sure skies were way darker back then, but nevertheless ... in my opinion even harder than M101.

And I'm talking about how I see them on a screen, with light collected for 20-30s by a high Q.E. CMOS sensor, not by naked eyes.

Anyway, I summed my previous light frames from May 23rd with new pics taken on May 31th with a different scope (Meade 2045D the first time, Bresser 102/460 the second).

There was quite a waxing moon to spoil a bit the second attempt, but in any case I find the result rather shoddy, compared to what you may obtain with the same exposure on, say, M27 or M57.

Perhaps only M76 is in the same league among Messier objects.

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.
