Revision title: Leo Triplet M65, M66 and NGC3628 -> new edit

While fighting with my Newton and its problems, I set up my widefield rig to get some results to keep me motivated. But there seems to be not much interesting targets for my taste in the period of the next weeks or months. So I decided to think a bit more like the common photographers and use the widefield views as tool for interesting compositions. Sadly, my current view is limited to about one half of the sky. Also the milky way is currently trapped in the light pollution of my home town. So taking long LRGB or HSO exposures is a bit difficult for my taste. I am not in a big city, so this is complaining on a high level.

Before choosing extraordinary compositions, I had to find an optimum exposure time for some of the basic stuff. I decided to use the Leo Triplet as test subject. This image is the result. As usual, I overshoot with exposure times of 5min per frame. But thats ok. The result is quite ok. Next time, I will reduce the exposure time to 180s or less. This should also work with my ASI183MM camera.

There's more to come...

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.
