This was the first light with the EQ8 mount. Guiding went pretty well.

I did not do any real image processing with this image, which was more of a guiding test.

The small galaxy to the lower left is IC4617, a 15,2 magnitude sprial galaxy of 1.2 x 0.4 arcmin at a whopping distance of 500 million light years. Not to be confused with NGC 6207 the 11.3 magnitude galaxy that is just outside the frame even more lower left. Usually that latter one is the 'famous' galaxy close to the also famous Hercules cluster.

Description: Actually an image of the next night, with some frames from May 25th. I reworked the OAG connection screws so that the sensor would be as square as possible to the optical axis. The shadow of the OAG prism on the lower left corner.

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.
