Messier 3

With an 81% illuminated moon out, I guess I was pushing my luck with taking this object - but then I was not after faint nebulosity, so the affect of the moon was less concerning. I partly imaged last night because I wanted to check the guiding. I have had the Declination graph's line shooting off at weird angles, right off the screen, in PHD, for no apparent reason - so I tightened up the axes because there was some play in them. But then there have been quite gusty winds recently, so maybe it is all to do with that - I really do not know. The scope acts like a bit of a sail in relative winds.

Up close the stars are still not as round as they were the other week and I threw away quite a few subs - either because of cloud cover or because the stars were too misshapen. I am a little stuck at the moment. We will have to see...

I took 25 subs at 4 minutes long each, using my 8" reflector and modified DSLR. I am quite pleased with 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.
