Well, I begrudgingly paid for a membership. Bugs me a little to have to pay to upload, because we're not getting any new features (yet) but we're having to pay now. I do enjoy having all my images cataloged this way with all the stats, so I opened up my wallet, and here we are.

This object was a real challenge. I've been working on this image all month. Took me the entire month of January.

I started using a new guide scope bracket, and I ended up getting flexure that was causing me to have elongated stars. I never zoomed in close enough to notice that they were bad, so I ended up capturing 35 hours of data that I couldn't use. You just can't imagine how devastated I was to lose all those subs.

So after I realized my mistake and switched back to the metal bracket, I started getting good stars again. So ever since, I've been re-shooting everything I had lost.

This is also the debut image of my new field flattener. Its an FF6 from Stellarvue and the results are amazing! I can now use 100% of the starfield when I do full-image HFR readings on my images in SGP. So my focus should be more accurate now that I can get focus on stars that are not elongated. And of course now I can think about getting into mosaics.

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.
