M33 Triangulum in a square

If you're reading this, thank you for having a look! This is really the first light with my new Rokinon 135mm. The lens is wonderful for the price but comes with some flaws, especially wide open. Even more so when magnified here with a 2x converter. I had to stop down to f2.8 to dial in the stars and eliminate some spherical aberration, leaving me at f5.6. But it was still tough for me using the asi294mm as there was still slight tilt. Using a tilt corrector helped but the stars still suffered from some coma outside the center and color fringing. Which, on a small sensor like that shouldn't happen. I think using the lens straight would have been fine, but I wanted to grab that wider field of the galaxy and at 135mm it was just too wide. The luminosity is captured separately with the SW100 which to my taste is just a little too tight a field. Using the 2 optics kinda solves the problem.

I also tried Lucky Imaging to collect some L data but failed miserably. If someone knows how to capture that, please point me in the right direction. I tried video frames and about 7000 calibrated light frames but I just think my imaging train may have been too slow.

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.
