Revision title: NGC 4449, The Box Galaxy - Star Correction

After seeing Gary Imm's great work imaging without a focal reducer on his C11 I decided to give my 6SE a shot without the reducer. Previous attempts without the reducer did not go so well but my image acquisition and processing skills have improved since the last effort.

Overall, I think it went well. The stars seem to be better defined without the reducer. I did end up with a bigger crop than I wanted but this was a result of the target not staying centered as I advanced through my filter changes. I'm part of the ASIAIR beta test team and suspect I might have found a software bug. While frustrating in the short term, I really enjoy helping test the new features as I am a huge fan of the ZWO product portfolio. Based upon this encouraging result, I think I will continue without the reducer for the time being.

Description: Slight reprocess that cropped out 2 large obnoxiously oblong stars. In addition, I applied a Photoshop offset filter technique to try and tighten up the star shapes a bit.

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.
