NGC 4449 HaLRGB

NGC4449 is similar to the LMC in size and composition. Supposedly there is a large envelope around this galaxy that extends more than twice its diameter away from the part we see. I caught hints of it, but I think a dark site is needed to pick it up decently. I was amazed at the level of structural detail in such a fairly small target. As is typical variable conditions dominated this shoot--wind being the primary issue. Due to seeing, wind and high cloud, which effected guiding, I could not do better than an average of a FWHM of about 2.5 for L, G, and B. The red channel was a whopping 2.85--by far the worst channel. This is a target that really benefits from good seeing, as there are many structures in the galaxy that when portrayed under poor conditions, look muddy I really wanted to add Ha, but I ran out of clear sky. I will add Ha to finish the image. I know there is a lot of Ha and am looking forward to collecting it.

I added 3.5 hours of Ha. Would have ha 5.5 hours but the wind blew the scope off the guide star

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.
