NGC 5746

Here we have my crack at NGC5746, a very beautiful nearly edge-on spiral galaxy in Virgo. The galaxy lies somewhere between 78 and 98 million light years away. The galaxy has an apparent diameter of about 7.4 arcmin. The NASA/IPAC Extragalactic Database shows a diameter of about 194,000 light years which makes it a pretty big galaxy.

I imaged this over several nights and decided to try to do a little bit of a HDR type of process on the luminance capture. I wanted to try to pull a little bit of detail out of the disk which I thought might be somewhat similar to what can be done with M104. That seemed to work pretty well although I am now wondering if drizzling might help achieve more detail.

Also had to throw away a whole 5-hours of additional L data because somehow, I lost my collimation. A mystery to me still, lol...

Processing was not difficult, my goals were to bring out some detail in the galactic disk and capture as much of the tiny background galaxies as I could and not worry about the size of the stars that oversaturated. Interesting how many tiny galaxies are in the field that do not even appear to have PGC designations.

Anyway, a fun project I hope you like it! Comments/criticism always welcome...

CS and good health!

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.
