M33 (Tom Gray) - AstroBin

M33

This image of M33 in Triangulum was taken at the native focal length 545mm f6.8 pushing my tiny Star Adventurer mount to its limits. As I eluded to in my last post my dew control system failed, literally blowing a fuse, and I had to resort to a little 12v hair drier that I keep for just such eventualities. Comprising 3 min exposures, I managed 52 subs which I calibrated, stacked and processed entirely in Astro Pixel Processor - I am impressed with this program. I also took a few 10 min subs, at the end of the run, and was amazed that the Star Adventurer with RA guiding only, produced a very reasonable image (see revision).

M33 does not always give up its structure and detail easily, and can be quite bland - see my previous posts of this object. I am much happier with the level of saturation and detail in this image. After the Milky Way and Andromeda galaxies, this is the third member of our local group, lying 2.7m LY from earth, and containing around 40 billion stars, it should be easily visible with the naked eye from a Bortle 2 site, and I have witnessed this many times. This year, I had difficulty making it out - either due to the amount of water vapour in the air, increasing light pollution, or my deteriorating eyesight - probably all three!

It is peppered with nebulae and bright star clouds - active star forming regions, and some of these are annotated in the plate solve. I think it is far from bland and makes for an interesting target, if quite challenging to process. I hope you like my latest version.

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.
