I finally had the chance to image my favorite galaxy for the first time! I fell in love with the Sombrero Galaxy when I saw it through my first telescope back in 2017. This was a bit of a stinker to image though.

I used two cameras and two telescopes to image it. The first set of data came from my Hyperstar setup with my ASI533mc Pro camera. But I wasn't real pleased with the image because that setup has a pixel scale of 1.44" which doesn't do too well with small galaxies and the seeing wasn't great that night either. A few weeks later, I setup my 4.5" refractor with my ASI183mm Pro and a luminance filter. The seeing was better, the pixel scale was 0.77" and my refractor has always given me sharper images than my SCT/Hyperstar rig, so the data was much crisper. I combined the RGB and Lum data sets with different pixel scales using Pixinsight's Dynamic Alignment process. This was the first time I've ever done anything like this, but it worked out really well! I could have used my LRGB filters with with the ASI183mm instead doing it the way I did, but using the OSC camera with the Hyperstar at f2.3 allowed me to gather the RGB data much faster.

There's also a link below the image to my YouTube video about imaging this galaxy if you're interested in watching.

Clear Skies,

Daniel

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.
