M94 - The Cat's Eye Galaxy in Canes Venatici

Here we have a try at M94, a class (R)SA(r)ab, LINER galaxy locatedin Canes Venatici. The galaxy lies about 16 million light years away and has a diameter of about 50,000 light years but the outer ring extends for another 30,000 light years or so. The galaxy contains an estimated 40 billion stars. (messier-objects.com)

I shot this one with a Stellarvue 90mm APO that I have been using and with which I am quite impressed. Of course this would have been a much better subject for the C9.25 which was out of commission for a short period of time. But still, I think the small refractor with a 630mm focal length did a better than expected job of collecting the data.

In processing, I am still working on learning the best ways to use the GHS script and the Vicente Peris continuum subtraction routine. Otherwise, I just wanted to try to let the faint outer ring show as much as possible. Posted with a 2x downsample.

I hope you enjoy this one, Clear Skies 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.
