NGC 2403

NGC 2403 is a relatively bright and large galaxy in Camelopardalis and circumpolar on my site.

On this very cold night I tested with it both the new Focus Craft from APT and the new Multi Star Guiding in PHD2.

As a result I can say that the latter works perfectly and is a gamechanger for me. I am very susceptible to seeing and wind with my small guidescope with short FL on my large Newtonian, but my RMS has decreased by about 50%, which is a lot.

The focusing of the APT compared to the good old Bathinov mask (for which I have to leave the warmth of my couch/bed) seemed good at first and I repeated it a few times for testing purposes. But as the night went on, I noticed that I was a little off the sweet spot when looking at the stars. But the wind also picked up a tiny bit, so that could be the cause as well.

Anyway, with only 100 minutes of exposure time and my famous "5-minute post-processing", I'm happy with the result and this wonderful object that could maybe use a few more Ha data, I think.

Feel free to leave a comment and have a great and healthy time out there!

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.
