NGC 2403 spiral galaxy

The spiral galaxy NGC 2403 is visible in the spring sky in the direction of the constellation Camelopardalis. The object is also known as Caldwell 7. The galaxy, about 10 million light-years away, was first identified by William Herschel in 1788. It is registered as one of the more distant members of the M 81 group.
The image shows the characteristic spiral arms of the galaxy, the shape of which is quite similar to the shape of the spiral arms of the well-known M 33 galaxy.
I took the picture with an APM 1.5x coma-correcting Barlow 2", which increases the original focal length of my telescope of 800 mm to 1200 mm. Unfortunately, this also reduces the brightness of the system from f/4 to f/6. Therefore, the original I wanted to collect much more, but unfortunately only 7 and a half hours of raw material was collected during two outings.

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.
