NGC3718/Arp214

I didn't realise when I started to capture this image just how beautiful and interesting it is, neither did I realise just how hard it would be with my skill set to process.

I had to throw away about 3.5 hours of Lum data due to some horrible artefacts which my flats wouldn't remove.

I don't think I have ever spent so much time on a subject, it really has challenged me with the processing as well.

We had an unusual clear spell which allowed me over a period of a few weeks to get enough data, but then I was getting problems with hot pixels which was finally resolved by Rob on the PI forum, turns out the rejection algorithm wasn't doing what I had hoped it would.

I've learnt even more new techniques, and I enjoyed the challenge.

Here's the Bumf: -

NGC 3718, also called Arp 214, is a galaxy located approximately 52 million light years from Earth in the constellation Ursa Major. It is either a lenticular or spiral galaxy.

NGC 3718 has a warped, s-shape. This may be due to gravitational interaction between it and NGC 3729, another spiral galaxy located 150,000 light-years away.

NGC 3718 is a member of the Ursa Major Cluster.

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.
