CTA 1 - A supernova remnant in Cepheus and its little friend NGC 40.

I knew I would get a lot of clear nights during this time of year and I wanted to do something very rare. I had never seen this before and when my friend Reg showed it to me, I had to frame it up. I knew it would be a hard one considering how faint it appears in most images. It was definitely a challenge to process. I would like to find someone better than me to give it a go someday.

I have to say, the best purchase I've made in all of this hobby is the moonlite nitecrawler. Framing stuff and keeping it consistent night after night has really opened up another level for me.
Another great purchase has been the Esprit 120. I had a Tak120 a couple years ago but I never did care for it, I was solely interested in small targets. FFWD to 2023 and this telescope is a beauty. It's rivals anything I've used to far and I've owned around 16 telescopes.

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.
