First light Askar FRA300 Pro - IC 1396

This a first light image taken with my new-ish Askar FRA300 Pro which is a 60mm f/5 quintuplet Petzval design. This scope has a nice wide field to showcase larger diameter DSOs. This image was captured with my seldom-used ASI 2600MC OSC camera with a filter drawer and Askar’s 6nm Ha-OIII and SII-OIII duo-narrowband 2-inch filters which worked quite well. The SII-OIII filter did a great job of adding additional OIII data. See revisions for specific filter basic stretch. The RGB was captured with an Optolong L-Pro 2-inch filter. Overall, I really like this setup as it has opened up quite a few additional large targets.

IC 1396 is an ionized gas region located in Cepheus and is about 2400 light years away. The Elephant's Trunk Nebula within IC 1396 is a star forming region containing several young stars discovered in 2003 that are estimated to be less than 100000 years old. The entire IC 1396 region is ionized by the massive star HD 206267. A couple of planetary nebula are shown - on the lower left is Sharpless 128 (Abell 77) and on the right is PK100-04.1. Also on the right side of the nebula is Mu Cepheid - a red supergiant, also known as Herschel’s Garnet Star, is one of the largest known stars with a radius of 1200-1600 times that of the Sun.

Imaged over several nights: Jul 11-12, 17, 26-27; Aug 1, 2023

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.
