IC 405 Flaming Star Nebula

This is me sticking my toe into narrowband imaging. I bought a used Orion G3 mono camera, as well as used Ha, OIII, and SII 1.25" filters. This image is Ha only. Star spikes courtesy of Astronomy Tools actions for PS.

The image itself is a portion of IC 405, the Flaming Star nebula. The nebula is an emission/reflection nebula in the constellation Auriga, surrounding the bluish star AE Aurigae. It shines at magnitude +10.0. The nebula measures approximately 37.0' x 19.0', and lies about 1,500 light-years away. [Source: Wikipedia]

The sensor on the G3 camera has just over 2% of the number of pixels as my DSLR, so I am limited to my shortest fl telescope. This object was listed in two sources as visual magnitude 10, so I was surprised at how much I was able to get with just five 12 minute exposures.

It was great using a camera designed for AP for the first time, and it even has TEC cooling! I was able to match darks and lights temp exactly, something I have never been able to do with DSLR. And, no worries about LP or moonlight.

I've always admired the dramatic images that come out of narrowband, and I wanted to try it for myself. The first night was spent getting used to the camera and capture interface (man, have I been spoiled by BYEOS); I was able to get only 5 lights and 4 darks. More subs should smooth out the image. I struggled with a light-leaking manual filter wheel that made shooting flats problematic, to say the least.

This image used 21 darks, and 60 flats. Bias frames caused heavy vertical banding so I omitted them.

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.
