First SHO, North American Nebula

Revision title: NGC7000 SHO + RGB stars

My very first SHO image, utilizing my modded DSLR and SII filter as well as NBZ duo band filter for Ha & OIII that I've been using all along. I've got to say SII was challenging. Perhaps the DSLR isn't nearly sensitive enough to this band, even with full spectrum mod (low QE). I was only using a tracker (with RA guiding) so 480" was already pushing the limits especially with a large lens. It was still pretty faint, but with considerably more exposure time on SII vs the duo band filter it was enough to make a decent image I think. I then shot full color stars (UVIR cut filter only + photometric callibration) utilizing an aperture mask down to around f5.6 (wide open this lens has a lot of coma). Shows what can be done even with simple gear that wasn't even bought for astro (was a bird lens for me)!

Title: NGC7000 Starless SHO

Description: Added wavelet sharpening to individual channels before compositing. Did not do any noise reduction at all, except for slight in SII channel. Left a bit more luminosity in the dark regions to show a bit more detail. A bit more green in the image but overall I like the colors a bit better.

Title: HOO NGC7000

Description: I made a more traditional HOO - like image. I did use SII but added it to the red channel along with the Ha.

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.
