IC1795 (Fish Head Nebula) in Hydrogen-Alpha, no stars (Derek Spratt)

IC1795 (Fish Head Nebula) in Hydrogen-Alpha, no stars

Bortle 7 urban skies but unusually cold for Vancouver, Canada (-15C). Good tracking.

This is my first narrowband project with my new ASI6200MM full frame camera attached with a TS Optics field flattener to my RC8 scope. I am pleasantly surprised to see a flat and well illuminated field right to the corners of this full frame camera on a 1624mm FL RC scope. This is a great combination with its 1.3 degree FOV and 0.5as/px resolution which matches the Dawes limit of this scope.

This is a close-up of part of IC1805 (Heart Nebula) that I completed many other imaging projects with (see https://www.astrobin.com/hoy9mz). There is a lot of foreground dust in this area of the cosmos that obscures details in parts of the image - looking at it in Ha with its high contrast B&W presentation helps see what is actually going on.

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.
