IC1795 - Fish Head Nebula

Finally got in my new SVX 102T and decided to shoot the fish head nebula. I've been ignoring this object, being more captivated by the heart nebula nearby, but after shooting a few subs it really grew on me. Compared to the RASA it obviously takes longer to acquire data, but it was much easier to process -- though I may have pushed the data a little harder than I should have. It will take a little bit to get used to, but overall I'm happy.

AstroPixelProcessor

---------------------------

Stacked with default settings except LNC set to 2nd degree with 3 iterations to help with deviating gradients.

Pixinsight

--------------

1. Deconvolution on Ha only. Removed stars with starnet++ during deconvolution, and then placed back.

2. TGV Denoise & MMT (Jon Rista method) used for noise reduction.

3. STF Stretch applied.

4. PixelMath SHO combine.

5. Color adjustments, SCNR, masks with curves, etc...

7. Slight star reduction on combined image.

Photoshop

---------------

1. Saturation increase, final color tweaking.

2. Spot cleanup of over-saturated stars.

3. Smart Sharpening.

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.
