SH2-200 (40-Hr Narrowband from Silicon Valley Backyard)

This image is taken from my backyard observatory located in the white zone of Silicon Valley, California.
SH2-200 is a beautiful but faint planetary nebula and it looks a lot of exposure time to bring up the detail.
This image takes 25 hours of Ha data (3nm) and 16 hours of O3 data (also 3nm). Several hours of RGB for star colors.
Took me 10+ nights and throw away about 1/3 of the frames due to bad seeing.

Process with PI.
This is also the first time I use both NoiseXTerminator and BlurXTerminator, it works like magic.
Overall I am very happy with the result - from the standard of imaging in the white zone.

I image with my old 8300 CCD. Keep debating if I should switch to a newer CMOS-based camera, any suggestion ?

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.
