NGC7000 NB Wide Field (2nd Light with Samyang Rig)

Revision title: Reworked with BlurXterminator v4

I recently posted the 1st Light image of NGC7000 with my new Samyang 135 rig. While I was pleased with the overall rig. The image was less than spectacular. As one should never evaluated a rig on the 1st light image, but inspect the image and see what can be done to improve the results. I had star issues BAD with the first light image. focus was good. Integration with SGP was great.

Things that I changed after the first evening with the rig. I loosened the belt tension between the lens and the ZWO EAF. Way too tight and that helped tremendously. I also imaged at F2 on the 1st Light Image. I moved the F Stop on this image to F4. The next night out will be imaged at 2.8. I am hopeful that the results will be as good as this image. I also shortened the exposure time to 60 sec for each sub. Left the 533mmPro and used the same filters. All subs were captured at 200 gain 50 offset at -10C. I know it is not an apple to apple comparison. However, I am looking for the correct configuration and best practices for this rig. Also I wanted to capture all three channels in one evening with enough subs in each channel for a good 2x drizzle. The pixel size of the imaging camera is not a great match for such a short FL, however, a good 2x drizzle will help tremendously.

I will include an Aberration Inspection image from this image as a revision. I did have several people express interest in getting a similar rig. I hope the continuing improvement of this rig will help folks decide to join to Samyang 135 club...

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.
