C19 - The Cocoon Nebula

Sill imaging with my Vixen ED103S. Spent the past two nights imaging C19 (IC 5146) or The Cocoon Nebula. Was hoping to image M20, Triffid Nebula, but there is a hill on the south side of my view and it just does not get high enough to image from my Phoenix property. The Cocoon Nebula is nice too. It's getting difficult to shoot in Phoenix. The days are heading into triple digits again and last night shooting the last round of subs for this project I could not get autofocus to work in NINA. I was thinking at first it was because there was an update to the Hocus Focus plugin but then I realized I was shooting about 35 degrees up for focus and the culprit was the heat waves causing disturbances in the image. I can point up but the writing on the wall is pretty clear that the summer furnace is here and time to just image up in Overgaard for the next few months. It's typically 20 degrees cooler up there all the time from Phoenix and the evenings always cool down quite a bit all year around.

Processed this with 258 x 160" subs. I used the exposure optimization plugin in NINA with my SharpCap analysis of my ASI071MC camera. That came back with the 160" exposures to optimize SNR across the subs. I think that worked pretty good actually. Looking at getting a Berlebach Uni-28 tripod for my Vixen setup in Overgaard. I have a NYX-101 Strain Wave mount coming in about a month. That coupled with the Berlebach should make for a good stable portable setup.

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.
