Blue Horse Nebula IC 4592

This is the first image I have produced with the FSQ106 IV using the QE 0.72 reducer. I had todo some tilt adjustment of the QHY600M camera using NINA and the awesome Hocus Focus plugin. I used some Kapton tape on the side of the bayonet end of the camera to level it. the field of view is ~5.4 by 3.6 degrees @F3.6 compared to ~3.9 by 2.6 degrees at F5. there is some star distortion on the edge of the image inline with Takahashi's data sheet on the FSQ106 IV.

The weather has been just awful over the past 6 weeks and I would have liked to have gathered more integration time, however at F3.6 the photons really get into the camera somewhat quicker than at the native F5 of the FSQ106 IV and the result wasn't too bad. It's time to move onto the next target.
The data was acquired over about a month sometime only getting 30 minuets before the clouds came over. Having a permanent pier and small roll away shed makes this sort of acquisition possible for me now.

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.
