NGC7640 in Andromeda

This is my first completed Edge image after a couple months break. After receiving the scope back from Starizona back in July, I decided to switch to Celestron OAG and ASI174, and ended up waiting on a couple adapters from Precise Parts, reason being is not much clearance from the LiteCrawler to the filter wheel and the OAG in between.

After receiving the adapters, found out the helical focuser of Celestron OAG would not clear the Litecrawler and the filter wheel. I had to take the OAG to a local mechanics store to get a part made so I could just thread in a 1.25" variable adapter and then drop in the guide cam.

After putting all of the parts together, I wanted to test a target for guiding at 2800 and settled on this galaxy. The weather was cooperative these past few nights and guiding has improved noticeably.

Gain listed is QHY268 cam's readout mode 1 (High Gain). I should get masters built for the readout mode 3 (Extended Fullwell) soon and test.

Overall I am pleased with this setup back online and will be collecting data on clear nights.

Hope you like this result. Clear skies!

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.
