The VersaPlate on my MX+ is flipped 90° [perpendicular] to the normal, single scope orientation; this allows it to carry multiple scopes. The 132 sits on the west side with a RedCat guider setup piggyback, while the Borg 107 sits on the east side with the Borg 55 piggyback. With this setup I have three different FOVs available. Sometimes the primary targeting scope presents an interesting FOV for another scope. I was gathering OIII and SII data with the Borg 107 and fired up the William Optics 132 FLT, having finally improved the back focus distance. I decided to see what the 132 FOV had to offer; this was it.

As things are mounted at present, I have not employed an aimer...I have the JTD for the 132 and an ADM for smaller scopes...on either side because it would raise things pretty high. This can become problematic when the mount is heeled over and I am trying to keep the guider on one side and the 107 or 55 on the other side both in the shutter opening of the Dome. Thus the 132 and the 107 do not both place a target star in the FOV center. So this image is just where the 132 landed when the 107 was on target. But I decided it was interesting, and I grabbed some data. Kinda fun...

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.
