Melotte 15 - Center of the Heart in Ha (simple STF stretch)

This image is the result of first light with my "New-to-Me" AP130EDFGT scope. I swapped out the 2.7" focuser for the 3.5" and also used the Quad TCC. The scope rode on the RST-135E which handled it pretty well, though IMO, is probably a bit much for the little mount. Weight wise it is within spec and it is what I have work with at home as the MYT is now remote, so that's what we are going with!

I collected data over 2 nights with the first using the setup on the Tri-Pier and a guide scope (could't find the OAG). The second night I moved it onto my pier in the backyard observatory AND also found and used the OAG

. I really didn't notice very much of a difference between either setup image wise. We had a little better seeing the second night, but that is not saying much as the seeing here is rarely ever great. I went with 3 minute exposures as I wanted to make sure I had usable data and I wasn't sure if I could trust the mount. I will push it to 5 minutes next round as now that we have done a couple nights, I don't think it will be a problem. That all being said, I am VERY pleased with this scope (no surprise there, lol)! I look forward playing with it as the nights allow.

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.
