Leo Triplett - first light with Boren-Simon 10" f/2.8 PowerNewton

Revision title: Better balanced luminosity

First light of yet another rig that I built throughout the past months. The idea is to have a setup that is lightweight and mobile, provides a high resolution and is as "fast" as it could be. A RASA was not an option as I want to use a filter wheel for a maximum of automation. Therefore, I decided to combine a fast 10" Newton with a CMOS camera with small pixel size. This is a bit in contrast to usual recommendations as this combination tends to oversampling. Nevertheless I want to give it a try as seeing might sometimes be better than expected and there are also modern image processing tools like BXT, which might help as well.

Clear nights were rare and wind is an even stronger enemy for this large scope. Finally I was lucky and got a moonless night with almost no wind. I did not have to skip a single subframe, nevertheless the data is far from perfect as it turned out that there are problems with flexure and automatic focus. So I need to invest some more time to optimize the scope.

The result from just 3 hours of imaging however exceeds my expectations and I think this was the right way to go. Hope you enjoy this image of the well known Leo Triplett!

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.
