First light Image of Rho Ophiuchi with the Redcat

This first light and latest image from GrandMesaObservatory.com at Purdy Mesa in Western Colorado during the month of May over 3 nights in less than average seeing conditions was taken using a new scope that we are pleased to be testing by William Optics.

The new and fast RedCat 51 APO currently being tested with the QHY128C Full Frame One Shot Color CMOS which is almost as big as the scope 😉. Our weather conditions have been very poor lately but as this is a very wide field scope it’s very forgiving and so far I’m very impressed with the results. We will be posting a mini review of the RedCat shortly.

The Rho Orphiuchi Cloud Complex is one of the most beautiful and active star forming regions in the night sky with so many types of objects such as open and globular clusters, dark, reflection and emission nebulae.

Total Integration Time 5.3 hours.

I have photographed Rho Ophiuchi quite a few times and here are a couple of my earlier images.

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.
