Edit:

First photo is First Light with new Stellarvue SVX080T-3SV telescope.

single night of data 02-26-2021

29x300sec frames = 2.4 hours integration

Final photo is total of three nights of data (02/26/2021 - 03/03/2021)

108x300sec frames = 9.0 hours integration

This is my first time imaging the Rosette Nebula.

I used the Stellarvue SFFX-1 field flattener, so no reduction. D=80mm, L=480mm, F=6.0

With all of the equipment on the new scope, it was about 18 pound setup, which is a fairly heavy payload for the CEM25p mount. Guiding wasn't great, but it seemed to manage it well enough and the image looks pretty good - I only threw away two sub-frames, and one of those was because of trees in FOV.

Initial processing in APP to extract Halpha and then again to extract Oiii.

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.
