NGC 253 Stellina Test
Scope…………..Stellina: 80mm f/5 fully automated telescope
Observatory……La Cienaga Alta Observatory…Silver City, NM (a.k.a., my backyard)
Camera………... Built-in CFA
Exposures………350 x 10" = 58'
Image Width…....57 arc-minutesProcessed by Alex Woronow (2021) using PixInsight, Topaz, SWT This capture was to check my Stellina after some long-endured problems I'd been experiencing with Stellina’s failure to track accurately. The target was low over the house, with house lights in every room and from every window. The capture started during twilight and through the Silver City lights. These 10" exposures tax PI's computing and my patience—that's 360 subs for each hour of exposure! Speaking of exposures, this target probably needs another 720 subs. The next evening was cloudy, so I tried the new Vaonis app, Singularity, which on iOS can capture dark frames—I got 350 of the little devils…it helps! All in all, I not unsatisfied with this little 3” scope! Alex

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.
