This is a small collection of my images, shot at Spring 2014. There are not many images and new ones aren't coming anytime soon, since my main telescope system has toasted beyond any repair. I'm having a hard time trying to figure out, how to restore my observatory to an imaging condition with a very limited assets.

I managed to get some really rare images though. I think, that both supernova remnant images, Sharpless 221 and G65.3+5.7 SNR, are the first three band color images, showing the whole remnant, in the world! If someone is able to find other images, I'm very interested to hear about it. Both SNR images are kind of long projects. Exposure time for the G65.3+5.7 SNR 38 hours and for the Sharpless 221 was 33 hours, with the planetary nebula Sharpless 216, 58 hours. (Image at the bottom of the poster.)

Main work for the season was the large, ten panels mosaic of the constellation Cepheus. Every pane is shot three times to have a narrow band color composition. Total exposure time was 92 hours, it includes shots from six different years.

All images from the Spring season -14 are shot with the Canon EF200mm f1.8 camera lens (full open), QHY9 a cooled astronomical camera and the Baader narrowband filters, H-a, S-II and O-III.

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.
