Going deep into the Heart nebula region reveals many faint, often overlooked, gems. I framed this image to incorporate the relative blinding brilliance and red toned warm colours of the Heart nebula and contrasted it with cool blue of the extremely faint HB3 supernova remnant in the lower right of the image. HB3 is a supernova remnant first catalogued by radio astronomers and imaged in its full extent optically in February of 2022. Also visible in the top, right of center, is a small planetary nebula(StDr 61) first discovered on 2021 by the team of Strottner-Drechsler. It is a small and extremely faint nebula 15 arcmin in size at a distance of 800LY. This project was really pushing the limits of what I can do in a bortle 6+ zone. Lots of time was needed and could benefit from even more! the Askar FRA300 held up really well do this long torture test through +20 to -20 degree temperatures.

Thanks for looking

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.
