Nested Supernova (Troy Cavill)

Nested Supernova

My longest integration yet with around 11hrs captured over 3 nights and my first completed image using a dualband filter features The Vela Supernova Remnant and The Gum Supernova Remnant. The light blue (OIII) mostly belongs to the Vela SNR which occured roughly 900 light years from earth while the red (Ha) belongs mostly to the Gum SNR that occured around 1500 light years from earth

Some crops of The Pencil Nebula (NGC 2736), RCW38 and some filaments that I thought looked cool

The dualband setup is a bit jank with a 2" SV220 HaO3 filter screwed into a 3d printed adapter that fits the front threads of the samyang 135 which inadvertently brings the system down to ~f3. Using a dslr there really isn't much room to fit it between the lens and the body so for now it has to work plus I suspect this bypasses the negative effect of using normal filters on fast optics

Special thanks to my gf for being a 2nd pair of eyes 💕

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.
