The Heart Nebula (IC 1805)

It has almost been 1 year since I started Astrophotography and there hasn't been a single image where I haven't learned something new. This is no exception to that.

Shooting IC1805 was a somewhat spontaneous decision. The Rosette was setting and I went out to capture one last session of it. I was delayed in getting to the dark site, and so missed most of what I could have gotten on that target. It was too early to shoot East and into Milky Way targets, as Porteau Cove is at the base of a mountain range and so is blocked up to 35 degrees in that direction, and so I settled on IC1805 in the North which has clear views.

Little did I know that Vancouver gets about 10 minutes of true astronomical darkness in July, and I wasn't really able to start taking pictures to the North until about 11:30pm, and even then the sun was still brightening the Northern sky.

This is 5 sessions, taken in 1-2 hour chunks depending on how late I wanted to stay out ( or could on weeknights ) and across 4 months this spring. Next time I'll save the North targets for the early spring as they are visible year round from Porteau Cove.

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.
