Heart and Soul Nebulas

I captured the Heart and friends one night from my club's dark site and two nights from my backyard. There were a couple of challenges that came up while shooting this one. First was tilt being so much more noticeable with this setup. I managed to pretty much get it sorted out by trial and error adding of metal washers under the camera holder ring to "level" the whole camera+lens rig. Also, I shot Ha in bin1 mode in order to allow me to capture finer detail. I can tell that it worked because my Sii and Oiii stars came out blocky while the Ha ones for the most part look round and smooth. However, it was harder to stretch without blowing up one part or another probably due to the reduced dynamic range. Also, my 8hr20min of bin1 Ha integration are only equivalent to 2hr5min at bin2. Compromises.

I may to back in the future and capture maybe another two nights of just Ha to complete the image but for now I'm happy with the way it's come out so far and still love the Rokinon 135 lens.

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.
