IC 1805 - The Heart Nebula

Bought a used (and refurbished) Ha-modded DSLR and got to try it out on one of the few ha-rich targets that are high enough in the horizon for me to image. I've imaged this before, but with an unmodified camera. The difference is huge. A single 240s exposure already showed the outline of the nebula.

Camera: Canon EOS 700d (T5i) - Ha Modified

Telescope: Sky-Watcher 80ED DS-Pro w/ 0.8 Focal Reducer/Flattener

Mount: Sky-Watcher EQ6-R Pro

Guidescope: Artesky 32mm Ultraguide

Guidecam: ZWO ASI 120mm Mini

Lights: 45 x 240s @ISO 1600 (over two evenings)

Darks: 15 pr session

Flats: 15 pr session

Bias: 30

Guiding Software: PHD2

Imaging Software: APT

Stacking Software: Astro Pixel Processor

Levels/Curves adjustments made in Photoshop.

First time I've also dithered my session via APT. I would have gotten more integration, but the window of darkness is limited at this time of year, and I only have one battery for my new camera. Couldn't get more than ~1.5 hours before it needed to be recharged.

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.
