Heart Nebula IC1805 in H-alpha (Michael Mantini)

Heart Nebula IC1805 in H-alpha

The Heart Nebula (IC1805), capture in H-Alpha(3nm). This is my first attempt at trying to capture this faint and elusive nebula in the Constellation Cassiopeia. Even using my smallest refractor, at 80mm f/6, I couldn't get the whole nebula in a single frame. Using a focal reducer/flattner would have certainly helped. This shot is composed of three separate captures, and doesn't represent a lot of narrowband data by NB standards. Using my Orion ED80T on an Atlas AZ/EQ-G mount, with an Orion 50mm/Starshoot camera for guiding. Capturing camera was a Atik 460EX mono, using an Astrodon 3nm Ha filter. Did a total of 15x15min(3hrs45min) captures divided between the three combined frames. Post processing was done using Pixinsight, ImagesPlus and Photoshop CS6. Seeing and transparency were poor, as I had to deal with the moon, which was 12 days old and 83% illuminated. This reflects in the lack of significant contrast in my shot. I will try to continue to build on this data in the future, under better sky conditions.

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.
