Eta Carinae Nebula NGC 3372 in Carina (aka The Keyhole Nebula)

Eta Carinae Nebula (NGC 3372) in narrowband (SHO pallet). This image consists of: Ha 25 x 180s , Oiii 28x 180s, and Sii 37x180s, guided subs. Camera is the ASI1600MM-C, for this image gain was set to 75 and Offset to 20, sensor temperature was -18C. Eta Carinae is a very bright object and it is easy to over expose, so even though this is narrowbnd I dialed the sub lengths back to 180s. Telescope is the TS80 running the reducer corrector to take it to f5.5. The object size and field coverage of the TS80 at this focal length seem to be a good match as far as getting everything in frame. Mount is the CGX.

Processing was in DSS and Photoshop CC, with colour saturation dialed back. A luminance layer was included using the Ha layer, to improve contrast.

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.
