IC 1805 and IC 1848

The Heart and Soul nebulae

Data acquired on 2013-09-08, at the Ashton Observatory public telescope pads in Iowa, USA. My IR filter modded Canon 550D / T2i was mounted on a tracking mount and shooting through a borrowed Canon 70-200mm f/2.8L lens. The night was warm, so to protect against undue noise in the camera I kept exposures short, at 180 seconds. Careful image calibration was done to remove as much noise as possible.

Image details:

36x180sec ISO800 sub exposures, unguided

Calibrated with dark, flat, and bias frames

Equipment:

Canon T2i 550D DSLR (Baader IR modded)

Canon 70-200mm f/2.8L USM IS lens at 200mm and f/3.5

Celestron CG-5 ASGT mount

Sidereal tracked, but unguided

Software:

Image acquisition with BackyardEOS

Calibration/alignment/integration and post-processing with PixInsight

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.
