IC 348 in Perseus - 36 hours of HaLRGB from Les Granges

This is data from a week we spent with Olly Penrice at Les Granges. We had a few technical difficulties, and I did not take a careful note of every sub, hence the technical card is not complete. [One of these difficulties involved a filter-wheel failure which resulted in us shooting Lum when we thought we were getting RGB!! I suppose it meant that we did get 14 hours of Lum.]

The data come mostly from Olly's dual Takahashi FSQ 106 rig during the week 18-24 November 2017. We did get some Lum data from his TEC 140 and a QSI 683 for detail around the star cluster. Unfortunately the QSI was showing some banding issues, so I had to be careful about what could be included in the final image.

This is:

Lum: 14 hours in 15 minute exposures

RGB: 14 hours in 15 minute exposures

Ha: 8 hours in 30 minute exposures

A total of 36 hours (plus a few hours from the TEC).

IC 348 is a star-forming region around 1,000 light years distant in the constellation Perseus. The light from the cluster is scattered by clouds of dust. This reflection nebula is believed to be about 15 light years across.

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.
