M35 and everything (LRGB)

Revision title: LRGB

I added this to the Astro bloopers group because I completely failed to capture the RGB data for this beautiful cluster. I set out with my Meade DSI III pro to capture a LRGB image only to find that the old RGB filters that I have do not fit my filter drawer and have the wrong thread size (clearly something that Meade used in the past)… not very exciting in monochrome

M35 (NGC 2168) is 2,158 LY away in Gemini, the ‘companion’ cluster NGC 2158 is about 11,000 LY away - they are re thought to be about 2 billion years old. A colour image would show the beautiful golden stars of this older cluster!

A second hand Baader RGB CCD filter set is on the way 😊 They’ve arrived! The final version an LRGB composite as per Rev. All good apart from the blue filter which has been rehoused in a larger (older) Baader cell, which does not fit my Altair filter slide. Grrrr.

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.
