4 pane mosaic of LDN1495 in Taurus including LBN782

This ended up being a tortuous experience which i wouldn't let go - who said taking a dark object from UK skies would be straight forwards?

Ultimately over (too) many evenings, this is a four pane mosaic of LDN1495 taken with my multi-scope-wide-field rig or I would still be taking this next year. Approx 50 hours of Lum data and 40 hours of RGB were used to tease out some details. These totalled -

L - 132x10' and 160x7' and 128x6'

R - 271x3'

G - 264x3'

B - 264x3'

This may seem excessive because it is. However i managed to not have enough data to reliably stitch the top to the bottom and had to reshoot a central strip so i guess if i had managed this first time around it would average at 15h a panel which is less excessive ;-)

I normally use Pixinsight, but i just couldn't make the mosaic processing work this time and in the end used APP for stitching the raw frames together, and then moved back to PI. This was my first time using APP and what a great programme they have produced so will look deeper into this in the future.

LDN 1495 is a large dark nebula that dominates this field of view though there are other objects including LBN782 (Cederblad 30) and a few background galaxies hiding as well.

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.
