A different view of NGC 2261 HVN

Hi everybody! Ok, this is not that "spectacular", clean nor Hi-Res type of image...

I had the chance of imaging that peculiar nebula in the past, during a star party under a very good sky using my old RC and Back-illuminated camera. The total exposure was not enough for sure but this is not the main point of the image. Recently I've planned many subjects using visual aids on the internet and I noticed, just viewing the DSS colored as visual aid, that this small peculiar nebula was indeed immersed in a very big "sea" og HII.

I've tried then to capture, even from a pollutted urban and suburban sky, such a vast glow of H-Alpha light. For doing so, I've used a very different setup in terms of light gather and resolution involving my Takahashi Epsilon and a QSI 683 ccd camera mainly in HA light trough my Astrodon 5nm. I've made long sigle exposures in bin 1x1 and bin 2x2 than I've made a composition with and without stars just for using the faint, diffuse contribution of the Hidrogen light. I then have added also some RGB and luminance data to make a final composition. I've had to use quite strong denoise here but the purpose of the image is not Hi-Res but to show a different "perspective".

Finally here it is the composite image resulting in about 1.5 hours of LRGB light and about 3 more hours just for H-Alpha data.

Thanks!

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.
