The region of variable Wolf-Rayet star WR134 in Cygnus in HOO narrowband

It's been a while since I last posted something. I made use of the past couple of clear nights - well, you can hardly call night that brief darkness around midnight that we have in the North West of the UK this time of the year - to image the region of the variable Wolf-Rayet 134 star in Cygnus. WR134 is surrounded by a faint bubble nebula blown by intense radiation and fast wind from the star. The blue arc made of ionised oxygen is the front of the expanding shockwave created by the central WR134...the rest of the bubble is too faint to be imaged with my equipment...quite disappointing because I've ventured into 10 and even 15 minutes of guided exposure to get as much data as possible but the final quality is quite rubbish. Possibly I'm reaching the limits allowed by the poor sky I have from my backyard and maybe a narrower passband for the H-a and Oiii filters might help to increase the contrast.

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.
