Really outstanding Wim! I know you had to fight to find openings between clouds for this one. Very few know about it or seen an image of it, and no one has seen it llke this before. Cheers Göran

Great! I would be very pleased with that first light. The Samyang is just such a great little light bucket, and like Olly I never stop it down.

Great image Olly! You captured a striking large patch of dark nebulosity just above (and partly on top of) the Soul that I think is seldom seen (at least I have not seen it as clear as this). Maybe only a RASA would reveal that😆. If you add some panels to the right you will also catch that big SNR (https://www.astrobin.com/u17lx0/C/) but then you probably need NB.

I just had a comment on my previous post that I should soon have covered all of Cygnus. Not so, much remain but I covered a part of it and just put together this mosaic. This is a two-panel Samyang 135 mosaic to which I have added about 50% RASA8 data to four of the more busy areas. There are quite a few supernova remnants in the image, some of which are rarely imaged (and unfortunately not annotated by Astrobin annotation attached). Most of the SNRs are revealed by their blue (Oiii) nebulosity, which I have here selectively stretched since they would otherwise be drowned in the Ha and starfield. You can see close ups of some of the SNRs in my recent images here and on Astrobin, where I also give some info on the objects. Totally about 40 hours at f/2, so quite deep.

Thanks Steve! I keep searching for new things, but sometimes I feel the universe is not infinite, especially when I now and then realize that I just imaged something I imaged before.

Thanks a lot Steve! Yes, there is a lot to wonder about. I would guess this one is at least as old, maybe even older as it is quite faint. It is not as "clean" as the Spaghetti, which is exceptional, so I think some of the Ha there is just old fashioned Ha nebulosity that happened to be there when it exploded.

Thanks! Ra 21h 57´, Dec 66° 28´. But it is very faint so not a great visual object, if that is what you aim for.

Thanks Wim! Maybe but then I have to get better organized so I can find them all. However, I am working on a wide field right now with Samyang 135 images as a base and RASA data on the highlights.

More SNR hunting with my RASAs. I stumbled on this one by accident when I was imaging NGC 7129 earlier this year and noticed some blue and red filaments near the edge of the image. After some digging I realized it was G107.0+9.0 which discovery was published in 2020 (https://academic.oup.com/mnras/article/498/4/5194/5904084). So now I have got around to image what may be the whole SNR. This is as far as I can tell the first "proper" image of this SNR. It is about as large as the Spaghetti nebula but it is quite faint so easily overlooked unless you image from a dark site with a light bucket like a RASA. Dual RASA8 rig with ASI2600MC and NBZ dual band (Ha+Oiii) filter. 136 x 5 min, so 11h 20´. Processed in PI and PS with the XTerminator tools. Cheers, Göran

Yes, in my experience as long as you keep the obsy laptops off the internet they do their jobs quite well. Never saw the reason why I should spend a lot of time and effort on setting up a system that would make me stay inside on clear nights when there is a great sky out there to now and then keep a look at.

No I run my three backyard obsies without wifi by taking nocturnal walks to check on them. That is the thrill of it for me and I never had the desire to do it from the sofa.

Keep them in airplane mode! I forgot that for one of my laptops recently and guess what happened.....

I continue my hunt for rarely, if ever, imaged supernova remnants (SNRs) In the second image I have made annotations of the following SNRs I could find descriptions of, all from this 2020 paper: https://academic.oup.com/mnras/article/431/1/279/1042396 Three of them also occur (with a G-annotation) in D. R. Green's catalogue of galactic SNRs (https://www.mrao.cam.ac.uk/surveys/snrs/snrs.data.html) 1) IPHASX J200002.4+305035 (G67.8+0.5) 2) IPHASX J195744.9+305306 (G67.6+0.9) 3) IPHASX J195749.2+290259 (G66.0-0.0) 4) IPHASX J195920.4+283740 (not in Green's catalogue) Finally I put a question mark on what looks like a possible planetary nebula or SNR that I cannot find in lists of PNs and SNRs. It is just below NGC 6842 (a small but bright PN). The last image is the regular annotations from Astrobin. At least it finds the Sharpless and NGC objects. RASA8 with ASI2600MC and NBZ filter. 55 x 5 min. Processed in PI and PS including the new XTerminator tools. Cheers Göran

PS. And if you pixel peep at images posted from those Sharpstar Newtoneans you may notice that they do not only give star spikes on bright stars, but that the smaller stars are squares and not round.

RASA is the way to go in my opinion (running a dual RASA8 rig now for quite a while). No dew or frost issue whatsoever even at -15°C in the middle of the Swedish winter. The camera works as a dew heater, which it would not do on a Newton. The only advantage I can think of with the Newton is the possibility to have a filter drawer/wheel for a 17.5 mm camera. Will be very interesting to hear how @fwm891 is abut to solve that - keep us RASArians posted!

Amazing image Olly! Perfect balance of detail and dust and I love seeing Nessie out there free. But now that you have freed her you may have to deal with the Scottish tourist board🤮 Göran

Yes now I can only see the dog! The only question remaining is if it will eat Nessie or just lick her. Maybe the Schottish authorities should be warned?

By the way, when the moon is gone you may want to pick up some Oiii data from this area. There are some interesting SNR remains around: https://www.astrobin.com/yzuvc3/B/

Clearly so! A dual-rig is the way to go when nights are short and rarely clear. And of course it should be on a Mesu 200😁

Yes, you have a faint scream there but I think you need a Ha filter, or one like NBZ that picks up Ha and Oiii, to make it stand out. So not a great RGB object. In fact all the images I have seen of it on Astrobin are NB images and mine is among the most "RGB like". I think a benefit with dual-band filters and OSC is that the result gives an RGB impression and can be processed just like an RGB image.

The moon is up and conspiring so last weekend I had the NBZ filters on my dual-RASA8 rig. I am still fiddling around Vulpecula and its Ha nebulae and dark dust. This is the only time of the year that Vulpecula is a bit above my horizon. The scream is often depicted in Hubble like palettes so I though it would be interesting to see what it looks like through the more RGB like data from the NBZ filter (mainly Ha and Oiii). So here it is. During 5 hours I got 120 x 5 min, so totally 10 hours before hitting the treeline (the benefit of a dual rig). RASA8 and ASI2600MC with IDAS NBZ filter on a Mesu 200. Cheers, Göran

Stunning images Adam! What scope and camera(s) did you use?

How doesn't? Thanks a lot Michael!

Thanks a lot Olly! Like with the RASA, you are usually up for a pleasant surprise when you point a Samyang 135 towards the sky😁

Thanks Alan! This is actually a Samyang 135 image and no filter, so pure RGB, since I collected the data some nights before the moon was here again and NBZ became mandatory.
