Widefield scanning of nebulae


GavStar

Recommended Posts

This evening I’ve managed to coincide being in the countryside with some lovely clear skies. Sqm is not as good as it has been in the past (around 20.6) but maybe it will get darker later.

Recently I’ve been really enjoying scanning the skies just with my night vision monoculars on their own (both in London and at darker skies). But I’ve only done a couple of phone photos of these very widefield views previously. 

The winter nebulae are beginning to disappear so I’ve grabbed the chance to get series of very wide field (40 degree) phone images which give a good feel of the visual views. I’ve been surprised by how the rosette merged in the cone region and how much the California nebula extends beyond what I’ve seen in smaller fov views.

I need to do some research into some of the smaller nebulae I can see visually. The very fast f1.2 ratio of the monoculars mean that fainter nebulae are visible compared with using the NV monoculars in conjunction with a telescope (where the f ratio is quite a bit higher)

So starting from the south, going up through zenith and then down to the north....

Every time I see pics like these my mind is boggled! Just incredible to think that such intricate detail, so elusive to the unaided eye, can pop into view like that.

Barnard’s Loop has to be my favourite.

Amazing. Please, please keep sharing.

Wow, great shots! Could you give some detail on the Gear you used and settings? 

The kit is as follows:

pvs-14 with harder digital gen 3 white phosphor tube (from www.actinblack.com or www.nighttec.org)

 tnvc televue Night Vision adapter

 5nm Ha chroma filter

 Az gti Mount (only needed for taking the photos!)

After the earlier widefield session, I then set up my c11 with a 0.75x reducer and 55mm plossl to have a look at some brighter galaxies. Night vision isn’t as impressive with galaxies but I still mananged to observe my first supernova. (Supernova in NGC3254 (SN2019np))
I’ve attached a phone pic of it. In the pic you can see the galaxy south east of centre with the supernova to the right of it.

Then onto some brighter galaxies before I packed up at 2am rather cold. I really love m51 - my new favourite galaxy! The arms were great last night (sqm eventually topped out at just over 21)

The view of M65, M66 & NGC3628 really surprised me the other night on my first visit using NV. The way 3628 just stands out and catches the eye (more revealing) whereas you expect to see the more famous pair stand out more. Your shot captures how the nicer galaxy just teases at the edge of the view and seems bigger than I remember with traditional viewing.

I had my first trip down Markarians chain with NV last night and it was just as good with the 55mm plossl as I remember with the ethos21. Plenty of galaxies everywhere! Just a shame the conditions were not as good as earlier in the week.

I also managed SN2018hna in UGC7534 just before I packed up, so I was pleased with that (although somewhat cold at 0230)

Yes I agree Alan - it was the best I’ve ever seen ngc 3628. The dark lane was very obvious (something I haven’t seen visually before) and the views did begin to look like a (quite poor ?) mono astro photograph. Not bad at all ?. Views at the eyepiece are very similar indeed to these 8 second exposure phone photos (any longer exposure and the sky background becomes too bright in the images). 

I really like night vision for galaxy hunting as well but you do need aperture!!
