So it’s Spring and that means galaxy season. I have posted several times regarding emission nebulae with night vision but rarely regarding galaxies so I thought it’s about time! I was using my 16 inch dob with my pvs14 in prime mode and an ES coma corrector. This gives about 60x magnification. The phone pics are short exposure and imo give a good representation of the actual live views I got.

 

Galaxies shown are in order: Whirlpool, Needle, Hamburger, Hickson 44, Black Eye, Whale, Hockey Stick, 2/3 of Leo Triplet and messier 106.

Three more: pinwheel, splinter and NGC2903.

Great images!

All with Astronomik L-1 from a fairly dark site, I'd guess?

Mirrors my experiences with the new OVNI-M almost exactly. In the NGC 2903 image, you can just about guess (and after some time see) the faint arm on the right going almost to the row of stars to the South, although you see it more because the region just left of that faint arm is darker than because of the arm itself.

On M51 I think with more exposures you should be able to pull the "trident" faint tidal halo left of the companion out of the noise (I've seen it visually). You're almost there, since you can already see the upper arm on M51 fan out to the side opposite the companion. And on M106 you can already guess the fainter halo around the brighter part (again more because of the darkness between the bright part and the fainter halo).

Also cool to see the two tidal tails from the faintest member of Hickson 44. That's tricky, and almost impossible with glass eyepieces (not for lack of trying on my side, even though I could guess the orientation just once with glass eyepieces at a Bortle 2 site, and get a glimpse of those at a good Bortle 4 site with NVD).

How long were the exposure times?  Was there any stacking involved?  The lack of noise is impressive...

Well, compared to my bortle 7 pics the most noticable difference is the contrast. So I would assume those have been created under a fairly dark sky. I am also interested in the details of the capture. :)

Great images!
 

What? We're talking about visual observations, aren't we? I don't see anything new compared to glass eyepieces. I even think that you can see more through the glass. To be fair, I look more through a 24" telescope.

 

Well, yes, the picture is brighter. Dark stripes have more contrast. But there may be much fewer details. Dark skies, good vision and dark adaptation. Everything you need for viewing with glass eyepieces.

By the way, it was the contrast of the dark stripes in the NV that misled me. Need to spend some time comparing glass/NV. While maintaining dark adaptation. Start with M33.
