I run Simrads on my night guns. This is a clip on unit that uses day scope. I run a PVS14 head mounted with night cap for walking in and scanning. I run a T20 on my rifle for IR light and one hand held for scanning. I use badger rings or Sphur mounts with simrad caps for clipping simrad on. The simrads are a little bulky, but well worth their weight IMO when it comes to clarity. The other thing I love about the simrad is that centerline of objective sits higher than center line of scope objective. What this means is I zero the scope at night at 100yds using one of their targets. On my 253, it sits 3.5" higher than day scope. To zero the scope you make sure your day scope has a good zero, then clip on the simrad. You want to be shooting 3.5" lower than day zero at night, then I dial the scope up to be zeroed at night. Now both are zeroed, and I actually hold zero out to I believe 340yds at night with my 22-250. I dial it to .9 Mil and run it. No hold overs, no worrying about anything most times. Point shoot, done.
I have used two different tripod set ups as well.
First is a bog pod with a hog saddle. Very effective, light weight, and extremely easy to use at night.
Second tripod setup is a manfrotto with magnesium ball head and QD mount for hunt. WAY WAY more sturdy than my bog pod, but it took me a minute to get quick at setting up in the dark. Only had it 2 months or so, but love it so far. That set up is the second one in this pic.
I am sure I am missing other details, but this is cliff notes version. I am in now way Night vision smart, but have spent some time behind these 2 set ups. Any other questions, ask away. ill see id I can give a dumb answer. That's about all I am good for.
