True. Once you get to this size of bino, though, it's mostly for astro use. It's hard to use 100mm binoculars for much else. Could use it for birding, of course, if they're already set up and/or...

Astrophotographers like myself do have a few tricks up our sleeves.

First, the Starlink satellites are worst during dusk and dawn, but the portion of the night between the times of astronomical...

I've just got a pair of 11x70 Oberwerks. I used to have a set of tripod-mounted 25x100IF's from Oberwerk, but they were (literally) a pain in the neck once I started scanning skyward.

They were...

That's indeed the case. And many bears will do a "bluff charge" when they want to scare off a human without engaging in an actual physical altercation.

But none of that advice works with a polar...

I'll throw another "angled" onto the pile here. I wouldn't even consider a straight-through spotting scope. The birds might be on ridge-line trees while you're in a valley, or you might consider...

Astronomical eyepieces can deliver amazingly-sharp images in spotting scopes, but there's a bit of mismatch in applications between the main hardware and the user interface.

Spotting scopes...

You can't go wrong buying Televue eyepieces.

Yeah, the extreme cropping of the hawk image would pretty much render any image of it grainy.

The hummingbird image is slightly different. You'll get way, WAY more grain/noise at ISO 3200 than...

I could only dream of a D6, considering what I've got is a D5300, albeit one with a full-spectrum mod.

General rule of thumb for astro resolution is about 50X/inch or 2X/mm of aperture (look up Dawes' Limit for more on this)

The Kowa 883 has an 88mm aperture, so 176X is where you'd max out. If you...

Can't vouch for either in any spotting scope. But I own an astro-modded TE11WZ (for use with 2"-telescope focusers) and have owned a Baader Mark IV Zoom. I use/used them extensively in my 8" f/4.9...

I have the opposite issue--a Kowa eyepiece (TE11WZ) for astro-use. I only have a modded version of this eyepiece that works great for astro with 2"-eyepieces.

I can say the TE11WZ is VERY sharp...
