Being at a truly dark site can be disconcerting trying to find recognizeable constellations because so many more naked eye stars are visible that they can obscure familiar asterisms.

Very true.

My first Telrad died when the AA alkalines corroded in it.  Despite replacing the batteries and holder, I could never get it to light up again.  On the flip side, the original CR2025 button cell in my 18 year old Rigel QuikFinder is still going strong and hasn't corroded at all.  It's not annoying if you never need to replace it because it never dies or corrodes.

Ditto here. On my second Telrad I use rechargeable batteries, or lithium. 

What I like about aligning the Telrad are it's collimation screws, like a miniature mirror cell almost. 

For those who don't want to stick a Telrad base to their OTAs, it's not difficult to fix a base to a shoe that can then be slotted into a standard holder.
