General Optics thread...
Everytime there is a binocular/telescope/spotting scope/monocular thread there is only 10 posts before the thread dies because the thread is too specific. I like optics and would like to see a thread that lasts a bit longer. After all, a big part of going /out/ is observing and optics only make this better.

I use a Vortex Raptor 8.5x32 which i think is very good all-rounder. I use it for stargazing, watching birds and other wildlife, checking land marks, and finding routes above treeline. I'ts not too heavy although a bit bulky but for the price i don't think it was a good buy. I don't have much to compare it with because before that i used a very cheap 10x50.

Once i looked through this binocular and compared it with my vortex and the view was a bit better. I was on holidays and didn't write the brand name down thinking i would remember or find it on google but after searching for an hour i gave up. I think it was a 8X30. Anyone recognize this model or brand?
Celestron 15x70mm.
Took some recollumating, but decent for low tier.
I am looking to build a lightweight packable fixed low magnification refractor for stargazing. I have a meade etx 80 objective and a 2" 30 mm multicoated 68° Ts Optics eyepiece i wanna use. I attached a sketch of how i want to build it. It will have a maginification of 13,3 and exit pupil of 6 mm, forgiving enough to handhold, i hope. I'll have to buy guide scope rings which hold the objective and the eyepiece (i will screw out the 2" tube and just let the 3 pins clam on the hull of the eyepiece to save weight/bulk and have better balance), i'll have to buy an aluminium bar or T-bar or U-bar and drill 4 holes to screw in the guidescope rings with butterfly screws for quick assembly. Over this bar i will shove bicycle handles to hold the device. I will add a conical black fabric sleeve for better optical performance.
These are the guide scope rings i want to buy:

If i disassemble i'll only have a 400mm bar, two guide rings, a flat objective and an eyepiece without the fitting tube. i think it will all weigh around 1 kg, depending on weight of the guide scope rings...
Is this a good idea or will i have trouble aligning the thing or holding the objective and eyepiece in place with each just having one guide ring?
Feel free to comment or give improvements or alternatives

I actually meant that for the price i think it was a good buy
