A new way to look at aperture new
      #5707703 - 03/01/13 07:46 PM

So like most here I have suffered from aperturitis at times. One possible treatment is to look at our available aperture in total . . . so I grabbed the calculator and found that I have in my garage a grand total of 33 inches of aperture! Now if they just made a quinto-viewer . . .

What's your total aperture? See, it can be reassuring!

Is that square inches? If not, this is a flawed way to sum aperture. Five 2 inches do not equal one 10 inch diameter.

Sure it does. We're talking about aperture, not area. Besides, the OP is trying (I assume) to introduce a somewhat lighthearted thread to determine how many scopes/optics one has.

37 for me.

2 * 2" + 2 * 2.4" + 2 * 4" = 16.8".

They might be midgets, but at least binoculars automatically double up!

An interesting way to look at things. A rough calculation is 130 inches of aperture and somewhere around 24 scopes, some quite large, most small.

Binoculars not included.

970.85mm. Or in inches that would be 38.2" but it sounds more impressive in mm.

I thought this might be interesting so I added up the aperture of my current scopes.
WOW, was it depressing!
So, I added the aperture of the Dob I'm currently building.
Guess what? Now I'm really depressed.

Not really, I'm actually very happy with what I have. But so far I take the prize for least total aperture.

AR5 = 5"
SN8 = 8"
11TE= 4.5"
7T = 2.4"
66TE= 2"
Total = 21.9"

Modest yes , but with the awesome rural northern Arizona skies , it's unreal what an 8" scope will pull .

Oh , I forgot my 10x50s . That adds another 4" !
So I guess that kicks me up to a grand total of 25.9" .

Oops forgot the 16" GSO and the 12" Cass.

Make that 80"

Yes folks this is strictly for fun . . . just thought it might be a hoot sometime in conversation to say "16 inch Dob? That's nothing! I got 33 inches of aperture at home!"

It's a bit embarrassing. If I include unmounted optics… 127"

I'm happy right now with the job my 5" aperture is doing for me...

Again, not counting binoculars....

15" of usable aperture for me.

If you count my TMB and AR5, both cells are currently out of their tubes,then I have 25" of aperture.
