Aperture fever can get you into trouble. I built this one back in '92, and it is still going strong today. It's a 36" f/5, and the views are unbelieveable. Where there is a will - there is a way!!

The scope was hauled around in a trailer, and it took four guys to set it up. Today I am much lazier, and have a larger scope, but it is in a dome out in the side yard. What a great hobby.

Can you see the Moon with that little scope????

Just barely - if you keep your eye closed so you don't go blind!!!

Once we had it set up and was showing everyone the moon while waiting for it to set and dark skies to arrive. Everyone would step back from the eyepiece, say thanks for the view, and then walk off - and start running into things - because they had lost all dark adaption. We had to be careful no one got hurt…

It's as if you could climb up the ladder, slide in the tube and get shot out to safely land in a far away net!

Very nice scope!

Here's a picture of my heavily modified Orion XT12i Dob, together with the white-haired Wizard of Odd standing by its side. Few, if any, of the modifications are of the sort to stand out or be visible at all in a picture, but they sure improve the scope's performance:

1) Moonlite CR-2 focuser
2) Stellarvue 10x60 Finderscope
3) Telrad
4) Protostar spider/secondary holder with built-in heater and wiring built-into the vanes
5) Protostar quartz 2.6" secondary mirror
6) Swayze-refigured primary mirror
7) Homebuilt adjustable counterweight (magnets + iron pipe) - see structure riding atop optical tube toward the bottom.
8) Ebony Star 4552-50 laminate azimuth bearings
9) Orion primary mirror cooling fan
10) Purple shower cap, to keep spiders and dust out.

Unfortunately, the Wizard of Odd himself is not yet modified with some upgrades he could certainly benefit from.

Hi FirstSight,

That's a very cool and nicely equipped scope you got there! I like the optical finder.

Here's my 16" dob. Tube rotates and breaks in two sections. It has Palm DSC installed.

Here is a picture of my 8" Dob. Small in comparison to many but I love it just the same.

Nice scope! I'll take a smaller but better equipped scope any time... Mine is smaller than yours anyways!

Now that I look at your sign...that does not look like a Sky-Watcher...

Hi Jimmy,

You are so right, I have my signature incorrect and will change it. It is a SkyQuest, now I feel stupid, lol.

Thanks for pointing that out.

I feel positively embarrassed to post my pic after the behemoths above.

Anyway, I think mine would be at the upper end of solid tube reflectors

Drshr
It looks cool to me, good mirror size and Focal Ratio. If you are in Sydney and decide to sell it please let me know. I would like to look at and through it.

First light of another scope, 8" F/4.9 Orion. I plan on using this for video imaging, but needs some work with the Wilcox rotating rings. The scope rings didn't come with nice felt, but a thin tape, so the scope is very hard to rotate. I will add some felt pads. It is very stable on the Atlas and the Orion dual speed focuser is very nice.

Bill,

A good friend of mine uses the same scope with Wilcox rings also. The optics in his are outstanding and gives much larger scopes a real run for the money on planets. Its no slouch on wide field views either - should work great with the videocam

Pierre- Those are beautiful scopes. They make my solid tube 10" dob look like a trash can!

Brian, really hope to get use to the camera with this scope and then go to my 12" LB on your EQ platform.
