On the lighter side, I finished painting my 10" f11. Based on the comments I received from my last post on first light, I paid homage to the Saturn V rocket.

Details:
10" f11
EzDSC Digital Setting Circles with my laptop
EzCBP EQ Platform
Explore Scientific 6" acromat
Explore Scientific 20mm and 14mm 100 degree eyepieces
Lots and lots of fun.
Painting everything with my 12yo and 7yo daughters...priceless.

I suggest your next project be a cannon to knock out that pole light looming over your garage. No wonder you wanted a long-focus planetary scope...

That is crazy. Expect a visit from guys in suits if your neighbors see it. They'll think your going for an altitude record. :)

Crack me up or what! +1 and props to the artists for the orange fire coming out. You definitely need to show this at Riverside this year!

Jack,

I love your finder setup: a telrad, a ~50mm, and a ~6" fractor--you might never need an eyepiece in the 10" longer than 6mm

As my friend Kevin F has said many times, if you can't have fun with it, this hobby is no good! :-)

I need to work on wobble that has been introduced with the EQ Platform. I made it oversized to help with balance and stability, but I have not had a chance to look in detail at the new wobble. I think the weight is causing some flexure in the sector hinges.

I have some other photos with my two girls painting this with me with big ol' smiles on their faces. Some of my favorite moments ever...

I wonder if the wobble is in the two pieces of single-thickness plywood of the platform. You might glue and screw some oak ribs to reduce the flexure.

That just looks AWESOME!!! It's different and unique to you. :waytogo:
BTW, one of those comments was probably mine, the one about the 1950's sci-fi movies.

If that street light in back of the garage has a photo eye you could just aim the scope at it and fire a flash gun into the eyepiece! That will shut it up for a while.

Ed D,
You are correct that your entry was the winner... :-) I painted a rocket based on your quip.

The several suggestions I've had on the tall light over the garage crack me up...I think I'll just keep the switch off, though I think the canon and flash gun ideas are worth keeping in my back pocket. ;-)

"The Document" (Dave O's marvelous masterpiece with us contributing authors) has proven to be a best seller. If I have missed anybody who has requested it, please email me again at jack.swaton@starryhost.com. I think I've sent it out to all who have requested it.

Mike, I just checked the dates of Riverside and it follows the weekend of my youngest's school campout/star party. I MIGHT ACTUALLY MAKE IT THIS YEAR to Riverside. I've never ever been and I've lived 90 minutes away from it all of my life.

Ross, I'll look at your suggestion for the wobble, but tonight it kills me to say I have to go to bed now...clear sky and no moon and I'm pooped having spent the day in Los Angeles. :-(

All,
I've passed your compliments on to the artists who did the flames, USA and Flags...my daughters beemed with pride. :-)

Jack

The altitude bearings are part of the black strip underneath the USA. They were actually cut out in the shape of Cassiopeia, however, the refractor covers one up nearly completely (you can just see part of the "W" poking out from behind the square refractor mount) and the other bearing is out of view of the camera. I used Teflon and Ebony Star. The bearings are from a 15" diameter circle (top half cut into the Cass "W").

By mounting the nearly 25lb refractor onto the alt bearing, I've balanced the scope without adding any length to the Newt OTA. :-)

where does the eyepiece go? the opposite side from the refractor?

Eyepiece? By the time you climb the ladder you are close enough that you don't even need one! :jump:

Joking of course. Yes, it is on the 'far side' .... :smirk:

The first post of this thread shows an earlier revision of this scope and gives a good sense of its scale ... http://www.cloudynig.../Number/5506210

Dave,
Now that I've stopped laughing long enough to type this post, I can respond...

CaveFrog,
Yes, the EP is opposite the refractor. A better picture is on this thread: http://www.cloudynig...5560331/page...

I'm getting quite used to the ladder now, and I think I understand the wobble in the eq platform (the flames). My south sector bearing (it is a single roller bearing, not another wide sector) is placed too far out in relation to the two north sector roller bearings. I hope to test out the theory tonight.

By the way, I have measured the weight and I somehow I mis-calculated my measurements before...the scope on top of the eq platform is 233 pounds. That includes counter balance weights, laptop, refractor, two heavy eyepieces, two power batteries (you know, the car jumper type batteries) and all my blood sweat and tears.

BTW,
In case any of you are wondering what that unit is on the left side that looks like a giant's carrying handle...it serves two functions:
1) It spreads the alt bearings apart so on that side so they don't collapse and the scope falls

2) It functions as a stop to prevent the scope from rotating past 3 degrees horizontal and tipping over. It is reinforced with bookshelf brackets.

Fantastic,

What is the guide scope?

I was able to go and see the Applo 16 take off
from FL.

Alan,
What a thrill to see that launch.

The refractor is a 6" Explore Scientific achromat. I enjoy it very much. The whole setup from wide field to high mag is really nice.

Hi Jack,

What a great setup. I would settle for just your guide scope.

Yes it was fantastic to see, a bunch from the Old Kalamazoo Astronomy Club made a trip down,

The only bad thing was my camera broke so I just have a photo of the control room.

Enjoy your Roket Ship to the Stars,

Alan O.
