20 x 120 modified elbow telescope restoration...

Posted By mike welsh

i have one of these old beasts that i'm trying to get to working order. i think it dates from the early 50's. These 'scopes were modified from the venerable M-17 elbow telescope. It was known to some older observers as an 'Apogee Scope' or perhaps 'Moonwatch Scope.'

i need to find a new (undamaged) prism for it, presently i'm taking one from my working M-17.

The two element objective lense was disturbed by a previous owner. i need to know what the proper spacing may be. The cell is tight and any added material that hangs over the edges of the lense will bind it up in the cell.

Anyone out here familiar with this 'scope? There's a pic of one on the cover of the Scott Huston book, and i'm told he used the heck out of his...

DD-1 controller woes

Posted By mike welsh

i have an older DD-1 controller that has developed major problems in the Dec motion (and a less major one in the RA.)

Specifically, when i press a Dec button, the motor will go in a seemingly random direction (either plus or minus.)E.G.: if i press the North buton, i may get a South motion, or a North, and repeated pressing of the button will bring either result in any order... (this is true for both N and S buttons.)

Also, there is a longer standing issue with the RA control, specifically the reverse function: When reverse is pressed, the motor responds normally, but when the button is released, the motor will continue retrograde (at a lower speed,) until the prograde button is tapped.

These actions seem to be independent of the slewing speed selected.

The unit is LONG out-of warrantee (and the Big O no longer does Vixen...)

Any ideas?

Anyone have a schematic?

Anyone out there know of a (perhaps) home-brewed control-box system?

So basically...

you're all just arguing over who has the best Invisible Friend?

Just wondering...

i have to ask...

Posted By mike welsh

Are people here in this forum to converse or to convert?

Seems to me that there is an awful lot of the latter, and a paucity of the former.

i just read this:

Belief like any other moving body follows the path of least resistance.
-Samuel Butler, poet (1612-1680)

Any thoughts?

(Now, let's not just see all the same hands, class!)

i can't remember if i learnt this from a minister,or school, or if somewhere it just came to me along the way, regarding Judgement:

Do god's Work.

NOT god's Job.

"Like I said, God will judge who he will judge, all men."
-Paul Titus.

"Render unto Ceasar that which is Ceasar's, but render unto god that which is god's."

i happen to think that Jesus wasn't just talking taxation here.

Do god's work, not god's job... leave the judgements to a Higher Power, if you truly believe in one.

This is a discussion forum,
not a pulpit.

If you think this applies to you, it probably does.

Thank you.

"I pray that if my words bother you or tickle your conscience that perhaps you will dig deeper into the words of Christ and find in them the meaning and affirmation you seek. "

Thank you for that.

i'll pray that you'll do the same for others' words and perhaps find in them a kernel of the truth others have found there.

Or at least some tolerance and respect for another's outlook.

i'll try to do the same.
