Input power to the controller is reverse polarity plug. Easy to open up and re-solder to correct. Should be a polarity symbol at the plug in to verify.

Why two TeleVue clamshells on that Tim? I’ve never seen that before. One should be sufficient. One handles my TV Genesis SDF just fine.

Hi, I'm wondering what SDF's acronym is?

I've been referring to my scope as "Televue 101 Renaissance Halley's Comet Edition". Just looked up SDF at TV site with no luck (ref my post above) and see it listed in chronology tables as introduced in 1984 as Renaissance 550 f/5.5.  I'll have to find the brochures I got with it, as the second owner, to see.  Unless someone who knows can chime in.

Like mine your renaissance would not have the fluorite element in the second group.

I've found the non-SDF scope to have a very filterable amount of CA, but still only needed on moon/planets. And if CA doesn't bother you, it is still very minor.

This is from the original paper work that came with a 1991 Genesis.

lol if you like a telescope to look pretty and have a shave in its reflection (in the dark a different story) get a moonraker.i think the old brass Cooke refractor look great in corner of a study full of books or maybe in the right setting sorry guys thease instruments are used in the dark anyway so pointless really to a certain degree each one to there own tho and well respected.

So added a brass TV-85, Ser. No. B-117, to my brass refractor corner. It is a pre-2005 single speed focuser model, of course, with brass pinion and wheels.

 

But like my 102 Renaissance, its draw tube is powdered black, not brass. A lack of QC must have gone on at TV when some Renaissance focusers were being assembled.

 

Looking around for ideas to replace the draw tubes with brass. Moonraker or I R Poyser may be able to make them.
