    Outside of astronomy, I'm an armchair supporter of my beloved Toronto Blue Jays in the summer, Ottawa Senators throughout the winter and the USC Trojans football(American style) team in Autumn.
    Praise be to the Gods, for the internet and the abilty of live streaming, otherwise I'd just be reading about their glorious victories(or failures!)

    A Shot in the Dark! Still redoing my TAL 2M Mount & wonder how to remove that Big upper Bearing on DEC Shaft? Not much room. Should I try a Dremel cutoff wheel?

     

    Thanks, Starman18

      Hi Starman, I sent you a pm

    Hi AndyH. I'm the amateur in US that redid a TAL2m Motor Bearing. Regarding shims for the DEC/RA axis issues, what size were the shims(IO/OD)? Did you Put a wheel/motorize the Dec axis? You posted Nov.2013. I also have a Vixen SP mount to motorize, but think the TAL could handle a heavier scope. What are your opinions?  Stay safe!  Nick

    Excellent ! One step at a time and you'll have a cracking scope. I've never really heard a bad thing about the mirrors on the Dark Star scopes of this era. I reckon most folk opted for the higher grade optics, as I've noticed, there wasn't a huge difference in price from std(1/4pv) to higher(1/8pv) back then. Keep up the good work

    This may sound daft, but after trying to visualise the size, it's actually smaller than I thought !!

    Fan-bloomin'-tastic !! Very encouraging early report. One for Skywatcher. Do you think they should hide the camera adapter under one of the foam accessory slots for shipping? Great stuff John. Have fun!!!

    But what's in the smaller box? Have fun !!

    Thought you might appreciate this Tal 100R rebuild, on a polish astro forum..... https://astropolis.pl/topic/63805-tal-100r-nowy-tubus/

    A somewhat heavy duty build !

    I think i may have used Galvoptics about 10 years ago?

    Valve springs? Heh, maybe not quite but not far away. Incredibly difficult to compress between the fingers That's a good price for aluminising. I've been out of the loop regarding that stuff. Can you or anyone else recommend places to use?? Cheers, Andy

    Note the extremely strong springs. Once collimated it stays there. Also, where the name sticker is, that's a piece of steel from a length of round bar, for balance. I can see the tooth marks where it was cut! The board is 19mm(3/4") thick. I'd guess optic focal lengths were whatever was available from their supplier at the time. As Jules says, a bit of fettling over time(no need to rush, just bit by bit) and you'll have a lovely scope. Sorry for all the underlining, my furry cat decided to walk accross the keyboard. No idea how that happened. My furry boy is an A class plonker at times.

    My mirror cell is similar but has mirror clips. It's off the scope so I'll take some pics.

    My opinion, but I like the blue hammerite colour. Quite iconic of Dark Star I reckon. My 6" is a deep copper colour. I think I prefer the blue though.
