  1. Congratulations with a wise decision! This will improve your experience dramatically!
  2. +1 and much more for a better mount!
  3. In your ASCOM file is an diagnostics program. If you run that it should tell you what is wrong.
  4. Couple of Moon pics with Cheap Scope

    Your Mom will be over the moon !!!
  5. The simplest way to do this, is to get focus with the unit and set that point @ 3000 . In that way you will have the full range of the MicroTouch unit used.
  6. Step Back and Take Stock

    well... two options: #1 we are (a bit) masochistic #2 we like to challenge our brains, which will drive us beyond our 'normal' capacity and find solutions because impossible is not in our vocabulary. maybe there is a third: We are totally nuts... which may very well be the case....
  7. Hi Paul, For the mount with 100% torque and and 1/2 hour slewing time per imaging session of 8 hours: ± 9 Ah Laceta 8 hours: 1,3 Ah ; Dew control @ 50% power over 8 hours: 6 Ah the total power use without the camera would be ± 17,5 Ah for an eight hour imaging session your Acer is 24 Ah and can be drained to at least 80%, so about 20Ah is available. Leaves 2,5 Ah for the Canon. This means that you could easily be out for 8 hours with a fully charged thermo insulated battery in good condition. Keep in mind that this is an estimation, hard accurate figures are impossible, for too many unknown factors are involved, like camera power consumption and slewing time as well as dew control. But a full night imaging should be possible. The proof will be in the pudding, though.
  8. I can not find any power specs for the mount except that is needs 12V, nothing about power consumption... the same for the Mgen and the dew heaters. The size and brand of the dew heaters is important information as well. If you can provide us with the amperage it will be easy arithmetic. Without that it will be a guess. So, if you can give more information, I can give you a better answer... I assume you will take spare dedicated batteries for your canon? Your choice of power source is the best available for use in the field, but expensive... If near a mains power outlet, a power adapter would be your best and cheapest option. like MarsG76 pointed out.
  9. Maybe you can borrow a FTDI based converter to try if that will work before you buy one. My experience is that the converters with a FTDI chipset always work... Prolific is a gamble, the cheap Chinese ones... well... just throw them away and buy a real one.
  10. Mighty leap in the unknown for a beginner... Do some reading before buying, please A RC telescope is one of the most challenging telescopes to collimate an EQ mount is quite a challenge to start with as well... The chances this combination will end up destroying your astro ambitions are quite big.
  11. 20 years ago money was a lot more expensive than nowadays... maybe that is forgotten? B.t.w. ... cars had similar performance 20 years ago??? come on, you don't believe that do you?
  12. I agree Louis, but the keyword here, as you said is 'expensive'... In the price range of the TAL you won't find anything to compare, so re-coating would give an above average solid Newtonian, I think. the downside of the thing is of course it's weight. It is like a canon barrel... and a bit temperature sensitive...
  13. Your name must be Lucky Luke ...
  14. Probably any machine shop will have that in stock, but machining it will be more expensive than buying those spacers, for they are probably made in China or so.
  15. On this page: https://www.astromarket.org/advanced_search_result.php?keywords=M54&search_in_description=1&page=all you will find M54 x 0,75 extension rings 5 mm and 8 mm. So you will need 2 x 8mm for 16 mm and plus 1 x 5 mm to get 21 mm extension.
