  1. Welcome Malko! Have a look at this thread, before parting with any cash - it may well save you a fortune and some disappointment :
  2. In keeping with Valentine's day, at least in colour. Something to keep me busy while the storm rages on
  3. Managed to get out for first light with the CEM60. Initial Polar alignment and all that jazz. I was just happy to spent the time learning the software and making sure things behaved as expected. Loving the lack of backlash, after a Celestron AVX Couldn't resist a grabbing something though: 250 stacked frames, Skywatcher ED80 / asi1600mm and, as an experiment, the 7nm Sii filter Oh, and a side by side of the backlash difference
  4. I wanted to only 'ever' buy the one, so it was a bit of future proofing. Plus, the screw down terminals are to the rear rather than up front
  5. 6-8A : https://www.firstlightoptics.com/batteries-powerpacks/nevada-ps-08-6a-8a-regulated-linear-power-supply.html or the one I went for 25 - 30A : https://www.firstlightoptics.com/batteries-powerpacks/nevada-psw-30-25-30a-switch-mode-power-supply.html
  6. I dimmed one further with Neutral Density film, which is inexpensive from you favourite online auction site
  7. For power, I use 4mm banana connectors via this: https://hobbyking.com/en_us/hobbyking-powerstrip-fuse-protected-power-distribution-board.html?___store=en_us And feed that from a 12v Nevada PSU in the warm room
  8. These are pretty good and not horribly expensive, and remotely controllable: https://www.firstlightoptics.com/dew-prevention/lynx-astro-2-port-dew-controller.html
  9. I went with the 7 port USB 3, 12v powered StarTech : https://smile.amazon.co.uk/gp/product/B00SCE4E0I/ - It's aluminium bodied and well made. You might need to cover the tell-tail LEDs, depending on how annoying you find them I then replaced the mains power brick with a feed from a 12v PDU, the same as powers the rest of my kit
  10. Thank you! It didn't feel fantastic when I fitted them together, so I nipped it down with the cross head. I'll dig a couple of hex bolts out and nail it down
  11. In my defence, it was already cloudy.... Sorting the cable runs out will keep me quiet for a while
  12. Very nice! I had a crack at this a couple of seasons back, and this reminds me I need to revisit it
  13. The principle is that you keep the optical surface just above the dew point temperature, so it doesn't fog. The air volume inside the tube isn't heated, and so is close to ambient temperature, reducing air currents in the tube I'm not a reflector user, but you'll likely want to heat the secondary, the finder and maybe the eye piece
  14. I think the usual solution is dew heater bands on the appropriate optics, but the obs itself at ambient temperature Everything ends up soaked at the end of a session, so a dehumidifier (or very good ventilation) reduces the risk of mould and rust when you close up
