  1. You won't look back James. They are really great focusers. I have been running mine for over 3 years. Steve
  2. You will need a dehumidifier, I suggest you also get a Hydrostat to ensure it keeps the humidity to an acceptable level. Steve

    Hi all

    Hi, and a very warm welcome to the Lounge Steve
  5. I wouldn't advise using two motors as one would be fighting against the other which may cause issues. I would have one motor, which would be sprung loaded against the belt and two fixed idler pulleys set at 120 degrees to stop the dome from flexing. Steve
  6. Hi Ted, I purchased the pulley and belt from:- https://www.hpcgears.com/n/products/1.pulleys_belts/pulleys_belts.php You could also try:- https://www.beltingonline.com/index.php?main_page=index&cPath=213&gclid=CjwKCAjw5fzrBRASEiwAD2OSV0B9sUJZY2HMfTLUrBucMSQb7aHcK8ODQMNPoxKaluk_VZBvHZZu0hoCXBMQAvD_BwE Steve
  7. I have built three MyFocuser units for each of my three scopes and use Nema 17 stepper motors, one being a 27:1 geared unit and is directly affixed to my WO Star 1:1 focuser control side. It easily holds my filter wheel, OAG, Lodestarx2 and Atik 383 without slippage. I would never fit the geared Nema 17 to the 10:1 micro focus side of a focuser, any mishaps and the torque of the Nema 27:1 motor would seriously damage the fine gearing of the micro focuser. My other two focusers are driven via toothed belts. Steve
  8. Hi Barnes, and a very warm welcome to the lounge Steve
  9. Hoping to add some more Ha detail to this:- Hopefully when monsieur Blobby backs off I'll try to add some RGB Steve

    Hi David, and a very warm welcome to the Lounge Steve
  11. Hi Hugh, Thanks for the update. I've now received all the components to build the project. Hopefully should start building Friday. Kind regards Steve
  12. Totally agree with all comments regarding full dome installation. With exceptions of:- Use Cat6 cable for future proofing, even optic cable if you can install it. Minimum three ducts with two spare "pulla wires" in each duct, in case you need to add any additional cables. Steve
  13. Hi MrL, and a very warm welcome to the Lounge Steve
  14. Any chance of Charon next time? Seriously, Pluto is extremely difficult presently as you have stated. Think of the long lonely nights Clyde Tombaugh endured whilst gathering evidence of the existence of Pluto. Steve

  17. The problem with autofocus is that you have to be reasonably focused in the first place to get it to work effectively. Steve
  18. Absolutely, I did similar, any old rubble I had lying around went into "the pit" Steve
  19. Thats a damn fine hole & I like the Feng Shui layout of the blocks as well Steve
  20. I use a Baader Variable Locking T2 Extension in my imaging train. The tilt stems from the CCD sensor. Steve
  21. Either that or just tracking the stars in real time, close to the zenith.
  22. Gina, why don't you sort out your meridian flip during the day. You will not lose any imaging time. Steve
  23. Rather nice images Gus and to say they are affected by atmosphere, as they are low in the sky, makes them even more appealing. Steve
  24. Absolutely despise getting back spacing correct for that ultimate flat field. I have an AA80 triplet and added a rather expensive focal reducer to the imaging train. Not only did I need to adjust the back spacing but I had a slight tilt as well. After adjusting, tweaking, refocusing, checking the image ang going through the same tedious routine, whilst being tired, cold and in a cramped condition, is not a pleasant experience. If the devil had appeared, whilst I was agonising over my scope and offered to miraculously sort the issue, my soul would have been forever his. Steve
  25. Lovely NB image and nicely processed Steve
