  1. https://www.google.co.uk/search?q=abandoned+observatory maybe
  2. I think there is a possible violation of the Outer Space Treaty: https://en.wikipedia.org/wiki/Outer_Space_Treaty ##### Responsibility for activities in space Article VI of the Outer Space Treaty deals with international responsibility, stating that "the activities of non-governmental entities in outer space, including the Moon and other celestial bodies, shall require authorization and continuing supervision by the appropriate State Party to the Treaty" and that States Parties shall bear international responsibility for national space activities whether carried out by governmental or non-governmental entities. As a result of discussions arising from Project West Ford in 1963, a consultation clause was included in Article IX of the Outer Space Treaty: "A State Party to the Treaty which has reason to believe that an activity or experiment planned by another State Party in outer space, including the Moon and other celestial bodies, would cause potentially harmful interference with activities in the peaceful exploration and use of outer space, including the Moon and other celestial bodies, may request consultation concerning the activity or experiment." #####
  3. Before I found Vital Parts here in the UK, I purchased caps from the US via Agena Astro: https://agenaastro.com/catalogsearch/result/?q=1.25” cap I’d try them if you’re in the US. I now see that FLO sell caps here in the UK so I’ll be buying from them in the future.
  4. This lens: http://s.aliexpress.com/J3IzQZZZ cheap but solidly built lump of metal, just got it to try some widefield with my 224MC.
  5. My memory is pretty bad these days & I cannot remember if I did get it all fitted. Move now got rid of the MoonLite & Celestron OAG and use SX OAG & SX Filter Wheel with a powered MicroFocuser. Sorry Ely I can’t help you out. Regards..,
  6. I pretty sure that CJD intends using his camera for DSO not as an ASC, as I have used my 224, so a Dark library & repeatable Darks is indeed necessary. Yes you are correct that the camera itself will give a temp readout but this is not controllable whereas using a temp probe give control. Although this temp probe is only giving the case temp & not sensor temp it bears a relationship and given using a selected exposure time is repeatable. This is how I use mine and it works. No doubt there are tweaks that can be made here and there, my current published design is a culmination of around 6 other iterations, taking the best from all of them to achieve a finished project that’ll produce results on par with the more expensive cooled versions of these or similar cameras at a vastly reduced cost. Cheers
  7. Mine gets below freezing too, everything depends on a temp drop from ambient. When used outside, as per normal use, the lower the starting temp the lower the final working temp. You would not get -15° if the ambient was 30° to start for instance. Not crowing either ?
  8. I guess you have already made sure if this but it is super important that the main mounting plate is completely insulated from coming in to contact with any of the other metal parts or the Peltier will be either trying to cool or heat this huge area.
  9. This is the TEC I use had no problems at all: HALJIA TEC1-12703 Heatsink Thermoelectric Cooler Cooling Peltier Plate Module 12V 27W https://www.amazon.co.uk/dp/B079DN16KH/ref=cm_sw_r_cp_api_.4MNBbWVZ7VKC Looking at the Farnell link, it doesn’t specify the manufacturer other than Multicomp is their own value brand & they source from anywhere. Peopke are knocking ‘Cheap’ Chinese but more than likely these days, it all comes from China. You can get a bargain by cutting out the middle man, IMO, just saying. Glad moving the box has helped ??
  10. Can’t vouch for the 30mm TEC, I specifically used a 40mm to match the alu block dimensions fully.
  11. You’ve mounted the small box on the fan side of the main mounting plate, it should be underneath as I have done. I know the sounds odd but it initially mounted it as you have only to find it restricted the drawing of cool air into the fan heatsink. Simple to test, you should notice an immediate benefit. Cheers
