  1. Thanks guys, a couple of wraps of Plumbers PTFE take around the thread of the helical under the green wheel, has done the trick..👍🏻
  2. One thing I will say is no amount of tweaking any settings will make a difference if the firmware is the old version, either in the driver or in PHD, trust me I tried everything….
  3. Hello, I recently bought a second hand SW Evoguide 50ED, and it’s in mint condition and was happy with it, but I noticed that with the helical focuser when I change direction from in to out or vice versa, there is backlash, in fact the green focusing ring will focus one way, and as soon as I swap direction the same ring will move approx 1/4 of a turn before it starts moving focus the opposite way. Yo can actually feel the backlash as it goes really loose for a 1/4 turn before it picks up and starts to move.. So my question to any owners of this little scope, is this normal or do I have an issue and can it be taken apart and looked at..?
  4. I had this exact same issue, and contacted Terry at SX, who said it was in need of a firmware and software update in the camera, so it went back to him to be done, and when it came back all was good, I think he can send you the files needed and you can do it yourself if you wish too, but I just sent it to him as I did not want to take the risk…but it is normal if the camera had old firmware in it…👍🏻
  5. Yes, it’s a non smell type, as I did know about the issues with the stuff that smells of vinegar when curing… The dome steamed up as soon as I sealed it down, and is slowly now clearing, and the desiccant is changing colour already slowly too, so hopefully it’s working…👍🏻
  6. Does desiccant work best in cold or warm environment to remove moisture from the air…? Wonder if it will be better indoors for a week rather than the gargae to remove any moisture…
  7. Ok, so my solution is, and thanks for all the help on this thread… I have sealed the dome area completely from the box itself. Silicon sealant around the base of the lens holder as that where the gap was. So a much smaller volume of air to contend with. And also put a pot of desiccant in the dome and will now leave in the garage for a week or so for the desiccant to do its thing inside the dome, then I will fit back outside…I sealed it in the garage where it was colder. So fingers crossed this works…
  8. That’s a great single sub, well done and looks like a great set up..👍🏻 but for us pixel peepers there is nothing to peep as the image is much to compressed….
  9. Sounds like you have the exact same issue as me…
  10. Those case screw holes go all the way through to the bottom and have a hole all the way through, they are as.o outside of the internal size of the box and outside of the seal around the lid, so no chance at all of any water ingress from there…and there is also a seal between the dome lip and case, and in sealant in those screw holes too..
  11. Does it not make sense that if the air in the dome is warm then when it hits the inside of the cold dome it will condense, but if the air in the dome is cool pretty much as cool as the dome, then no condensation will occur…🤔? I ask this because I can seal the dome chamber completely so it’s not linked with the air in the box itself, as this may help, and not heat this air in the dome…or I could leave the heater ring in the dome on, which would be best, heat in there or no heat..? also I could put a couple of desiccant packs in the dome too…thoughts…?
  12. The laws of physics also say that to prevent condensation you need heat and ventilation, so a sealed unit may not be the answer..As it is far worse now than it was before it was totally sealed…
  13. Orange, and it turns green when wet…it was brand new several hours ago when I put it in, use it on other things and works really well, so I know it works fine…
  14. Well I give up then, as the desiccant was new and unopened and perfectly orange and not green as it is when saturated… I have 200g in there, and the box is sealed…and it’s far worse now with the box sealed, than it was before I sealed it and had it was vented, as then it only dewed up when it rained, now its like it all the time… I am totally out of options..🤷🏼‍♂️🤷🏼‍♂️
  15. And here is what the unit looks like, the lid screws are outside of the lid seal.
  16. The vents are truly sealed now trust me, I have sealed inside and out of them, the box is a water tight version with a rubber gasket seal on, and the dome is sealed to the box too, the cable inlet is also totally sealed, and there are 8 desiccant packs in there, the RPI produces a lot of heat, and there is a heater ring also in the dome area around the camera, and still this is the image from the camera and it’s not raining….☹️ The dome is soaked on the inside…
  17. Hmmmm, when you seal it there is air sealed inside, this air will have moisture in it, and as soon as the power is on, the air warms up, then hits the dome on the inside which is cold as it has cold rain falling on it, so the warm air condenses on the inside of the dome, then drips down, re evaporates and condenses again, in a cycle… why do the holes need to be underneath and not on the lower sides..?? As long as they dont let water in…?
  18. Ok, so sealed the unit again and as soon as I put it back outside the dome is misting up from the heat inside, so having it sealed is not the answer… I have read loads of posts about this and the consensus seems to be to have heat and ventilation, which also does not seem to work, so I am at a total loss…☹️
  19. Yea, have tried, it was fully 100% sealed when I first built it, with desiccant and still was the same when it rained… The rain will always cool the dome, so if there is warm air inside it will always condense….right..? no idea how other people deal with this issue…🤷🏼‍♂️🤷🏼‍♂️
  20. Well it was sealed with RPI and dew heater filling the unit and dome with heat, and was fine until it rains, which causes the dome to cool and condensation to form, from all the warm air inside, how can this be stopped during rain..? it was because if this I added the fan and extra hole on opposite side, which have grills on the outside to stop rain entering and a foam on the inside to stop bugs and such like. It actually seems a bit better with less heat inside. ie, when I disconnected the dew heater ring..🤔🤔
  21. So a few months ago I built an AllSky camera with an RPI4 and the RPI HQ camera and all worked very well, it’s in a 125mm square sealed project box, with a dew heater ring around the lens in the dome area, but having real issues with condensation inside the dome, now I have read a few threads on here and other places about this issue and have followed some advice, bit to no avail, in fact it’s worse.. I should add that this is mainly after rain that the issue occurs, it seems fine at other times… I have added a 40mm fan on one side pulling air out of the unit, and a 40mm hole on the opposite side for air to be drawn in, to try and ventilate the unit, the RPI4 does generate quite a bit of heat, and have tried with the dome heater ring on and off, and seems better with it off, but can’t lower the heat any more as this comes from the RPI The dome area is open to re rest of the unit and not sealed off at all.. The air is obviously warm and condensing on the inside of the dome, but many others use this same set up without issue…so not sure what to try next.. Any ideas…
  22. As you have updated NINA and ASCOM, you will have to re select your camera from the drop down list in NINA, also best to install the QHY all in one native driver and use that in NINA, it’s better than the ASCOM version..
  23. He used to be a regular here, @RayD he has not been on here since 2021, maybe not in the hobby anymore…🤷🏼‍♂️
