  1. Interesting, how would rotating the OTA to 12:00 position help? I also have a dew shield arriving today or tomorrow. I’ve seen suggestions to solder resistors together for heating but that is well beyond my skill level.
  2. Does anyone have experience dew heating their coma corrector? I live in a very humid area where my CC has been getting dewed over recently. What can I do?
  3. Sorry for clogging the thread but I’m just over the moon!! I’ve had the 130PDS for a few years now and I’m just finally getting to the point of being able to image without issue. I’m up to 12 hours of Ha on Flaming Star Nebula and I’ve always dreamt of getting data like this. This scope is so amazing for its size.
  4. Elephant Trunk Nebula in OSH as well as a split of SHO and Foraxx’s (thecoldestnights.com) dynamic SHO. 4.5h Sii and Oii, 4h Ha. Had an absolute blast with these.
  5. Got 4hrs of Ha data on Monkey Head recently. Boy do I love this scope.
  6. Sweet, I’ll start looking for one. Thank you very much.
  7. Sorry for all the questions but I’m dying to get this sorted out. Do you just use a generic wrap-around heater? I’ve heard that causes turbulence inside the tube while not actually heating the primary mirror. But if it works for you then I might as well give it a go.
  8. Interesting. I use a dew shield, and recently the primary dewed over and the secondary was okay. Do you cover the back end of the tube with a shower cap or similar? I think that’s what I’m missing.
  9. Curious how many people have issues with their primary mirrors dewing over? I’m going to try using a shower cap around the back end of the scope tonight, but I’m dreading the fact I might still get dewed over. Seems you have to take a DIY approach if you want to heat the mirror, and that’s intimidating to me.
  10. Awesome, I’ll give it a try. Last night I used just my dew shield. The secondary was fine all night, the primary dewed over soon as we got close to the dew point. I’ll try the black shower cap idea, this is getting so frustrating. I think if it doesn’t work I’ll have to attach a small fan to the back end of the scope. I can’t find heaters for 5” mirrors anywhere.
  11. Well, I managed to remove the mirror cell with a drill in reverse. Primary mirror is looking crisp! Here’s to hoping this solves my dew issues and I don’t need to buy heaters… although with my luck I’m expecting to have to drop a chunk of cash.
  12. Good morning, everyone. I’m currently trying to unscrew the 3 screws holding the mirror cell, so I can clean my primary mirror. However, these screws aren’t budging. Any tips?
  13. I believe so. I’lll have to get a black shower cap for the back end of the tube.
  14. Sorry for the double post but there may be hope for this dew shield after all. I took a peek down the tube at the end of the night and the secondary mirror and coma corrector both looked clear. My primary mirror, however, was super foggy and looked like it was glistening. I’ve come to the conclusion that it’s because it’s extremely dirty. I’m going to clean it for the first time ever and see if this shield ends up working. I’m still open to dew heater recommendations, though, just in case.
  15. Now taking recommendations for a secondary mirror dew heater, as well as a controller. I tried out a dew shield last night and it worked only for half the night. I’m feeling defeated.
  16. Latest image with the 130PDS + ASI 1600. About 5hrs of Ha data and 6hrs of Oiii. I have some sudden tilt I need to sort out, it bugs me a lot knowing I can have round stars in every corner. I’m also hoping to get better filters soon, these star halos are obnoxious.
  17. Oops, sorry! I took a picture of the wrong thing. I took a new one and circled 2/4 of the mini screws I’m talking about. Basically, I bought a dew shield that is *very* close to fitting. I think it might fit if that white ring weren’t in the way. I was going to just replace the dew shield with one that’s one size up, but now I’m wondering if I have to remove this anyway.
  18. Before I order the dew shield I’m looking at, I’m just wondering if I’ll need to remove this white collar looking thing? It looks like the tiny screw holding it in place are stripped or something because I can’t even tell what they are.
  19. I’m from a small city in Ontario, Canada. I live next to a Great Lake so humidity is always very high. It’s rare to be more than 2° above the dew point. I’ll definitely give it a shot, though.
  20. Sweet, thank you. I’ve read a bit about your reflections and I hope you can sort it soon. My backyard isn’t very dark but thankfully I’ve never had any issues other than my secondary getting dewed over. I’m hoping this dew shield is effective but it gets very humid where I am. Might be the best move to just get a heater + controller to be sure.
  21. Hey, what dew shield is this and how well does it work for you?
  22. Cropped view of my current project. About 5 hours of Ha data with a 1600mm-pro and ZWO narrowband filters. This newt is so dear to me.
  23. Oh shoot! I’m new to this forum so I missed your reply. Thank you so much for taking the time to do this!
  24. Can anyone tell me the size of the mirror stalk for secondary mirror?
