Another fine report, Martin. I see clouds in your skies ... again. I'm dealing with an incoming hurricane/tropical storm here. I will need to dismantle all my rigs before the high winds and heavy rain arrive by Thursday
Mr. Frosth (Sir), I love your idea of using brush molding - that's innovative. Please, always with respect - where I reside, the winds can be, well extreme, along with my buddies the wasps, hornets, yellow jackets, moths, and flies - and as you have pointed out air blown dust and dirt - all make these small openings - well a challenge. I have built 2 roll-off roof observatories - always had problems with closing things from the outside and (again) as you make clear - water finds its way into anything and everything. I have built (coincidentally) 2 domed observatories and I am in the throws of building a new dome this spring. (I got the pad/foundation poured, but it's just a little cold to be working outside now. (I'm old and soft I guess.) No matter what design one uses, closing things from the outside elements is a challenge. If I were Elon or Bezos, with unlimited funds I'd go the Observa-dome or Ash dome way - you know, buy a structure from the people who make domes for those with unlimited funds, but alas, I am not Elon or Bezos, so I will be using the router and jig saw to start cutting dome arcs - for the new project. Here where I reside, yes winds are always a consideration, but so are vandals. (I will share a small story with you.) I have an acquaintance who had a .6m or 24" professional telescope which cost him (for the mount and OTA) around $50k, it may have been more costly - it was in a block structure with a metal dome - but a few miles from his residence. Locals broke into his observatory, and stole his equipment - (he) never recovered anything, and due to his lack of being proactive, he had no insurance. Catastrophe! In any case, life goes on. Thanks for the great videos: I am learning from you and will apply some of the techniques that you are using, on my new build. Take care my friend and thank you.
Great video, I like your brush and rubber seals idea, it should work well. Thanks for the tip, I’ll have a look on Amazon as I will be needing some of these!👍 Clear skis!
Thank you! Yes, seems to work well. I haven't had any water inside even though we've had heavy rain non stop for days. I've also noticed that I can run my heater fan on a low setting for 30 minutes after the observatory has been open to reduce the humidity in it with 20% in comparison with outside.
Excellent solution with the brush strips. I'm going to look for them on Amazon. Possibly it works better and with greater durability if you fix the brush to the roof. As the brush is placed, it will deteriorate rapidly. Hugs 😊
Love what you've done with the brush molding! Do you happen to have a link to the one you purchased? I cannot find anything on Amazon that is as wide as what you have. Curious as to how well it is working.
Ciao, innanzitutto bellissimi i video e bellissimo osservatorio, potrei suggerire di usare gomma liquida bostik o altra marca per impermeabilizzare le rotaie dove scorre il tetto e tutto sarà anti acqua e sigillato.
