My observatory is going slower than I expected but then I am most unreasonable in my demands upon others and indeed myself..heck it was a one day job yet it is still going If I had another worker I would fire myself...I blame the short time I had in the public service...actually they are rather efficient at higher levels not shown to the public...anyways given I am a stand in cripple ..its going well.
As to a baffled dew tube. .. make a cardboard cylinder... .out of cardboard ...the baffles are made out of cardboard strips ..fold in half with one side having little triangles cut out...the un cut section is glued on the cylinder wall and the triangle section folds in to make a reasonable circle... paint black sprinkle saw dust on wet paint dry and paint again...the more baffles the better so if confronted with a like model you can boast the most baffles.
You need the cylinder to be larger than rhe lens and a smaller cylinder to act as go between the scope (it needs a snug fit..I use some rubber strips) and the main baffled cylinder. ..sorry to be brief but if you need more just ask.
