Yes I've often wondered if contrails seed clouds.its strange high flying jets don't always leave contrails and I'm guessing that it has something to do with amount of moisture in the atmosphere.as most jets traveling long distance travel in the very bottom of the stratosphere there should be very little moisture there so I'm guessing that contrails must come from jets in the troposphere in a region just under the stratosphere.you can track them on your phone but of course you can only guess their altitude based on where they are coming from and going to in relationship to where you are.plus the phone doesn't show military or many private flights.

 

This could be my fault.
I have recently bought a Delos 17.3 , ES 28mm 68* and a ES 11mm 82*
Most likely its me, I am the reason for the clouds.
It sucks it finally cleared late last night but it was cold and I was beat.

 

My dob is apart right now but I just need on night with my AR102 to check out my new EPs.
I see its not going to be that clear up here and very cold soon.
Clear on Thur. and Fri. but way to cold. This might be the right time to work on the dob.

 

New base for it. The old one was made out of "fallaparticle board"
Have some balltic birch plywood for the new one.

 

I have the Orion XT8.
The base is coming along ok. I have the bottom all cut out.
Need to cut the sides still but my table saw was lent to my cousin last night, he is doing some work on his house.
I am really in no hurry because it is really cold at night or its just cloudy.
I will post some pics of it Donald so you can check it out when its done.

 

I think I will just keep it natural looking.
A nice coat of poly and that's it.
