Thanks for your encouraging words Steve

..here is the mystery..the data was on the stick ..was I mistaken? No I dont think so...although lack of sleep makes me less confident upon insisting such...as there was other stuff there and I am sure I had removed that stick to download from it earlier that day...

no doubt my back las settings are gone..I will look.
I have Bluestack (I think that's it..where you emulate the app. on your computer) And ironically I have been trying to get it to work only this week...the desk top asked for " the security key" ..I thought they must mean the Asiair password but that did not work..my desk top showed the four scopes by the way...I asked Oska (John) and he thought it may be signal and so I bought one Asiair to the van and sat it next to the computer and happily upon entering the Asiair password I got the connection.... now the only solution seems to be to drag the van close to the observatory ( where it was originally

) ...or...something else?
The security cameras ( 2) in the observatory get picked up by my WiFi and display on my tablet when in the van...so you could think there is a way to get Asiair that way..unfortunately I don't understand these things very well so the solution is not within my grasp if WiFi is available...yet..yet..I can get you tube in the observatory via my modem/ WiFi unit...so...???
Happily I fixed the roof..it only required a crow bar and a super human effort on my part to lift the crow bar above my head...it's been a good day as I got in 2.5 hours of sleep and feel ready for tonight.
Your solution to working out your filters is by removing the wheel and shining a torch and taking a photo I believe..I ask does one need to remove the wheel? As I wonder if torch light down the tube would work?..
