Default Three new solar transits by Discovery / ISS

Morning all,

I have just updated my site http://mysite.wanadoo-members.co.uk/...its/index.html with three new videos taken last week of ISS and Discovery crossing the sun.

In the first two the craft are docked. The third captures the shuttle two seconds behind ISS.
For transit two I was joined by Chris Batty , who also filmed the transit using exactly the same set-up...so we have a double exposure !

Finally , I have taken a cropped image of Discovery on the disk , enlarged the bitmap and applied Gaussian blur and USM.
To my surprise ( without any other manipulation ) the following appeared.
This is a negative image....




I'm not to keen on processing small images in this way , and suspect its purely co-incidence that the processed pixels produce this triangular shape.However I do wonder if Discovery was actually travelling tail first at this point in the mission ( separation plus four hours )
Time stamp is GMT

Thanks guys...

Bagged another today.............



Measured the temp by the OTA as it stood in the sunshine...36deg C...thats hot for the UK , and you can see the effects in the tube currents which make the pictures shimmer

Thanks JAICOA , there's something satisfying about hunting down an exact location then setting up and waiting for that split second .

Big problem is that thowing an LX90 in the back of the car every few days....and travelling in high temps for up to 50 miles or so to find the right spot , does nothing for the collimation of the tube.
Its now way out.....hence the often blurrrrrrrrrrrrred appearance of the images.

On this occassion , because I was using higher magnification , I managed to pull out a bit more detail .In fact most of the major components can be seen.

Thats some awesome pictures man! I always wondered how the ISS would look through a telescope and I guess I don't have to burn out my eyes with my Refractor. J/k I wouldn't be dumb enough to do that.

Quick Question - About how much does your telescope cost?

JHDD I see you are in Florida....I envy your views of the launches from the Cape !!


I use a bog standard Meade LX90 8 " scope........I guess in the US it would cost about $1500 .............. in the UK we have to pay TWICE that price for some inexplicable reason

However , any telescope with an aperture of above 4 inches will do for solar work . The most important thing is to remember to use a good quality solar filter on both tube aperture and viewfinder !
