The reason I joined this forum has to do with a blog I wrote for my company about plane spotters using big astronomical telescopes equipped with Powermate image amplifiers and DSLR cameras. They basically end up with a ultra-telephoto lens system of 2,000-mm to 2,4000-mm at f/10. With the wonders of modern digital ISO they can shoot at 1/1000s while pushing the scopes around the sky.


The only spotters I can find using this setup are in Poland. I couldn’t find any English language spotting forum discussing this technique. (I did find one forum where someone said astronomical scopes are not used for imaging planes). So, if you care, you can read the post here through this shortened link:

Let me know if this type of photography is "news" to the wider spotter community. It's got me interested in trying it myself!...
