It's now more than 20 years ago I bought my 4"polarex piermodel. Still love this oldie, but regretting now more than ever the lack of the astro-camera that should be fixed on top of it.... If somebody overthere isnt using his anymore and its just laying around on the attic, drop me a note. Am willing to pay a good price! I've recently found the suitable films for it (again) and a little much fed up with the dutch climate and lightpollution found me a place in the south of Italy at a relative where I can start re-using the polarex again.
Maybe this is just a "shot in the dark" but worth to try....
In the meantime its raining here as usual in Holland.(Yes, its still summer!)
