I am a hoarder so never throw away stuff that might come in useful. Being a tad environmental I try to re-purpose, re-engineer and re-use old kit that I purchased back in the day when I was gainfully employed. My old pre digital SLR lenses were first connected to my DSLR with a shiny new adaptor but then fell into disuse when I realised my EOS lenses performed better.
Now retired, with more time and reduced cashflow, I decided that rather than modding my DSLR, if I could attach my old lenses to my QHY5L-ii mono and colour cameras, I had the makings of a wide-field camera that would be more sensitive to H-alpha. BUT - old Hoya lenses have male 42mm 1mm thread connections and modern 42mm kit comes with 0.75mm threads. Try as I might none of the UK suppliers or even China appeared to have an appropriate adapter. In the end I found what I wanted - a 42mm(1mm) to T2 adapter on the RAF internet site based in Belarus. I already had the spacer and the C/CS connector I needed to complete the camera. After placing my order the adapter arrived in the post from 'Sergei' in Moscow. A very nicely engineered bit of kit! How a meerkat could make such a brilliant thing with small furry paws escapes me!
I do enjoy messing about in my shed with old bits and pieces!
I briefly tested the camera the other night in less than good conditions and it appeared to work delivering an image roughly 6 degrees square. The weather is forecast fair for tonight so I might try it out properly on the realm of galaxies in Virgo.
Ever onwards and upwards!
