I've got a beautiful PMX and a TEC140. Both are such superb instruments!

I've really got a bad case of the "planet photography bug" and as wonderful as the TEC140 is I need/want more aperture. I've been a refractor nut for years and have to say I'm not exactly keen to start to worry about collimation and temperature issues, but perhaps that is the price one pays to join the club. Still, if price were no object, I wonder how a TEC180 or LZOS 203/1420 would perform! I notice that my TEC, while limited in the amount of light it can collect, seems to perform close to a larger aperature SCT (how much larger I'm not sure, but certainly larger), so would a TEC180 show much proportional difference?

Anyway, I digress. A large APO is probably not money well spent even if I could find one. What would be?

Thanks,

Peter
