25mm cctv lens


Recommended Posts

Can anyone tell me / confirm that I need the 5mm cs adapter to fit my qhy5L-11  so this will focus at infinity with the 25mm  cctv lens  I assume I remove the c adapter and replace with the CS adapter .

Now seemed to have sorted this  thanks to Stuartjjp , orders a 5mm cs mount front end adapter , though the cheap lens i got needs another 2mm to focus so I need a washer or an O ring  .

Well it works splendidly using sharpcap pole align no problems 

and got PA down to very good , green on the traffic light system of sharpcap PA . 1.5 arc secs ish , checked later on with the mini guide scope as well once I’d swapped and that worked too , previous attempts it failed to solve I think that was due to being to far away from pole .
