Parfocalizing your Eyepieces and Cameras to keep focus when changing them


Recommended Posts

Well, i'm sure 99% of SGL'ers know this specially in a forum with so many optical experts. Either way, i've wanted to demonstrate it on video for any beginner having difficulties to do it.

It's a simple video that show 2 easy ways to make your eyepieces and cameras parfocal. This action takes you to an upgrade on comfort during your visual observations or Astrophotography / EAA sessions because the eyepieces and cameras will be always on focus (or almost there) when you change them in your telescope focuser. In this demonstration i use parfocal rings and spacers which are inexpensive products you can buy on Amazon or any astro shop all over the world. Have a nice week-end! waytogo.gif
