12.3.12

A Lynx planetary

This was a difficult object which needed some good conditions to image. I was hoping for another attempt before posting a result but it is now too far over for another try this year. It is a faint 14th magnitude planetary in Lynx. Known as Jones- Emberson 1 it wasn't discovered until 1939 and is interesting for the very blue dwarf star that is its progenitor and shows quite well on images of the subject. This central star is mag. 16.8. Details: 10" f4.3 Newt. 12 x 10 minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
