Hi all.
After Peters fine effort here is my narrow field close up on the core of M8. I used this old 2x converter I lad lying about on the EOS Ra camera and 10 inch f5.6 Newtonian. FL now 2800mm at F11.2.
Shot 8 x 5 minutes at ISO 800. Hand guided with an off axis guider and ZWO guide camera.
Sharpcap got the polar alingment to within a few arc secs in minutes before starting so no dec corrections needed. Some very slight wind buffeting, the scope is fully exposed, not in an observatory.
