I have the eyepiece and illuminator above. The 2 batteries in the illuminator are dead. Can you tell me what size batteries are required for the illuminator.
The "dead" batteries in mine do not have any identification on then at all.
I have purchased the Alan Gee MkII and need to adapt it to my 2” Moonlite focuser which is mounted to my GSO RC8. It looks like I will need items 16 and 26 to do this. Where is the best place to order these from to be shipped to the states? I have various spacer rings to use with my Altair Astro 183C PROTEC camera that had 17.5 mm flange distance. The AG was purchased from Agena AstroProducts. Thanks, Tim
I am considering the baches spectrograph to be paired with a plane wave CDK17 which is f6.8 - i see from the manual that there is significant loss of flux with this configuration - is there an extender lens that could be used to offset this effect and what might be the impact on back focus if so? thank you
