spacers and adapters - how many is too many
i am working out how i connect my telescope up to my camera and the amount of adapters and spacers are scary. i have worked out 2 solutions to get the spacing right and all the pieces in my imaging train connected
option 1)
OTA- optec DSI 3.5 1" spacer - ditto 3" spacer - optec Gemini - AP 2.7" adapter - AP 2.7" spacer (1.5") - MMOAG 2.7" thread - MMOAG - 2" adapter - CFW - camera
option 2)
OTA- optec DSI 3.5 1" spacer - ditto 3" spacer - optec Gemini - precise parts 1.48" adapter - MMOAG - 2" adapter - CFW - camera
option 1 has a total of 10 connections and option 2 has 8. Basically the precise part replaces the following
AP 2.7" adapter - AP 2.7" spacer (1.5") - MMOAG 2.7" thread
but option 2 will end up costing me about $300 more.
Any thoughts on minimising connections in the image train to remove flexure issues? is the $300 a good investment?
