Hi guys,
Thanks for the responses. I think I've figured out that a Chesire and sight tube will get me most of the way to perfect collimation. Would the Catseye 2" Telecat XL Combo Tool be the best option? That seems to combine a chesire with a sight-tube and covers my f/ratio (f/4.7 I think).
- All features of the TELETUBE XLTM and XLSTM above.
- Addition of the BLACKCAT XLTM reflective ring enabling the TELECAT XLTM and XLSTM to function both as a sight tube and as a Cheshire as well
Still looking for eyepieces. I don't mind spending a bit more on eyepieces as they seem to be things that don't get replaced too often; so something like a Televue Nagler 17mm 2"? I'll try to pick up one of those 6mm TMB Planetary eyepieces.
Still need to sort a dobson mount, just trying to form a plan from
