I need to get my L200 up and running so as to start taking E-car spectra in time to get a regular series pre-, during- and post-periastron (coming in febuary). Hopefully something spectrographically exciting will happen as part of the periastron. The question is which lines to observe? i only have a 600lpmm grating for the L200.
I read this very interesting paper re a proposed "natural coronagraph" of dust, which the authors propose is a blob of dust which may be dissipating and may result in the homunculus nebula being invisible by circa 2030.

My CGEM mount which I bought from Logan may be coming from australia (my sister is coming to visit) this weekend. Then once that is operational, there will probably be a need to modify my dob's tube (which will be pressed into equatorial mount service until I build the 10"f5 mirror into a newtonian) to achieve sufficient back focus.
