Hi All,

Here's having a go.....Attached some visuals,
Alpha Cen, Peacock, Saturn-Bow, Antares.

Afocal ie camera at eyepiece, with my no-skill astrophotography therefore these are a very poor representation of what were seen in reality. One 1st order spectrum was (designed in the grating to be) much brighter than all others.

Each viewed spectrum was narrower than shown, longer and much more colour-intense. Rainbow Optics (imaging+visual version, bought in the US) 200 l/mm grating, threaded like a filter to the bottom of a 15 mm eyepiece, focussing attempted on the spectrum and not the star, 10” Bintel Dobsonian, Canon S5 IS digital but not-DSLR. Moon 35%. Rainbow Optics Cylindrical lens not attached.

I believe in exploring and discovering! So purposely did not restrict (this time) to lining up the spectrum to the pixels nor avoiding certain objects. I explored alpha Cen., Antares, A Crux, Achernar, Peacock, but leaving gamma Vel and eta Car for next time. Then I got a moon-bow. I got Saturn-bow. It’s extreme fun.

**For better-quality profiles and processing I team up with astro-photographer colleagues.

Hope you’ll share here your better images. Suggest southern objects mostly please, only because they’re less explored :-)

Regards
Sol
