New Lawn - How to keep it wet???
After laying down Canturf in the backyard yesterday I wanted to make sure it got a good start and was kept wet and cool so it could grow roots quickly ....
what better way to guarantee RAIN than buy some astro gear ..... so as the Postie pulled up this morning, to drop off my new Binoviewers and a Baader Cool Ceramic Herschel Prism, I could smell the rain building, the clouds rolled in and yes it is raining ........ a mixed blessing
The Baader 2" Click-Lock Cool Ceramic Herschel Prism is a work of art. This version (P) comes with the pre-installed 3.0 ND filter and Solar Continuum filter as well as an OD 0.6, 0.9 & 1.8 ND filters.
The SC filter is not really required for a top shelf apochromat so I have removed it and replaced it with the 0.9 to test the waters. (The OD 3.0 filter is and must stay in the prism for any visual use)
