Re: First post and couples of images taken with 8" Hat in St Veran (France)
Ciao Ale, Have a look at the last slide in http://airylab.fr/contenu/HAT/fiche%20HRST%20EN.pdf, that's representative of the HaT ERF transmission curve. There is signal even below 500nm, which allows the setup to work like a Hershel helioscope in terms of flux. The good thing is that the EdgeHD are ...

Re: First post and couples of images taken with 8" Hat in St Veran (France)
Thanks for your kind comments! :-) Ale: Yes I used a 12nm OIII (Astronomik) filter.

And yes, the HaT scope has its front aspheric plate E...
