Re: Supra Status- was ([APML]_Rosette_Nebula_and_SNR_with_Schnmidt)

[Steve <sc02492@yahoo.com>]

I have used the new Royal Gold 400 and can attest to
the fact that it has essentially no red response.  I
was lucky enough to stock up on the old Royal Gold 400
"Select", which has been very good unhypered for
astrophotography use.
