Anyone have thoughts on using an SV Aplanat for AP? I have a DSLR and considering buying one for AP (for use on my CGEM)

Cheers,
Phil

The SV Aplanat is an Achromat so it doesn't make much sense to purchase one if Astrophotography is your goal. Used ED-80s go for around $300 and are much better choice for Astrophotography.
