Seeing wasn't terrible this morning, so I took out the AT80EDL and TAL100RS refractors for some white light investigations with both the Lunt and Antlia 393nm wedges.

 

First up, the Lunt and the 80mm:

I then switched out the Lunt wedge for the Antlia wedge, and took this full disk and zoomed-in shot (with a 2X Barlow):

As expected, the Antlia gives an enhanced view of the faculae.

I then switched the AT80EDL for the TAL100RS, keeping the Antlia wedge:

All images were from 20-30s videos with the Canon T7 DSLR.

LYAstro - you squeeze even more out of the 3nm than I do! waytogo.gif Here's a collage from last year with just snapshots from a DSLR:

But then again, it's your product so perhaps that's not surprising! grin.gif
