15th June 2017 HA (Barlowing) + WL (various)

[Macavity]

A much better day... The "scud clouds" held off most of the morning
to allow me to explore various "Barlowings" of the Lunt 50 and ED66.

First the default Lunt HA image:

I then did a 2x2 Matrix at 2.0x Barlowing (This awaiting processing) ...
... and decided to TRY to Barlow by 4.0x using a Antares 5x Barlow!
Not perfect, but on a quick processing was better than anticipated?



Then switched to WL with the ED66 and the CaK double stacked Filter:

Sadly I struggle to Barlow CaK images beyond 2x (Internal reflections?) 

So I switched to the rather simpler Solar Continuum for the Full Disk:



And was able to push the Altair ED66 to 5.0x with Antares (Twistlock) Barlow:





Some of the above a probably a bit optimistic (lol!), but I hope 
this will all somewhat narrow down the myriad of possibilites!
