First light for my new scope, an Equinox 120ED, which will replace the trusty Celestron 102A for WL solar and lunar work.
I have fitted the Equinox with a MoonLite focuser which is silky smooth and much more pleasurable to use than the “agricultural” focuser on the C102A.
I read that the long light path through the Baader Herschel wedge didn’t work well with the Equinox so
I removed the click-lock holder and attached the two filters inside the wedge to a Baader T2 to C adapter. This has a built-in screw fitting for a 1.25 inch filter so I put my UV/IR cut filter in that.
Cloudy day and no major sunspots but was delighted to get focus with about an inch of drawtube showing on the focuser. Thought I would leave Barlows and mosaics for another day.
I’m not sure if the Equinox will work well for CaK – I know I will have to stop it down to about 9cm to get it to work at f10 (120/900mm scope). I have a B1200 wedge which the manufacturer only certifies to 100mm aperture- yet another reason to stop it down. Even then, there might be a lot of spherical aberration but I will try it out and see. I wont dispose of the Celestron just yet!

The visible sunspot is AR 2356
C – bipolar group, one spot with penumbra
a – asymmetric penumbra -2.5 degree or less in N-S diameter
o – very few or none tiny spots between leader or follower.
The follower here appears just as a pore
