When I was determined to set the big LS152T, the sunspot had decided to decay away...

you consider 152 is big for solar work, while 100 is small, quite narrow minded

So my LS35T is kind of pin hole telescope

If the weather is good this weekend, let's run a workshop with the LS160 for the Macau students, we have booked a session with NPL.
