Hi,
ASI120MM-S is a great camera for Sun Halpha work with the PST at main focus using a simple AD translation technique in the same single movie capture !
Top PST 1S at 31.7° LAT
Below PST DS at 48.70° LAT

With the new ASI174MM I am waiting for, I should be able with the much larger FOV to use the same AD translation technique but this time using my 102/900 fluorite refractor and Coronado-SM90 ! The results should be stunning (I hope !).
