Optolong LRGB SHO

Anyone who uses these filters ? Are they any good and parfocal ?

I'm about to press the button on a second mono cam + wheel + oag + filters, my existing camera uses Astronomik filters, using the Optolong filters on the second cam would save me some €€€

I am using 2” Optolong Ha Oiii and Sii filters.  I have two mono cameras and have Baader filters in the other one.  I can’t see any difference in the two.  I only shoot one NB filter per night so not sure if they are parfocal.

Thanks, but I already pressed the button, so i’ll find out once they arrive.

i hope the ASI 1600 and 120 stock is soon replenished...
