Didn't realise they needed a dedicated LP filter for that scope. Any reason?

Well if you look at the scopes design You See using a filter drawer is problematic. In my environment at home it will be a must. Will install it after spsp. BTW I am considering a a zwo asi094mc Pro

I meant the LP filter packaging mentions RASA. I thought any LP filter would do. If the filter drawer is small enough it would fit in the shadow of the secondary. I have one but still to try with the hyperstar. The central obstruction looks a bit bigger than the RASA though.

Apparently not

Might have vignetting issues with the 94, but the real estate is inviting
