Coronado SM90 type 2 ITF

Post by rcwinter »

I have been waiting an age for a replacement ITF for the above scope

Its the Beloptic version from Oliver S.

Still no sign of the filter and Oliver has no idea when they will arrive.

I noted on the chat group the some have been using substitute filters l like the Baader 35nm H Alpha as an example

I would really like to use my scope but the ITF is so poor i struggle to use it effectively

Does anyone have a spare BF30 knocking about, bought as a spare or know where i can get one easily

Hi,

Do you have a BF30 ? Just replace the ITF with an H-alpha filter Like I did, see below

Hi Mark, tried out the fix with the 45nm, worked ok, would the 7nm be better or just stick with the 45nm, of another ?

Quick note to all who have been waiting

Oliver emailed this morning to say the ITF BF30 are back in stock.

Thanks to all who commented and advised, the H-alpha filter as a replacement works well for imaging

Grab your BF30 while they are available
