Hi Tony I use my lil 60mm FS60C Tak and Lunt Hershel wedge , and with my dedicated 12,5mm thats about 30x the views are awsome , I just 2x barlow to 60x if I need more power , buy daytime observing wont allow much magnification as the seeing is always really , really BAD!!! , you will have a great solar scope there BUT ! , just be careful
and check the filter for pin holes by holding it up to the sun at arms length while looking thru it at the sun and moving it around , you should not see any star like sparkles thru the filter , if so discard it as those sparkles( UV and all the bad radiation ) will be magnified in the scope to you only set of eyes .
you have , bad news
.
If it blocks the sun without light passing thru using your naked eyes at arms length , then it will be safe .
What type of material is it by the way ?
You have to be VERY CAREFUL here !! as we only have one pair of eyes .
Brian.
