Hello fellow IceInSpacers,
I strolled into York Optical (Brisbane) at about 5 minutes to closing yesterday arvo. Went looking for a Barlow and higher powered EP (7-5mm range).
Walked out with 1 Barlow (Optex 2X fully multi-coated) sold at $87 buckaroonies AND an EP ({Tasco}York ED 7.5 fully multi coated) sold at $45 buckaroonies. A $22 discount (VIP card) on combined sale.
Took em out for a test run last night and Saturn was the target. The 7.5 has beautifull eye-relief, is nice and large/heavy, and gives crystal images.
The Barlow is light but the lense is fairly heavy and with my 10mm and 7.5mm gives a close up view of Saturn.
The Barlow does return a larger image but is blurry, dark and no finer detail except fleetingly when the image is sharp (atmospheric abberation probably).The image is a little murky and I understand the filter loss. Is this down to the aberration or possibly poor quality lense? I'm only new to the game so cant really give you technical aspects such as coma and FOV although coma does seem to be slightly evident but not enough to write home about and FOV seems redundant at this kind of Mag.
I've got 1 business week to make up my mind about said EP's. Can any one offer advice etc? "Mental" helped me out with a few choices on the forum thru the week but It was a spur of the moment decision to spend some dollars with York Optical and this "starter set" was value for money
. I guess under dark skies these materials would work better away from a city atmosphere.

Any comments are warmly welcomed,
Cheers, and over to you
