I've used one before for camera lenses and wide field imaging. This longer one is for my 90mm triplet refractor. I find Setting 1 works well most of the time, saving a bit of power. You only need to warm things to a fraction above dewpoint to stay dew-free.
Heard great things about this lens so decided to take the leap. Build quality is exceptional, the packaging, contents etc. are fantastic. Only small issue is that dark clear skies being a vendor do not offer the choice of mirrorless camera adaptor. I’ve since brought this to both DCS & SVBony and have been assured they will take care of it which is good news.
I cant wait to give this scope a runout and see exactly what it can produce!
Christmas present for grandson, had to wait until January for the new delivery but that was fine as it arrived mid January. Very well packed and presented One small issue was resolved very quickly. Grandson is delighted with this new interest - me too!
Very pleased,
Well made kit. The tube ring should have some felt on the inside to protect the camera. ZWO's version does. I've ordered some self adhesive felt from Amazon.
