Not the quickest delivery and no communication when asking questions but the end result is the goods arrived so a happy ending 😁👍
Really excellent little lens, superb for widefields and it all fits together perfectly with my astro cameras. Thumbs up to Dark Clear Skies also. Simon
Excellent shop ordered the seestar s30 pro on Wednesday and received it on Saturday even though it was the Easter holiday. Would definitely shop here again.
These glassed seem rather small for an adult to wear.
Very quick delivery of high quality accredited solar glasses
