Lacerta Solar Finder for Celestron, Skywatcher and similar telescopes

Very solid little solar finder at only 45mm overall length. No instruction supplied but it is obvious that the front black pin hole adjusts laterally and the rear ground glass screen provides the vertical adjustment to align with the telescope. The illustration shows rather large thumb screws for adjustment but the finder as received has neater hexagonal headed bolts which require a suitable Allen key but are not obtrusive like the thumb screws.
My only negative comment is that the base wedge is slightly oversize by 1-2 mm and would not fit into my SkyWatcher finder mount so required some grinding down to fit!

Advantages: Very simple but neat solid device for finding the sun when aligned with the scope otherwise not an easy task when using Badder Solar Film!

Disadvantages: Wedge base slightly too big to fit into SW finder holder - needed grinding down.

(We are checking this with the customer as we tested it on our Skywatcher Dobsonian and it did perfectly fit with a 0.5mm gap...so we have to check with him what exact finder base he's got on his telescope.../ the shop owner)
