180+ year old moon

Single test 1/100s 200asa sub through 1840s Smith 3.25" scope with Olympus OM D EM 1. Sharpened and contrast in PS3.

 

I would like to say the single sub was intentional to check quality of the optics but that would be BS cos by the time I had set up under clear skies, I took 1 sub and wallop, total cloud cover. Not fit enough at the mo to sit in the cold wind and wait for the cloud to clear again so I will make do with a single. One day I will get a chance to put this scope to work properly, I seem to be jinxed with it since I restored it.

 

So a single sub is what it is so forgive the noise. It took awhile to get sharp focus as the 180 year old internal R&P is not very precise.

Pretty good for an 1840's era scope Phil. I had a bit of a butcher's at the FQ Moon with my 90mm Mak (62.5x & 89x). Neptune's close by.

More than decent though Phil for a single sub.

 

Theres nothing in the way of colour fringing is there ? At least to my eyes.

Remarkable quality really for the 1840s

That’s a really good result Phil

It's always a gamble with antique optics not just because they are hand made but because they've often had 100 plus years of neglect and/or mistreatment.

Star tests reveal accuracy in figuring etc but you can't beat sticking a camera on the end and pointing it at the moon, it may not be as scientifically based but its very satisfying to see a sharp image plus its something tangible one can show others that the objective is a good un

That looks really good Phil, especially considering the age of the optics + the age of my old eyes = nearly 250 years!!!
