3.7mm Ethos Review Conclusion - Lunar Observing: Apollo 12 and 14 Landing Sites + ext

[TakMan]

Folks, I’m off to Marakkech for a few days of ‘Winter Sun’ but I managed to finish this new report before I head off...

So, attached is the latest write up from my lunar observing session from Saturday 12th Feb 2011 - and the conclusion of my 3.7mm Ethos review which may worth a look if you’re thinking of an imminent purchase of such an expensive eyepiece - even with the 20% off offer.

To those hankering after the 110 degree field and magnification that the new Ethos offers, be aware of its (unadvertised) limitations with scope focal lengths above f7.... not that I’m selling..!

Also included is my search for two more Apollo landing sites - Nos 12 and 14, encouraged after a successful attempt at finding No 15 the week before (with the help of a newly purchased; ‘Sky and Telescope’s - Mirror Image - laminated Field Map of the Moon’ thanks to Amazon).

It came highly recommended as it is clearly illustrated and annotated my renowned Czech astronomer and lunar cartographer Antonín Rükl. A £6 purchase any budding lunar observer won’t regret!

My attempts at a few quick sketches using a simple William Optics EZTouch mount are also included as well as how I got on helping a young Cub Scout start his Astronomy Proficiency Badge!

8 pages worth, so plenty to read after downloading...

Thanks for looking.

Clear skies,

Damian

Superb review and observing report.

My conclusions 0f lunar observing with the 3.7 SX pretty well match yours. I use the Baader Moon & Skyglow filter with it and it does seem to improve contrast a little bit and gets rid of any warm tint as well.
