West coast United States should be in perfect position.

I'm setting up now, Ive already told all my astronomy friends earlier today when I realized its a half moon night. Perfectly centered right now in the southern skies.

I took this tonight using my Galaxy S7 smart phone to my little Takahashi FC-60 mounted on my CG-4. I was using an Explorer Scientific 6.7mm 82 deg eyepiece so it was 75x. I used a cell phone adapter I bought off of Amazon to hold my phone steady.

Nice shot Ralph! 

 

I had a great view of the Lunar X in my new AP 92mm Stowaway with a 6mm Ethos for ~100x with the moon nicely framed in the eyepiece around 10 pm PDT. The lower angle viewing and the seeing didn't really support more magnification than 150x.

 

Nice to view it for the first time. I hope to explore the moon more fully with this scope in the coming days and months.

I use this converter to show me what the time is for my time zone vs UTC time. Its always confusing otherwise.

Doug,

 

I provided the original predictions based on results from a Re-worked BASIC program by George Rosenberg (ALPO), with topocentric corrections from Meeus and other formulas from Duffett-Smith.

 It was excellent here in my IM715D mak at 350X-400X!  Ditto for Jupiter and Saturn! David

Well if the Lunar X is not well placed for you,  then try this challenge,  a very small fleeting play of light I found in my image of Moon earlier this year.

 

Camera Canon T5i  using prime focus  on the  9.5 inch F/15  A. Clark Refactor .

 

Date / Time  2019/04/10 19:40:37 IMG_2168.CR2    M   1/80s ISO:200    Co-longitude  342.8 from VMA software,  340.7 WinJup

Processed four images  using AutoStakker software, then  Registak Wavelets and  Photoshop Unsharp Mask . Examining the results I thought I had a artifact from processing. I was surprised at the very next month on May 10, 2019, when I and  and other observers  viewed  the feature using the same scope and a 21 mm Plossell eyepiece.  Looked like a Rune symbol to me.

 

LROC images shows that this is the illuminated top ridge of a deformed crater.

 

Examine your older images, you may have already imaged it!

A simulation with LTVT shows the feature is in crater Polybius K.

Nice!

looks awesome John,

 

I wonder if that's observable with a 6" APO"

 

should be fun to try out, thank!!!

Thanks for warning me about Lunar X--unfortunately, clouded in.

 

Ralph, is that a Celestron branded RA drive you have on your CG4, or some other brand? Is there a lunar rate or do you just mess with it and hand adjust the DEC settings?
