  2. The Lunar X is the near first quarter lunar illumination. The Curtiss Cross is a post last quarter lunar illumination. Different locations... Dana T
  3. 2018 Lunar X Predictions (approx "start times"): Using Werner (1.2 Sun Alt) with coordinates of: LAT -28.0 LON 3.3 Date Time Sun Angle at the X at this time 01/24/2018 0442UT -.975 @ X 02/22/2018 1807UT -1.025 @ X 03/24/2018 0657UT -1.064 @ X 04/22/2018 1913UT -1.082 @ X 05/22/2018 0702UT -1.079 @ X 06/20/2018 1837UT -1.054 @ X 07/20/2018 0614UT -1.010 @ X 08/18/2018 1809UT -0.956 @ X 09/17/2018 0632UT -0.920 @ X 10/16/2018 1930UT -0.901 @ X 11/15/2018 0859UT -0.903 @ X 12/14/2018 2246UT -0.935 @ X Average = -.0.992 @ X Someday, when I have time, I will use Sun angle at the X of -1.000 to predict the start of event. Either way, the times are very close as the start of the event which is somewhat subjectional... Dana T

  5. Approx. 25 degrees south, 1 degree east. Or, about in the middle, but only one third the way up from the bottom... :-) dt
  6. Ditto on the great images, and the 127mm mak-cass. That is still my primary scope as well. dt
  7. Thanks for posting. I love the first quarter moon... d t
  8. Yep, you should know by now that X marks the spot... Here are my predicted start times for observing the Lunar X illumination using 1.2 sun alt over crater Werner as the parameter: 2011 January 12 0012 UT February 10 1526 UT March 12 0543 UT April 10 1837 UT May 10 0610 UT June 8 1642 UT July 8 0247 UT August 6 1305 UT September 5 0012 UT October 4 1232 UT November 3 0214 UT December 2 1704 UT d t

    Lunar X

    My favorite lunar "feature"... Great job gentlemen! dana t
  12. There are a lot of "structures on the moon" on the internet, but IMO none of them are really "real" structures as they would have you believe.... d t
  13. Congrats on a very nice first moon photo. That is the same size scope that I have... dt
  14. Hello all, My favorite topic! This is my first visit here but will be back shortly. I have found that using 1.2 sun alt over crater Werner is a very nice way to predict the start of the Lunar X... dana t
