Lunar "X" & "V" and Pineapple Rain
According to the schedule we published in the lunar discussion forum, last night showed the display of the lunar X and V.
I setup my new grab & go AR102S scope and set about doing a solar system alignment (just so I would have tracking) even though there was about a 70% cloud cover. I was just hoping to see this phenomenon through the sucker holes.
Have you ever noticed that the object you want to do your alignment on is visible all the way up until you're in the button-pushing phase. Then magically a cloud appears to obscure what it is you're trying to align on. As it turns out, any thick cloud in Hawaii can produce rain. It's a short rain shower that maybe lasts 30 seconds to 3 minutes. This is called pineapple rain. It lasts just long enough to keep the pineapples going and also just long enough to thoroughly disrupt and annoy anyone trying to use a telescope. Finally, that stubborn cloud moved and I was able to get a solar system align on the moon. I swapped out eyepieces to a 15mm (35X) brought the image to focus and there they both were (the X & V) plain as day even though it was still twilight. Through this short focal length, widefield scope the "X" was particularly bright and easily noticeable.
Next, I set about finishing an experiment with magnification and Saturn. I've never been completely confident in the magnification numbers to detect that Saturn is an oval not a disc and then detect that that oval has rings with a gap and a planet inset within those rings. So, with a 102mm scope 18x is what is needed to see that Saturn is a distinct oval, and 27X is what is needed to distinguish the ring system itself. Right after this determination was made, the clouds set in to fill the remaining 30% of the sky and so I was done.
Thanks for listening. Tune in again next week for more.
Cheers,
JT

Re: Lunar "X" & "V" and Pineapple Rain
Thank you,Terry for the share. I have enjoyed your report.
X and Y are a treat, indeed!
Pineapple Rain...
I think we have Soybean Rain here in the summer.
And Corn Clouds.
I'm glad you were able to successfully make your observation of X and Y and follow up with taking the measure of Saturn.
Cheers.

Re: Lunar "X" & "V" and Pineapple Rain
Congrats on the sighting, JT.
I seem to always get that one puff of cloud clinging to the Moon and never moving. Or the jet contrail that enjoys traveling its full length across the lunar disk.

Re: Lunar "X" & "V" and Pineapple Rain
You are very welcome Jim.
I think I may have been reading a post from Terry just prior.
I probably addressed him as JT.
My apology, TJ....I mean, JT !

Re: Lunar "X" & "V" and Pineapple Rain
JT, I thoroughly enjoyed this small scope report under mostly cloudy skies. I will do some lunar and planetary observing tonight - haven't been out with my scopes since the end of May...
Will be going to Hawaii this weekend, starting in Thursday, for my niece's wedding. Hope to do some southern sky observing while I'm there.

Thanks for the kind words. Which island will you be traveling to, if I may ask?

Just let me know if you're in need of a "fix" from an EP attached to a scope.

Re: Lunar "X" & "V" and Pineapple Rain
Hi JT. When the alignments are right, I call it the "Neon Pretzel", due to the play off light off of the lunar surfaces. Thanks for your report JT, and keep looking up.
