Mercury Transit
From Northeast Texas I had first contact at 13:12:51 CST (19:12:51 GMT) and
second contact at 13:13:54 (19:13:54 GMT). I evidently will be unable to see 3d and 4th contacts. Should I send this data anywhere? BTW, slow, but neat. -John |

I showed it to someone while it was still in the chromosphere, and by the time I got back the comm, Mercury was already fully in the photosphere. -- Brian Tung The Astronomy Corner at http://astro.isi.edu/ Unofficial C5+ Home Page at http://astro.isi.edu/c5plus/ The PleiadAtlas Home Page at http://astro.isi.edu/pleiadatlas/ My Own Personal FAQ (SAA) at http://astro.isi.edu/reference/faq.html |

Brian, what size scope were you using? I was using a C90 Mak with a Baader
film filter. I chose that over my 10" newt because the Baader web site indicated that a smaller aperture would be better. While I was satisifed with my views, I would have liked to push the mag above 200X to view some of the sun spots in detail. The little Mak wasn't much good beyond 133X today. -John "Brian Tung" wrote in message ...

I used a full-aperture Thousand Oaks white-light filter on our NexStar
11 inch SCT at Hyde Observatory, and it worked very well. We could easily see granulation at only 87x and the disk of Mercury was quite prominent and easier to see for the kids than it was in the PST's we were using to show the H-alpha sun. Clear skies to you. -- David W.

Brian,
I am sure that you have compared the Solarmax 40 to the PST. What are the differences? Do you believe that the differences are worth the cost of the Solarmax 40?

The PST's prominence detail is just about as good as the SM 40--maybe not quite as good, but darned close. Where the PST is not as good is with disc detail. There is detail that can barely be seen with the SM 40 that cannot be seen in the PST, while the barely glimpsed detail in the PST is seen easier through the SM 40. That being said, I would not get the SM 40 as a *replacement* for the PST; the reason I would get it at all would be to "double stack" it on the PST. For a replacement, I'd upgrade to the SM 60 at the least. -- Brian Tung The Astronomy Corner at http://astro.isi.edu/ Unofficial C5+ Home Page at http://astro.isi.edu/c5plus/ The PleiadAtlas Home Page at http://astro.isi.edu/pleiadatlas/ My Own Personal FAQ (SAA) at http://astro.isi.edu/reference/faq.html |
