I know some people here like telescopes and should be waiting to take videos or observe the transit of Venus across the sun on June 5. What it may do to the atmosphere ionization and radio propagation I don't know, maybe nothing, but it's worth looking at.

Are FETs supposed to glow like that?

Yup,
I WAS excited... but now looks like it'll be cloudy here.  Cry

I even have a new Hydrogen Alpha filter set for th escope and everything.

Don't guess I'll see it the next time either..

Partly cloudy here, so probably no looking. I'd use the ol' pinhole and cardboard trick.

Pinhole works good. So does a #15 welding filter. For the exlipse, I used my #9 gold welding hood over my polarized RayBans. It was very comfortable viewing.

For exact viewing times, and a map of the expected path over the sun's disc, use this calculator.  Enter your city, state/province and country, and click on "Locate".  Times will be given in GMT− (x hours), corresponding to your time zone.

Pay attention to the time as indicated in GMT − x and calculate appropriately, since in some areas near time zone boundaries, the clock may not correctly indicate your time zone.  Also, the clocks are programmed to show the actual time of day in standard time, not DST.

For example, the times shown for this QTH here, indicate it starting at 4:04 PM, GMT − 6, which is Central Standard Time. That would be 5:04 Daylight Shifting Time.

I recorded the entire 1st transit which occured in the morning. I had the whole transit recorded on my laptop and the video and photos were excellent. Some SOB stole my laptop the next day out of my car and that was that.

This one is later in the day and I'm not sure I will set up the scope and try again. The sun will be low and it's supposed to be cloudy.

I took this one (of several others) on the last transition.  Taken with a Nikon 5700 and some neutral density filters.  Sadly, I will miss this one due to cloudy conditions.

Transit underway here in Michigan.  I thought I'd try to get a picture or two of it...

Currently running a big homebrew transmitter (pair of 250THs modulated by a pair of 810s) paired up with a National HRO-50.  I also run a BC-610-I / NC-2-40D combo which is a lot of fun too.

Nice!

Went back to the oirgs  and saw the sunrise pics I took while getting ready.  Horizon is slightly tilted.  Never did any corrections

A couple of hours into the transit now.  A couple of more pictures to share... Using the projection method. A cheap telescope and a piece of white paper... works pretty good!

Shot a few with my SLR and a telescope solar filter with a home made adapter (out of packing tape and electrical tape at the last minute). Here is one.



A few sunspots in the center.

Pat,
I use a T2i as well for astrophotos....

Unfortunately, it was cloudy and rainy here...


Nice pic.

Jealous of those with clear skies.

I was too lazy to get a scope out. I had a Thousand Oaks filter for my 80 MM refractor and I made an adapter with tape to put it on a Canon 250MM zoom and hand held. Set the lens to F11 and the shutter at about 1/1200 and got some decent hand held shots. Better than I expected. I did use a monopod on a few to steady.

I was using a T2i  also.

It was cloudy all day and the sun popped out about 4:30 this afternoon and by 6:00 is was clear.

I wish I had some more time for astrophotography...... and radio... and offshore fishing......and .....................

Nice pics, guys.

We expected to be cloudy here (Stephenville, TX-- 65 WSW of Fort Worth) so hadn't really planned a viewing. At 1500 it was clear and we went for it. Took out 3 scopes and 2 SunSpotters. The SunSpotters are small projection viewers. We were out from about 1600, an hour before exterior ingress, until about 1830. Had various filters on the scopes, including H-alpha, so we got good views of the sunspots as well. With just one email to the faculty, staff and students of the university, we ended up with about 90 folks dropping by to look and even got two bookings for planetarium shows. Not bad for such a quick event. Had I known the WX would be good, I'd have put it on local BC radio and in the paper and had a real crowd.

Sounds like a nice gathering.
I'd set up my Quantum OTI 6" Mak. earlier on equitorial mount but then the clouds rolled in. - and in. - and in and stayed.  Well, like others I did get the sunrise eclipse last time.

Also had the 3.9" scope in car with alt. az mount and thousand oaks filter for quick trip to a cloudless location locally, but didn't happen.  Clouds were solid overcast for entire region, no hint of a peak through.

I was particularly looking for Venus' atmospheric ring on ingress this time. Didn't see such on egress in 2004.

Also had camera set on lower pixel resolution last time to conserve memory for regular type shots earlier. Ah well, always something to trip us up - Grin
These days, camera memory and resolution not even a remote problem.

The 2012 event was the reverse and sorry I got clouded out.
