      Hello
      Some people may already know about this site but for those that don't (which included me half an hour ago) I can highly recommend it.
      I asked someone how they were able to identify which moon was which in their eyepiece and they pointed me to this site. You can select any time / date you wish so that you can plan your observing if you want to see a particular transit or moon's shadow.

      Just bagged 10 minutes between the clouds and got to see the Mercury shadow transit!
      Its so long since I used the Lunt that I took a few seconds to get back into the groove of tuning the double stack and letting some air into the tuner as it was flat.
      Not much else on the disc - 3 x sets of proms, 3 tiny filaments, saw one small bright flux patch briefly.
      But the Mercury shadow was nice and clear and a decent sized patch too.
      Just got back inside before it started spotting with rain! Fingers crossed for another clear patch later ...

      We are hoping to observe the transit in school (Don’t panic - we have done several transits and partial eclipses in the past so we are fine on the safety aspects - thanks). However does anyone know how I can get hold of some links to use in advance of the day that we can use to put some professional feeds up on the large screen tellies we have linked up to the computer systems these days – I am told that links on YouTube are the easiest to handle on the slightly clunky system we have to control them.
      My question comes from reminiscing with colleges that my daughter and I had stayed up to watch first contact of the last transit of Venus live from Hawaii before swapping to Mt Wilson. (We were also up before dawn on top of the local hill fort as the sun rose having lugged an old 4” reflector up there.) Of course at the time we were just browsing through the internet not taking good note of sites we were on.

      We are running a session at my local society on transits and occultations. One station will focus on exoplanet transits, and we'd like to build a very simple model to demonstrate this. We have a star (light source) and an orbiting "planet" but I need to work out how to detect the changes in light intensity and display this on a laptop, like a classical transit photometry trace below (taken from https://heasarc.gsfc.nasa.gov/docs/tess/primary-science.html).
      Is there a way to take a feed from a DSLR through the USB output to do this, else I could get an adapter for my ZWO and put an EOS lens on the front of that. I really do want a light intensity vs time trace in real time on the laptop. This model will be run in a darkened room.
      Thanks for any comments.
