Jupiter is occulted during daytime by the moon on November 9, east coast, roughly from 11 am -12 noon. So today I have been practicing observing Jupiter in daytime, having set up my G11 last night. I put a 5 inch f/6 apo and a 5 inch f/10 Mak Cass on it and found the gas giant at 0500. Tracking Jupiter with the G11 allowed me to observe until 1 pm today, when the planet was lost in the trees to my west.
Thinking this through, potential problems are losing Jupiter during the meridian realignment (I went for the moon instead during this process and it worked fine), having a solar burn due to a mount failure (keep the cap on when not observing) and of course clouds (pray).
The sky being so bright, anything to reduce stray light will help see the planet. With this in mind, what telescope would make the most sense here? In my practice session today, the refractor did better than the mak-cass. Jupiter showed a very very dim image today, with little surface brightness--Venus was quite the fireball, however.
I'm thinking that a slow refractor with a big aperture would be the scope to use on the G11; I am contemplating using a 6 inch f/9 and extending the dew shield a couple of feet with heavy paper, thus making the blue sky as small as possible...
Similarly, a simply designed narrow FOV EP worked better in my trials today, ie a TMB supermono rather than a Nagler...the additional FOV only gets in the way (although it might be nice to have with the moon's limb in view).
Any suggestions or errors in my logic will be appreciated.
