Instrumentation for Visual and Photographic Photometry of T CrB

Hi All,

Now that T CrB is in the Western Sky after sunset, and from my location it is fading fast in the glow of Los Angeles, I have a new configuration to share. I set-up a visual and photometric photometry scope side-by-side using a Losmandy DVSBS.
This is an Explore Scientific ES102ED & an ES152ED on the Explore Scientific/Losmandy G-11 w/PMC-Eight computer drive.
I’ve started getting familiar with the camera, filterwheel, and NINA, but its been a long learning curve.

I do visual photometry nightly on T CrB and other variables using 120mm binoculars. I’m in Southern California and my visual limiting magnitude is 4.0. So I need 120mm binoculars to easily see 10th magnitude and as the stars move west, they move over the glow from Los Angeles.

I will use the ES 152ED for visual photometry as T CrB sinks in the west. I don’t want to miss the outburst. My giant binoculars will perform well for another couple weeks, but then the western glow will overwhelm 10th magnitude.

This may be “silly” question but anybody else obsessed with T CrB these days?
