Anyone have any favorite variables in Orion? I have tracked W Orionis and BL Orionis for a while. These stars could be for binoculars or telescopes for visual observations.

Hello, Preston. 

 

There are 2 variable stars which I know of:

 

1. U Orionis is a M class star which varies between +4.8 to 13.0 in magnitude.  

 

2. RT Orionis is a C class carbon star which varies between +7.7 to 11.8.

 

Please have fun with them. 

 

Clear skies, 

 

Aubrey.

Preston, are you observing visually or with a camera? What’s your minimum magnitude limitation?

Visually. I would guess my limit magnitude naked eye is around 4.5. I can just make out the Milky Way when my neighbors turn off the darn yard lights.
