  1. Some nights the guiding is poor, some nights it is good. Tonight it is very good.

    With the RA and Dec curves so flat, I would say it is dead good!

    With a pixel scale of 1.38"/px and assuming a normal distribution, a <0.3" guiding error means that 99.7% of the time (±3𝜎) the total guiding error is less than 1.2 times the size of a pixel on the main camera!

  6. Mountain Hare - from a stroll up the hills today. It was bitterly cold, but the hares were relaxed and allowed me to get close enough.

    Taken with a Canon R5 and RF100-500mm lens.

    Always lovely to see in the Highlands Of Scotland.
