Jupiter and Moons
Daniel VK6WE took a sequence of Jupiter over a number of days in September/October 2022. The successive images clearly show the change in relative position of the moons over this period of only a few days.
From Daniel …. Jupiter was closest to Earth for 59 years and in opposition to the sun while there was a new moon making viewing conditions ideal. The photos were taken on successive nights from 28 September at about 10 pm when Jupiter was high to the north east. I used a Fujifilm XT-2 with a 200mm lens. The camera was able to autofocus well but I had to find the right exposure manually.
Well done Daniel.
Tiger Moth Model

It’s all about the batteries.
This model Tiger Moth is powered by the same 250 W brushless motor and batteries I showed you this morning. Two batteries in parallel give a safe endurance of about 15 minutes flying time.
Wing span is 49 inches, flying weight about 2 kg. So far, it hasn’t been crashed! Motor draws about 20 A on take off and 8-10 A in cruise.
A lithium polymer battery, or more correctly lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid (gel) polymers form this electrolyte.
