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

Built and proudly displayed by Clive VK6CSW

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.

73, Clive.
