Today, despite my legs still feeling the introduction of hilly outside running, I beat my 5km PB by a ~50 seconds!

First outside run of the year, first 5km of the year, first time running up hills in 6 months.

Ran 40 seconds slower than my end-of-summer PB. Very happy with that as a starting baseline.

Last night was very clear, great seeing.

Given the last picture I posted of Jupiter a few days ago, some people were curious about what could actually be seen through the telescope v.s. what came out in image stacking / compositing.

So here is a direct capture from the telescope last night showing Jupiter at regular exposure (so you can see the moons), and then I cranked the exposure way down to reveal the atmospheric details - which came through amazingly.

My long term goal for the year is to get that 1.5 mile run down to 15:00 minutes , which would be 6mph / 9.6 kmh (for reference 17:46 is just a smidge over 5mph / 8kmh )

Pretty confident that is within me physically -the biggest challenge will be convincing my brain that my body can sustain that.

My goal this morning was to beat my previous 1.5 mile run attempt which stood at 19:00 minutes - with an optimistic target of 18:00.

Final 1.5 mile time: 17:46!

Slowly getting faster.

For those asking:

Telescope: 130mm Newtonian
Camera: Very basic telescope camera hooked up to my tablet, running a very based usb camera app.

Image of Jupiter was compiled by taking 5 frames from a video recorded at the lowest exposure setting ~5ms (atmosphere disturbs a lot, so while I could make out the banding in real time, the finer details require sorting through the frames to find the good ones) - have a few videos unprocessed so likely have better frames left to work with.

Woo my first time resolving Jupiter's bands!

Also please enjoy this capture of a sat flying past.

Camera telescope testing last night, wasn't the best seeing, but I always love a taking a nice photo of Jupiter + moons.

I did some maths, the bird was between 20 and 30km away, assuming a wingspan of around 1.5m - 2m.
