Planet Jupiter Visible?
Discussion
Was closing the bedroom blinds about ten minutes ago and noticed a bright star next to the moon. The sky is still fairly light and perfectly clear with no other stars visible so I downloaded an app to find out what it was which suggested the star is actually the planet Jupiter.
Any space experts care to confirm?

Why don’t you believe what the app is telling you?Any space experts care to confirm?
Topically, taken this very evening....
Finally got to try out my new shiny Sesto Senso USB focuser on the 300PDS - being able to fine tune the focus remotely, much less hassle. Nearly gave myself a heart attack getting the bloody telescope off the mount though - it's stupidly large, weighs 25kg and was covered in dew. If the weather stays clear tomorrow, back to more sensible equipment.

If you missed Jupiter beside the moon last night, have a look at the moon tonight and you will notice what appears to be a very bright "star" to the right of it. This is the planet Jupiter.
Almost the same distance to the left of the moon is a less bright "star" with a reddish hint. This is the ringed planet Saturn.

That's a fantastic picture, I thought though that Jupiters stripes would appear horizontal from Earth, I thought they were on the same plane as the planets or only just off centre of that plane? Or is it the angle of the camera mount on the telescope. Amazing how faint the moon is, but also how large it is in perspective. Again, fantastic picture.Finally got to try out my new shiny Sesto Senso USB focuser on the 300PDS - being able to fine tune the focus remotely, much less hassle.

As it happens, I think the scope had gone out of collimation slightly as the focus is off in the source video - here, if you're interested, 300Mb AVI - despite my best efforts tweaking it with the autofocuser. I had collimated the scope earlier in the day when I set it up, but I think I should have redone it just before imaging, as the thing had cooled signficantly since the evening. There are some absolutely fantastic Jupiter images which other folk have got with similar kit, but that's the best I've managed so far.
I also hadn't checked the Jupiter moon movements earlier, otherwise I'd have kept imaging - the moon is Io, and there was a transit about half an hour after I'd packed up, and in principle the shadow should have been visible on the surface...

As above, it's just the angle of the camera. The stripes are maintained by Jupiter's very rapid rotation (just under 10 hours to do one revolution), and yes, that rotational plane is pretty much in line with its orbit around the sun (off by just a degree or so). If you have a telescope powerful enough to resolve detail in the stripes, you can watch them rotating over an hour or so with a stopwatch.Other sites are available, but this rudimentary but effective site will calculate the four main Jupiter moons for an arbitrary date and time...

Anyone know of some decent software to covert a video into an enhanced still.
I have a mead LX10 in the back garden with a usb webcam attached. Trying to get some decent post processing done.
Registax is getting on a bit now, has issues with large files, but is fairly straightforward to use, and has wavelet sharpening integrated:I have a mead LX10 in the back garden with a usb webcam attached. Trying to get some decent post processing done.

Now common for people to do video stacking in Autostakkert, and then do the wavelet processing on the resulting still back in Registax.

Double edited: Not sure what capture software you're using, but both Sharpcap (https://www.sharpcap.co.uk/) and Fire Capture (http://www.firecapture.de/) are well regarded. The £10 annual fee for Sharpcap Pro is an absolute bargain IMHO, and has good integration with Zwo cameras (I've been using a Zwo ASI120MC-S for finding / guiding, and either an ASI290MC or ASI294MC Pro for imaging, the Jupiter shot above using the ASI290MC)
