Jupiter from the window-sill 22/05/2019

Early hours & no sleep!

There was the Moon and Jupiter through the window, so I thought I would have a go. For convenience I dug out the old Toucam with X2 and X3 barlows.

I wasn’t expecting much given Jupiter’s low altitude, a low cost ST80 telescope and the double glazing, and I didn’t get that much!

This is the result after wringing as much out of it with GIMP as I could.

I am puzzled by the apparent feature at the far left if the Southern Equatorial belt. I thought initially it was the Great Red Spot, but none of the predictions show it anywhere near there at the time in question. Maybe an imaging/stacking artefact caused by a dust speck? It doesn’t look like it though.

Schroters Valley and the Gruithuisen Domes.

Looking at the Moon from the “window-sill observatory” last night, the lunar phase looked suitable to observe Mons Rumker. Unfortunately the exact phase and unfavourable libration precluded this, but as compensation there was a nice view of Schroters valley and the Gruithuisen domes. Better images of the domes than the last time I tried! (

Hunting the Teapot

I have always wanted to see the Sagittarius “Teapot” from the UK, but never have done. You need a very dark sky and a very clear low southern horizon. Our recent Wales visit gave us the dark skies, but not the low horizon (too many hills!).

Anyway, last night, couldn’t sleep again. One palliative for this is to go for a walk. It was 03:30 AM and Sagittarius was just about culminating, so on with the dressing gown and boots for a trek to the bottom of the garden where you can see a low southern horizon. I also put my camera in my pocket, just in case. I knew where the “Teapot” was – between Jupiter and Saturn, but the Moon was up and it was just beginning to get light.

So, Jupiter and Saturn and Antares were obvious, but could only see the odd star where the “Teapot” was supposed to be – nothing resembling a teapot!

Out with the camera to see if a bit of image processing would show anything. After a bit of fiddling with the exposure, I got an image that might have potential.

So here is the processed image, and I am quite pleased with it. The elongated line near the teapot is a plane. Still haven’t seen the “teapot” visually though!
