Astrophotography – solar system

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! (https://roslistonastronomy.uk/more-domes)

‘Almost’ Supermoon last night

HI Folks

*Update – sharpened the picture very slightly in PS ***

Last night was pretty clear for a while so I thought I’d do some prep work so I could get some good images of tonight’s Supermoon (21st March).

Well, as we can all see outside, that’s not going to happen (100% cloud here)

Anyway I got this nice one last night, with the SW 102 and the ZWO 174 camera, stacked in Registax 6 and tweaked slightly in PS

Enjoy !

First Light with my New Old Telescope

I’ve been thinking about getting another OTA to enable me to image at a higher magnification, but been a little worried about whether my mount and guide setup would support it. A few weeks back an old blue tube Skywatcher 200p OTA appeared on the SGL classified section for £50- it felt like a low risk way to find out.

As advertised, the tube has a few cosmetic marks, but the optics all seem to be good. Despite the impending Storm Gareth I really wanted to give it a go last night and see what how it would work. Collimation, balance and focus was easy enough (even though the focuser is a bit sticky), but the semi-cloudy conditions and the gusting winds causing the scope to jump around persuaded me to stick to the moon for my first effort.

Of the pictures below, the full disk is from my 600d with a 0.9 coma corrector; whilst the others are from stacked avi’s on my ZWO Barlowed to x3.2 with a bit of wavelet adjustment in Registax (I wrote that like I know what I’m doing in Registax, which I really don’t!). Finally there’s a little picture of the scope in action to record the moment!

Mercury25/02/19

With clear skies over the next two evenings Mercury makes a good target as it approaches greatest eastern elongation (on27th) visible from approx. 18:15 till 19:00, looking to the west south west and with a good clear horizon, try spotting it with binoculars first.

All images taken with Canon 450D on tripod, cable shutter release , manual focus, all 1600 !SO  with Sigma 150 – 500 mm zoom lens.
