Observing Report 26th-27th May 2013 (The Great Eye)

It had been a while since I'd pointed the scope at the Moon.

These pics show my favourite phase - 2-3 days past full - when the terminator runs down the eastern limb and highlights a string of craters and maria.

Here's Mare Crisium - the Sea of Crises - looking like a huge lidless eye staring into the void:

 

Mare Crisium (27/05/2013).
DMK mono camera @ prime-focus on the 6" R-C.

 

And here's a poor effort at a clickable mosaic of the whole shebang:

 

Moon (27/05/2013).
28 panes stitched with iMerge. Each pane is 500/2000 stacked frames.
DMK mono CCD camera @ prime-focus on the GSRC6M.
The seeing was bad so the detail isn't as good as usual.

It isn’t a bird, it isn’t a plane…

I caught this thing on video while out shooting the Moon with my telescope this morning.

This clip is a 10fps cut from a 1-minute video, originally 60fps.
No post-processing apart from the addition of frame times and numbers in VirtualDub.

Telescope: 6" f/9 RC Astrograph - 152mm Aperture / 1370mm Focal Length.
Camera: DMK 21AU04.AS (Sony ICX098BL CCD chip 640 x 480 pixels @ 5.6 µm x 5.6 µm).
Calculated FOV: 6.7 x 9.0 arcmin.
FOV centre: Alt: 17 deg, Az: 178 deg, RA: 18h, Dec: -21 deg

I'm trying to work out if it's a satellite, a rock or just space-junk.

If I figure it out, I'll let you know.

Observing Report 29th-30th November 2012 (Another coloured Moon)

I was out Moon-gazing again the other night. It was so damned cold that I didn't feel the need to use the camera cool-box, the sensor was well below zero throughout the imaging run. This time I decided to get full-frame shots instead of video. With the 1000D on the 6" R-C I took 50 subs with APT, stacked them in K3CCDTools3, applied wavelets in RegiStax and colour-enhanced the result in Photoshop. I reckon it's a bit better than my previous effort:

Nearly forgot about this one!

I was using the Canon EOS 1000D on the 6" R-C scope and trying out the Planetary Mode of BackyardEOS. Using this mode of the software lets me make .avi files which can then be frame-stacked by other software such as RegiStax. The colours are natural, all I've done is to increase the saturation using Photoshop. The result's rough & ready but at least it's a start:

You'll all have noticed the line of lights in the south-western sky at about 18:30 GMT yesterday evening, no?

It's not the greatest of pics but it's the best I could do in a rush:

This is what you get: upper-left = Jupiter, middle = Venus, lower-right = our Moon

The 4th in the line is Jupiter's moon Ganymede (a tiny dot really close to Jupiter, you'll need to look at the full-size pic to find it).

Other folk have also seen Mercury (even lower than and further right of our Moon) from their locations, but from here it was down in the light-polluted clag.

There'll be similar such alignments in the south-western sky for several nights - have a look, take some pics, see what you can catch - here's what's on offer just after sundown on Monday:

Just don't go being stupid and looking directly at the Sun - it's another one of those things that'll make you go blind 😯
