Observing Report 16th-17th October 2016 (coloured Moon mosaic)

Posted by on October 20th 2016 in Astrostuff, Observing Reports

Moon-gazing again last Sunday... playing around with a colour video camera on the 6" R-C... 17 clips each of 250 frames, stacked with AutoStakkert!2, coaxed into one mosaic using iMerge (see previous post), tarted up with Photoshop CS3.

The result is better than expected.

Feel free to click on it to see the full version, but be aware that it might take a while to load - it's about 12Mb:

 

If that's not enough, there's a ~40Mb .bmp version here.

One edge done

We've now got all of the bits, they're fitting together nicely:

 

Should be finished soon.

"The moon is essentially gray, no color; looks like plaster of Paris or sort of a grayish beach sand."

More of the jigsaw should follow soon.

There's not much to report here, no stargazing was done - poor seeing and too much haze for visual observing of faint and/or fuzzy targets. The Moon was about the only thing worth pointing the scope at. Suffice to say that 26 slightly hazy .avi files were taken, stacked, trimmed and stitched to make this image:

It was going to be a night for software-testing, there having been a new release of APT that needed checking out. The skies were clear but the heat of the previous day was still making its escape from the planet via the air, which meant that the seeing was marginal for any sort of imaging, therefore I wasn't intending to take any images.

And then I remembered the medium-bandwidth Hydrogen-alpha (H-a) filter that I'd bought on the cheap. In theory it would cut out the worst of the shimmer. It had to be tried.

It worked, and it worked better than I would have expected. I grabbed 22 .avi files of the Moon, and after a bit of stacking jiggery-pokery I stuck the resultant .bmps into PS's photomerge. That spat out a reasonably-good mosaic image which I processed with RegiStax, and the following image was the result. I'm reasonably happy with it, but there's room for improvement next time out:

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

Posted by on June 4th 2013 in Astrostuff, Observing Reports, Pics

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:

DMK mono camera @ prime-focus on the 6" R-C.

 

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

 

Moon (27/05/2013).
28 panes stitched with iMerge. Each pane is 500/2000 stacked frames.

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)

Posted by on December 1st 2012 in Astrostuff, Observing Reports

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:

Observing Report 2nd-3rd and 5th-6th November 2012 (Addendum)

Posted by on November 16th 2012 in Astrostuff, Observing Reports

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:
