Observing Report 16th-17th November 2017 (Leonid meteors session 1)

Over 650 pics... more than a few planes, but few meteors.
I'll post separate pics of them later, but for now here's a time-lapse of 60-second frames compiled to play at 2fps.
One Leonid at 02:33:24 and one sporadic at 06:26:04
It's best viewed in full-screen after it has finished buffering.

Canon 1000D, 10-18mm zoom @ 10mm, F5.6, ISO 800, captured with APT v 3.33 (http://www.ideiki.com/astro/)
Post-processing with PS CS3, Irfanview, K3CCDTools3 and VDub.

Over 650 pics... plenty of clouds and more than a few planes, but only two Leonid meteors.
I'll post separate pics of them later, but for now here's a time-lapse of 45-second frames compiled to play at 2fps.
Leonid meteors at UTC 03:05:12 and at UTC 05:00:15

Observing Report 5th-13th August 2017 (Perseid meteors)

Posted by on August 22nd 2017 in Astrostuff, Observing Reports, Pics

From the 5th to the 13th of August I managed four nights watching and photographing the Perseids. 1799 pics later and I'd caught nine good meteors on camera, and I'd seen about 75 while lazing on the garden bench. Bearing in mind the low hourly rates, several bouts of cloudiness and the rising Moon, nine on camera is about as many as I would have expected.

Here's the best pic of the bunch, captured on the 12th - looking towards the zenith, West is more-or-less downwards. Click it to see a bigger version:

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.

More of the jigsaw should follow soon.

Observing Report 17th April 2016 (Unexpected sunspots)

It's hard to believe that it's been over a year since I posted anything astronomy-related.

I'm not yet ready for full nights up in the obsy, but unexpectedly I was allowed out to play during the day.

Here are a couple of sunspot pics and a stitched image from a session a couple of weeks ago. Not my best work, but it was fun trying to remember which wires connect what to what, and which software settings are best for the conditions and the data.

Observing Report 22nd-23rd August 2014 (Andromeda cover-story)

Posted by on September 2nd 2014 in Observing Reports

I have a book which was a gift from Chris and the kids a few years ago, a fair while before I bought a decent telescope and started down the slippery slope of astro-kit buying.

I remember looking at the Andromeda Galaxy image on the back cover and thinking "I'll never be able to get images anywhere near as good as that":

 

Title: UNIVERSE
Publisher: Dorling Kindersley Publishers Ltd (6 Oct 2005)
ISBN-10: 1405310715
ISBN-13: 978-1405310710

 

Well...

 

Andromeda Galaxy (M31).
Subs: 35 light @ 300s, darks and bias frames, ISO800.
1000D on the C80ED-R refractor, guided with PHD.

I doubt that it's cover-worthy but I'm chuffed with it anyway.

Another night or two of imaging should provide enough additional data to allow me to reduce the noise and tease out more of the finer details.

(Late) Observing Report 13th-14th March 2014 (Another Moon Mosaic)

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:

Moon (13/03/2014 @ 22:00 approx). 26 panes stitched with iMerge.
Each pane is ~300/~3000 stacked frames. DMK mono CCD camera

Observing Report 14-15th November 2013 (doing a runner)

Posted by on November 19th 2013 in Astrostuff, Observing Reports

Like I said, there was a run of clear frosty nights. I managed to blag a pass to spend another one of them in the shed. No visual observing this time, I fancied a shot at imaging an intriguing bunch of nebulae - NGC 1973/5/7. I could have done better with more subs, so I might well grab some more and process the thing again some time, but for now here's the result:

NGC 1973/5/7, 15th November 2013.
Subs: 25 light @ 300s, 50 darks or bias frames, ISO800.
1000D on the 6" R-C, guided with PHD.

This trio of objects isn't called the "Running Man Nebula" without good reason!
