I'm always prepared to forgive a dumb machine. Nobody told it any better.

Comet C/2012 X1 Linear had a strong outburst a few days ago, is increasingly similar to 17 p Holmes.

This is a crop of a two-camera, two-panel simultaneous imaging session that ran over a few days and is my first post.
I have only been in the hobby for 3 years this month and it has been horrible waiting here for clear skies. I am finally happy with the stars in a narrow band image and I think this picture shows what is possible with narrow band imaging even from heavy light polluted skies. It gives me hope that despite not living in the country, I might be able to get good results! Here are links to the full size and other processing results:

Not happy with the wider field, but it looks good from a distance Done with a Canon EF70-200 zoom with H694 camera imaged simultaneously using Baader NB filters and inserted detail from the Takahashi / Trius 814 image:

October 18, Moon and Moondogs, by Ralph Clements
Full moon rising accompanied by, I guess they'd be called "moondogs'....The bluish light at top over the Moon is lens flare, but the moondogs to the right and left of the Moon were clearly visible unaided earlier the evening of October 18, 2013 for 30 to 45 minutes here in southwestern Virginia

It's probably just a copy and paste from the Astrometry.net solver, Nitpicker. Computers are awesome like that.

Dear nitpicker and geckzilla,

indeed - the astrometry results were taken via "copy and paste" from the astrometry solver
It is a good idea to reduce some computational overhead (regarding the precision).
Thanks for watching and your feedback.

Hi Michael. I'm unable to get to the full resolution image because you provide instructions - "Press F11 for a Full Screen view" - rather than a link. For those of us who don't use the same OS you do, a link is greatly appreciated.

F11 is the standard keyboard shortcut to put a browser into fullscreen mode. I don't think he meant for it to show a larger version of the image. If you scroll down on his website there are other sizes available at the bottom of the description text.

Deer under twilight stars

Managed to get the deer's attention just enough for it to stand up but not run away before the stars disappeared behind the clouds.

Ah, way down there. Beneath all those links to his hardware suppliers. Silly of me not to look there. (I did search, all over the page, or so I thought. I'm used to doing that on the many sites that don't make their links obvious.)

But no, F11 on a Mac does not cause a full screen experience. It's Command-Shift-F in Firefox, can't find that command in Safari, while Opera has something called Presentation View, also accessed as the Firefox command, but it seems impossible to get out of it once in. It is naive to count on F-keys being standardized across platforms, or even across applications on one platform.

Rob

[geckzilla]

I don't know why they wouldn't use F11 for a Mac. I mean, they have F keys. For a PC F11 works for Chrome, Firefox, and IE. I haven't bothered to install Safari or Opera. Sorry the software differs on your platform of choice. I suppose there is some odd reason why they chose to do that. Back when I used a Mac I could have sworn F11 worked then, too.

By searching for some papers on the internet I was able to find databases giving the coordinates of red and yellow hypergiants, post-red hypergiants (supernova progenitors), Wolf-Rayet stars, variable stars and globular clusters in M33. With pixinsight I overlaid these on the M33 image to show the different kinds of stars visible in the image. It’s astonishing how many separate stars can be distinguished with a 14 cm refractor nowadays.

The morning skies this fall are graced with several moderately bright comets. Here are four taken the morning of October 27 within hours of each other from the same site using the same equipment and exposure.

Tubular Explosion in SH2-129
Copyright: Lee Buck
http://lbuckphotos.smugmug.com/Astrophotography

This strange object is Ou4 (aka The Squid) in Sharpless2-129.  It was discovered by French imager Nicolas Outters in 2011.  Initially, researchers thought it was a planetary nebula but that has been ruled out and its origin is still under investigation. FOV here is about 100x70 arcmin. North is to the left.

Uh oh, Starsurfer might need new pants after that one, Lee.

Wow, that's fantastic, elbee!!!

At least I have managed to identify the bright blue star inside "the Squid". It is HD 202214, and it is classified as B0V.

The amazing picture looks both like an HaOIII image and an RGB one. Tell me, if this had been a pure RGB image, would the strange tubular extension have looked all red then?

Ann

[elbee]

thanks for the kind words. if this had been an LRGB image or even HaLRGB the squid would not be visible. it was picked up with 13hrs of 3nm OIII data.

here is an intermediate result showing an animation between some Ha data and OIII data -- nothing in common. and none of it was visible in the LRGB data.

[rstevenson]

An amazing image Lee. And that animation makes even clearer how much work goes into one of these "pretty" pictures. Thanks.

[Beyond]

Just goes to show how easy it is to miss something hiding right in front of you, like 's, for instance, or big spacy thingies like squids(?)
