Starship Asterisk*

I'm so sorry. Is not this version. I'm going to editing it

Edited. The photo is two photos. One for the sky and other for under. Each one with your correct exposure. Is the first time that i join 2 images. Sorry for imperfections. Also, I don't speak english very well, sorry!

Regards.

NGC 281 the Pac Man nebula is an emission nebula in the constellation of Cassiopeia about 9,500 light years from Earth. NGC 281 is home to IC 1590, a star cluster, and several Bok globules. Bok globules are areas of dark, dense dust found in HII regions. These dense areas ungo gravitaional collapse which in turn forms double stars or multiple star systems.

Just four hours after the blazing fireball lit the sky in Southern California on November 6th, another Screaming Greenie flashed through the night sky near Gemini. For reference, the pink/magenta star top left third is Lambda Geminorum (λ Gem.) Love the rooster tail on this one. Single frame. Starfield is full camera FOV. Detail image is crop at 100%.(next post) Minimal post-processing - pretty much in-camera. Tucson, AZ, November 7, 2013 12:42:52 am MST (7:42 am UT).

Almost no images show this outer halo! It was discovered in 1998 and you can read the discovery paper here: http://cdsads.u-strasbg.fr/abs/1998RMxAA..34..117M
Possibly the only other amateur image that shows the halo is this recently released image by the CHART32 team: http://www.chart32.de/index.php/object-list/ngc-7009

Copyright: Ian Parr Ah ... Comet Nostalgia. Memories of an exposed perch on wind swept North Head Sydney at 9:13pm on 20th Jan 20107. Shunning the wind break for the field of view, I wrapped myself bodily around the mount and hung on.
A few frames made it. This was my favorite.

Hardly any images of any planetary nebulas show the outer halos. I have found quite a few in the Hubble archive which show a chunk of the halo but often the halos are cut off and I end up cutting them off when I process them, too. The Ring Nebula and the Cat's Eye Nebula were both captured and their halos were included but one nebula which seemingly serendipitously had its entire halo imaged was IC 4593. It's really a shame because without the faint, outer, oldest details of the nebula, it's like you're only getting part of the story.

This is DSS2 image data of the region just north west of Epsilon in Cassiopeia. You can see a clear large Lambda, and in the "toe" of the large Lambda you can see a smaller Lambda. So unlike the other "Lambda-Lambda" asterism which is made up from a Lambda and a star, this one is made up from two Lambdas

Galaxies througth the window of dust

Already in 2012 I once discovered "in passing" these galaxies for me.
At that time, only one shot in 15 minutes but i could already see some interesting things.

But not only the galaxies in many different types themselves - also the Galactic cirrus clouds have motivated me a lot of time to invest .
So the great big galaxies are seen in a "window" through the Cirrusclouds.

There are a total of 500 minutes luminance and also at the same time in RGB.
But it has paid off and in my opinion makes a good picture.
The depth of the image (SDSS catalog) is reaching to mag 23 ( easy to see in original resolution )

NGC 346 is a nebulous cluster about 210k light years distant on the edge of the Small Magellanic Cloud in the constellation Tucana. NGC 346 is often described as a stellar nursery and in this image, one can see stars being born in the caldera of a stellar volcano.

Timelapse of Dazzling Comet ISON and Lovejoy
http://www.justinngphoto.com
Copyright: Justin Ng


A timelapse video showing the journey of C/2012 S1 (ISON) and C/2013 R1 (LOVEJOY) on 11 November 2013. The video covers 50 minutes of imaging time for ISON and 90 minutes of imaging time for Lovejoy. From the video, you can see the reduced visibility of Comet ISON and Lovejoy as the sky was becoming brighter gradually.

A new possible ion tail emerging from Comet ISON was first observed on 4 November 2013 and ISON's growing dust tail now stretches to more than a full moon's diameter. Comet ISON is now plunging towards the Sun with 2 long tails at a magnitude of around +7 and it is visible in small scopes and strong binoculars. Comet ISON is in front of constellation Virgo this week and it is expected to grow some 2.5 times brighter before it meets Spica, the brightest star in Virgo on 17 November and 18 November.

Comet Lovejoy just passed into the constellation Leo with a magnitude of around +6 and it's an easy binocular object. R1 Lovejoy will remain well placed at 50 to 60 degrees above the northeastern horizon before sunrise through this week for observers from near the Equator.

The comet appears to be moving fast because of smaller field of view and long exposure. Comet ISON was captured using Luminance channel only so I could acquire more frames before sunrise. I have also developed my own web tool (justinngphoto.com/astro) to check weather condition in Asia region and predict the amount of imaging time I have before I head out to hunt for the comets.

OMG I'm speechless!! This is one of my favourite hidden areas of Andromeda and also one of my favourite Arps. I came across it in 2008 whilst I was obsessed with the Arp Atlas. I didn't know there was a large dust cloud, an incredible surprise!

You're right that nearly all Hubble images of planetary nebulae don't show the outer halos due to the small field of view of only a few arcminutes as outer halos can extend for great angular distances, even as much as 40 arcminutes in some cases!
However there are many amateur images that show outer halos around a great variety of planetary nebulae due to their larger field of view. It's interesting to note that what was once considered to be rare is actually fairly common.
As an excuse to include a list, here is a list of a few amateur images of planetary nebula halos:

1. NGC 7662 by Adam Block: http://www.caelumobservatory.com/gallery/n7662.shtml
2, NGC 6826 by Capella Observatory: http://www.capella-observatory.com/Imag ... GC6826.htm
3. M97 by Johannes Schedler: http://www.panther-observatory.com/gall ... X_cass.htm
4. NGC 2438 by Adam Block: http://www.caelumobservatory.com/gallery/n2438.shtml
5. NGC 3242 by Marco Lorenzi: http://www.glitteringlights.com/Images/ ... -NH4CpPn/A
6. Hen 2-111 by Don Goldman: http://www.astrodonimaging.com/gallery/ ... ?imgID=256
7. NGC 7009 by CHART32: http://www.chart32.de/index.php/object-list/ngc-7009

It is likely that some new halos will be discovered in the future by amateurs as a greater number and variety of different planetary nebulae are imaged!

Not rare at all, nope. I've been using Balick's PNIC page for reference. Not the prettiest of pictures but pretty comprehensive.
