#7654 Jupiter and nice alignment of the main moons

Posted by Guest on 29 January 2014 - 08:52 PM

By the time I was finished with M82 the cigar galaxy, Jupiter was already starting to set in the west at about only 30-35 degs up! So I did a quick smash and grab!

#7125 Still working on the Helix Nebula

Posted by RickS on 12 December 2013 - 11:58 AM

Working on my Helix Nebula again...  22 hours of Ha, 22 hours of OIII and a smattering of RGB just to colour the stars nicely.  Perhaps a little more work to do but I think it is shaping up nicely...




Constructive criticism appreciated!

#6788 Flying Horse Nebula

Posted by Captain Tweaky on 25 November 2013 - 11:44 AM

Well finally I managed to use my William Optics GTF81 for imaging for the first time a couple of nights ago. I managed just 5x600 Ha : 5x600 OIII : 3x800 SII before the wind knocked the guiding off!! The target was The Flying Horse Nebula (aka The Wizard Nebula) NGC 7380. 
I found the OIII & SII were very faint so the first result is a bit of an unusual colour palette and it is a bit soft. The re-process is a sort-of Hubble Palette very much restricted by the amount of data and lots of lovely 'noise'!!!
Compared to some of the magnificent images that I've just been looking at on the forum, these are certainly a bit 'average'  :(  - but hey - I'm glad to have finally used the 'scope that I bought at an astronomy show very much earlier in the year!!  :)
Yours aye - Cap'n

#5789 Astrophotogrphy for beginners - what not to do?

Posted by Andromeda on 17 September 2013 - 05:12 PM

Hi Neil,

Definately a good article especially for those who are just starting with astrophotography! Thanks for writing this article.
Is there anywhere in the Netherlands or Belgium a place where I could follow a training or workshop astrophotography?

Well I've never used the friend feature here, mainly as i wouldn't want anyone to feel they weren't. And it's something else I'd need to do and I am just lazy.


With that in mind, If you are in the hobby and posting in here - hello friend!  Even if you have not joined and are just reading, howdy fellow astro enthusiast! to those that have joined, Nice to read your posts and happy to meet you here - look forward to future astro-talk via electric ink, and thanks by the way!

This is my most recent, and I think most successful mosaic to date.  If the weather holds tonight I'm hoping to add the pelican.  Four sets of 420 sec lights, darks and flats, merged and processed in PS5.

Posted by RickS on 16 August 2013 - 09:51 AM

A work in progress.  I'm imaging this at 2760mm focal length (f/9) so lots of data is needed.  So far I have 7 hours of Ha and 5 hours of OIII.  Here's a funky bi-colour...

#1974 Barnard's Loop

Posted by Erk1024 on 17 February 2013 - 02:52 AM

Took this one last weekend. I think I need to add some data with an Ha filter to try to separate the nebula from the background more. Should be able to punch up the colors. So, it's kind of a work in progress.


In any case, Orion is a great constellation--so many nebulas to choose from.  :)

#9038 Sh2-129_OU4 in HST palette

Posted by Paramount on 05 August 2014 - 07:54 PM


This has been my toughest target to date mainly because of the extremely faint OU4 (Giant Squid Nebula) that lies within Sh2-129 (Flying Bat Nebula). They are strange objects in that there is Ha and SII in Sh2-129 but no OIII that I could detect and OU4 only has OIII but no Ha and SII. OU4 was discovered in 2011 by French astroimager Nicolas Outters hence the designation OU4 and it is thought to be a bi-polar planetary nebula.

Exposure times are as follows

Ha = 28x10 minutes

OIII = 45x10 minutes

SII = 23x10 minutes

As with all my current images this was taken with the Televue NP127/FLI astrograph that I'm testing on my Paramount ME with auto guiding done by a Starlight Xpress Lodestar on an Officine Stellare Falco guide scope using dithering between exposures.

The image is still a bit noisy which may be resolved by shooting more data but I'm reasonably happy with the result as my main aim was to get the squid to show. The blue channel (OIII) required more stretching than the Ha and SII hence the bluish background and didn't show any detail at all on the downloads or the stacked master frame, it didn't start to show until after the second iteration of curves before colour combining

The full size image can be seen at the following link




Thanks for looking

Best wishes

#8372 Mars again

Posted by Lenny on 28 March 2014 - 10:00 PM

I find the recent events concerning a few posts and the planet Mars very interesting.  We had wrote about the difficulty in observing Mars.  Yet, when all the conditions were right and Mars revealed itself, the results could be memorable.  A few nights after those posts, I had an observing session on which the images of Mars were just great.  I posted that observing session.  I ended my post by writing "I hope there are more opportunities this year..."  I had know way of knowing how soon that would occur.


On 3/26/14 I again noticed the sky looked very good for observing.  It was getting late, and I had to get up early for work so I decided to take out my Orion 80MM F7.5 APO.  I used the following eyepieces:  18MM and 10MM Celestron x cells, a 14MM Meade series 5000 plossl, a 12.4MM Meade series 4000 plossl, a Tele Vue 11MM plossl, a Meade 9.7 series 4000 plossl, and a 9MM Antares Ortho.  Also, I used a Tele Vue 3X Barlow, and a Celestron 2x Ultima Barlow.  I know that is a good bit of oculars, but I find that even the smallest change in magnification can greatly effect the image of a planet.   Also, it is helpful to change the way you produce a specific magnification, IE, a 10MM EP with a 2X barlow or a 15MM EP with a 3X barlow.  At times, even using a barlow/EP combo or achieving the specific magnification with an EP alone makes a difference.


I turned the scope to Jupiter.  It was very clear at 60X, and than at 100X (the 18MM and the 3X barlow).  I found I could push the  mag to 180x (the 10MM with the 3X barlow) without much breakdown of image.  The keys here are clarity and stability.   Since I could see all the four observable Moons, and the GRS was not visible, I decided to turn my attention to Mars which again was rising high above my neighbors house.


I located Mars with the 14MM Meade Series 5000 plossl.  As it has an FOV of 60 degrees it provides very nice if marginally wide views.  With the 3X TV Barlow, it gave a mag of 128X.  At that mag I could make out some surface detail.  Upping the mag to 180X was good, but I lost some detail. So, I backed down to 164X, the 11MM TV plossl and the 3X TV barlow.  At that mag I had some great views.


I could barely discern a light area on the North polar region.  I was able to observe dark markings on both the East and Western areas or the planet.  Between those markings and the edge of the globe was a grayish area the ran from the South polar region up to the mid latitudes.  This observing session was much like the previous nights except the middle of the planet.  There I observed a lighter area without any dark marks.  It had a light peach color.  In the upper left area of that mid region I noticed a small tubular object.  It was about 1/10 of the size of the rest of the middle region.  What made this tubular area stand out was the color.  It was almost white.  For whatever reason that tube was difficult to observe.   When it dimmed I resorted to adverted vision.  I am not sure why this occurred, or what I was observing.  I think it was the result of some type of distortion caused by the planet's atmosphere and  a possible dust storm  because I cannot place a white area in the mid Northern temperate region of Mars.  Whatever I was observing, it was very interesting.


I stayed out later than I anticipated, taking an hour on Mars as again the surface detail was marvelous.  Also, I want to mention my equipment as it performed very well.  As always the Orion APO did a first rate job.  The Tele Vue 15MM and 11MM plossls, the Celestron 18MM x cell, and Meade 14MM oculars provided excellent views.    


It was another nice night.  I hope there are many more to come this year....

#7282 Christmas morning moon.

Posted by tich on 25 December 2013 - 11:37 AM

I was just about to go to bed at 1:00am when looking out of the window I could see that the sky was quite clear & the moon was up so I set up the scope & took some pictures. I have struggled with this one as I have been getting weird artefacts after stacking so cleaned some of those out but I'm unable to remove the ones on the lunar surface. I think it could have been due partly to underexposing it to much so I was having to stretch it quite a bit to brighten it up. Anyway this is the best I could manage.

Taken using a 6"SCT manually tracked on an EQ5 & using a 1000D, 100 subs processed in PIPP then stacked in Registax.

I wanted to do a real marathon on this one, but impatience and cloud beat me and I gave up after 12 hours. I think that the OIII in particular was interesting, I've certainly not seen the OIII cloud by 34Cyg before.
