M27, Dumbell Nebula using Ha and OIII narrow band filters 2010-07-10 Chris Rowland  
From: Wycombe Astronomical Society Members  Wed 21 Jul 2010 02:55:26 AM CDT
Good shot Chris and interesting approach to colour mapping. By your selection of short exp time and slightly eggy stars, I guess it's unguided? Bring on that autoguider! Alistair

From: Wycombe Astronomical Society Members  Wed 21 Jul 2010 05:06:02 PM CDT
Thanks Alistair.
I'm afraid it's guided, sorting out the guiding is one of the things I need to do next.

Nice Image! It hadn't occurred to me to look for protoplanetary disks.

An appropriate pun David, and a very nice result.

Hi David,

You are getting some good images with your little 80mm refractor.

A nice image Sandy. I did not see it before the Practical Evening on Thursday. You must be pleased with the new imager.

A really nice image David.

M42 taken on 10th Feb 09 with Williams Optics 80mm, .8 focal reducer and Canon EOS450. Various exps stacked in DSStacker and Pshop6. David  
From: Wycombe Astronomical Society Members  Thu 12 Feb 2009 02:34:50 PM CST
That's good David, you are getting more red in the nebula than I can manage, you haven't removed the IR filter have you?
Which focal reducer are you using?
Chris

From: Wycombe Astronomical Society Members  Thu 12 Feb 2009 03:44:41 PM CST
Hi Chris. I used the WO 0.8 focal reducer, designed for the 66mm 'scope but works ok with the 80mm. Lots of exposures ranging from 45" 1600 to 4" at 400 ISA, Final image was quite low noise so I could increase saturation and contrast to make up for L Pol and low red sensitivity.


 

NGC 2392- Narrow Band Image - CFHT Palette 2009/01/20 L-50mins, R(Ha)-40mins, G(OIII)-40mins, B(SII)-40mins. Fred Stevenson Andalsnes Observatory  
From: Wycombe Astronomical Society Members  Sun 25 Jan 2009 02:05:25 AM CST
Hi Fred, This is the same data as the Hubble palette image isn't it? It seems sharper and shows more structure.

These narrow band images give very good results, must save up and get some filters and a filter wheel.

Chris

From: Wycombe Astronomical Society Members  Thu 29 Jan 2009 11:53:50 AM CST
Yes, Chris, both images were produced from the same Astronomik filter data. The True Technology filter wheel is indispensable, expensive but well engineered.

Nice one Sandy; was this with the scope in Alt Az mode?

From: Wycombe Astronomical Society Members  Fri 17 Oct 2008 03:30:23 AM CDT
Yes, Alt Az. Who's asking? Sandy

From: Wycombe Astronomical Society Members  Fri 17 Oct 2008 09:13:16 AM CDT
It's Chris.

Nice shots David. Live view focus must be working well - Alistair

From: Wycombe Astronomical Society Members  Tue 26 Aug 2008 08:04:11 AM CDT
Two nice pictures David. It must be so much easier with the live view on the 450D.

Jan

From: Wycombe Astronomical Society Members  Wed 27 Aug 2008 01:49:10 PM CDT
It certainly saves time Jan, although focussing with the 400D is not too difficult if you focus on a bright star near the target object and then take a short exposure to check on the camera screen. David

What a lovely image. I can see 5 stars in the trapezium.

M42 7 * 180 secs Canon 400d prime focus f10 Meade 2120. Guided. Stacked with DeepSkyStacker, Processed with Photoshop. Tim Scott 1/2/08  
From: Wycombe Astronomical Society Members  Sun 03 Feb 2008 03:37:44 AM CST
Nice couple of images Tim. I suppose the lack of red is because the filter on your camera is cutting out the red H alpha light and we are seeing it in H beta. Baader do a replacement filter that passes the Ha and the brave can take their camera apart and replace it.

Horsehead and Flame nebulae 2008/01/07 ART429, Oynx80EDF Chris Rowland  
From: Wycombe Astronomical Society Members  Sun 13 Jan 2008 10:28:42 AM CST
What a good picture Chris. The horsehead is so clear and obvious. I don't understand all the processes you have used, but I like it very much. Well done!

Good one David - it's a difficult object for a small aperture, DSLR and light-polluted sky

From: Wycombe Astronomical Society Members  Fri 05 Oct 2007 09:45:04 AM CDT
Wow this definitely gets the prize for the most exotic object. Well done. What scope did you use?

From: Wycombe Astronomical Society Members  Fri 05 Oct 2007 09:48:58 AM CDT
Funny - my name didn't come out above - comment's by Alistair

From: Wycombe Astronomical Society Members  Sat 06 Oct 2007 03:03:20 AM CDT
Imaged through 14" SCT - imaged following request from BAA Deep Sky Section Director as fading of this nebula had been reported - there will probably be a report in December's BAA journal.

Another good picture Chris. What is ART 429?

Rather a hazy night and a lot of camera noise. Better luck next time!


 

M27 - Using ART429 and Society's LX200 Taken at the Perseid Barbecue, 12th Aug 2007 Chris Rowland  
From: Jan  Mon 13 Aug 2007 02:43:24 AM CDT
A very nice photo Chris. The shape of the dumbell is very well defined. I see that most of the frames you took were selected for the final result.


 

M27-Ha OIII Bi colour narrow band image 2007/07/31 - Full Moon Fred Stevenson Andalsnes Observatory  
From: Chris  Fri 03 Aug 2007 02:55:17 PM CDT
Hi Fred, Can you say a bit more about the filters, exposure and processing you used. It is with the DSI I suppose, not the colour one with narrow band is it?
I've just got my CCD camera going and will be looking for ideas I can steal :-)

From: Fred  Sat 04 Aug 2007 01:05:27 PM CDT
DSI Pro camera B&W) - 2 images of approximately 15 minutes each taken through Astronomic Hydrogen Alpha filter and Astronomic Oxygen III filter. Processed in Photoshop - synthesised green layer.


 

Rosette neb 7th April. WO 80mm, .8 focal reducer, LP filter, Canon EOS 400 10x 2' exp. David Godwin  
From: Chris   Thu 12 Apr 2007 03:56:17 PM CDT
Very nice, much more subtle than many versions of this.
Is this guided? If so how are you doing it?
C

From: Wycombe Astronomical Society Members  Thu 12 Apr 2007 04:41:52 PM CDT
They were un-guided exposures. Perhaps the wide field of view minimises star movement. Jpeg images from the camera showed no sign of the nebula but the RAW files, with increased exposure, did. d

From: Jan Dell  Mon 28 May 2007 02:49:50 AM CDT
What a lovely image David.


 

M42 Lx200 10" Canon 300d Paul Millington  
From: Jan  Sun 04 Feb 2007 12:18:39 PM CST
Not sure who took this photo. It was taken on the Friday night observing evening, so could be either Paul or Sarah. I guess it is Paul. If so, it is a very good effort for a first attempt. I hope mine turns out as good when I come to process my M42 pictures. Well done!
