Single shot orion nebula

Single 15 sec exposure 1600 iso on canon t3i and 6se with wood wedge.  Eyepiece projection shot on a 25mm widefield.

Great image .

If your signature is right, you took this with a NexStar 6SE with a wood wedge in-place?  Did you build the wedge yourself, or did you buy it?

Obviously did not mean signature, but can not amend the post

Nice. Get 20 of those and stack them, you'll see much more.

Great start.

Yea I built the wedge myself.  Non adjustable so I use to tripod to get aligned and make sure the latitude of my wedge says 41 degrees with an angle finder and make sure I am level.  I could not get more then 30 seconds with the shots as I was not aligned well enough.  I had 7 pics that I had stacked but the image was floating down in my view screen the whole time and images didn't go together that well and shows trailing around the outside edges.  Ill take some pics of my cheap mount next time I am out and post. 

And this is not eyepiece setup as stated before this is prime focus my fault.

Here is an update pic for my orion on my new mount.  1/27/14.

This was a try at the better focus attempt last night and a little bit shorter expsosure.  1:00 minute.  1/28/14

That last photo is beautiful.

Nice work.

[Rudeviewer]

Another single

Thanks.  I am working on getting the scope aligned better so I think tonight will be learn the drift align process in the cold lol.  Like 7 degrees out last night.  I had snowmobile boots on and two pairs of socks and still I was frozen.  So was my scope.  I got some frost build up and that's where the red color comes from in my last picture.  I think 2 min exp.

excellent espacially for sigle subs! stacking would be a great idea!

[Rudeviewer]

I am currently trying to stack using DSS and registax and neither of them will properly align my pics so I get nothing more then blurry images out of both, which stinks because everyone says stack em! lol.

Stunning mate. Nice work.

Fantastic Pic, I have just purchased a Canon T3i (unmodded) myself  to give AP a try, What lens do you use? any tips would be be gratefully received

[Rudeviewer]

_{I use my telescope at the lens actually.  Get a T-ring adapter for your T3i.  Also what kind of scope do you have?  If it is anything like my 6SE SCT you will also need a focal reducer to fit more objects in to your view.  Also to help a little bit with exposure times.}

[Darren7478]

Excuse my ignorance I am a complete beginner with AP, I dont currently have a telescope, yet anyway! I was just go8ng to start with a few moon shots ect... and pick everyone's brains before buying the scope

Good way to start.  Id get a nice sturdy tripod point it up at the sky with a few different lenses and see what times you can get with different iso settings and not wash the image out too much and not get too much star trailing.  If you have wide angle lenses you can try a wideview shot. 

I am a total newbie myself when It comes to AP, but I think I have a good basic start to imaging.  Getting my scope drift aligned and holding the image in a high magnification now is a different story lol.  Practice practice practice. 

[Darren7478]

Again at the moment ive just the standard kit lens! Gonna have to look through pics and posts work out what to by, but thats what its all about, and the practice of course

Very nice images keep up the good work.

+1 on focal reducer will speed light capture

+1 on Deepskystacker, try more alignment stars %

+1 on t-ring, eyepiece is reducing light

Ingenious on the wooden wedge!

Just a thought on your drift, UK latitude is 51. Check your lat and is your tripod bubble level?

Good stuff keep it up

[Rudeviewer]

I did screw up this last time and not level my tripod before I set everything on top of it.  I did a polar align on rigel and adjusted the tripod, so I missed one step.  Ill make sure of this next time.  For a drift align, I need to also learn which adjustment to make when I see the star drift certain directions.  I am 41 degrees where I am at in Colorado.

I did get the orion starshoot autoguider w/Celestron 50mm guidescope this week but I havn't had a chance to use it yet due to ordering it and having clouds sent my way lol.

[Christopher Davenport]

Sorry, missed the location. Good stuff.

[Rudeviewer]

Thanks for the compliment!  Will keep up on it.  Im hoping for clear skies tonight but I think were calling for snow.  DOH!

Some simple propcessing would help. Two key things jump out.

1) The black point.

2) Colour balance.

They are related. If you have Photoshop or similar, have a look at the histogram (Open Levels) in each colour.

The top left of the peak should line up in each colour channel. To adjust them, take the colour with the peak furthest to the right and drag the left hand slider to the right until the relevant peak lines up. Try not to clip off more than you need. 

Then when the colours are balanced you can go to RGB in levels and maybe clip a little more off the left hand side, but don't be too aggressive. The night sky isn't jet black.

Olly

Histograms are one thing I have just barely started to mess with.  I will make sure to check each level to start off with now that you have given me this info.  Thanks!
