Orion Nebula 23rd Jan Auto Dob & DFK

[Space Cowboy]

My first attempt at deep sky with the dfk. Quite pleased with the amount of nebula detail. This was a 4 min avi at 5 sec exposure. Dob's tracking not the best for this kind of imaging lol

[Quatermass]

Nice detail in the core you have captured there.

[Spikey]

Stuart you're on the slippery slope now. It has picked up a lot of nebulosity though, very nice for 5 seconds a sub.

[Space Cowboy]

Thanks guys! This is just a temporary filler until Mars and Saturn come around to pre-midnight Simon, the most deep sky equipment I'm likely to buy is a focal reducer Did try 10 sec subs but half the avi was corrupted so it looks like single shot mode is needed for longer exposures. I reckon 10 sec will work ok with a focal reducer. Yeah, the most deep sky stuff I'm gonna tackle is m42 and m31 Chances are so few and far between as the Dob can't cope with any breeze doing this kinda stuff.

Increased saturation. I think this is an improvement though maybe too much colour?

[Space Cowboy]

Another version this time upscaled 150% and smoothed with colour noise reduction which has helped.

[Quatermass]

Have you tried a slight unsharp mask love the colours in there.

[Space Cowboy]

Thanks! Here is a unsharp mask version , had to be careful not to over do it else the stars become exaggerated :

[Quatermass]

Looking good if you want to inhance the colours try using match colour settings slide the colour and luminance settings up after duplicating the image then apply a hide all layer mask and paint the colours back in with a low opacity.

Ok looks like I'm now out of my Planetary processing comfort zone lol That's gone right over my head.

I use Gimp, Image analyser and Paint.net. I'm guessing Gimp would do the process you've just described?

Awesome work from an Alt-Az mounted scope!

[Space Cowboy]

Cheers Mike!

Tried m31 last night but not as successful at this kind of focal length, looks like it needs much longer exposures which this setup is not capable of especially when there is a pesky breeze! Think I will stick with m42....maybe try doing a mosaic.

[Quatermass]

Sorry I use photoshop so dont know about those ones. But if you go through my photoshop tutorials on my blog they will teach you all about hide all layer masks.

Great job, much better than anything I can achieve at the moment.

I'd really like to see how your mosaic turns out.

It's remarkable that you've managed to capture such a clear image without any obvious field rotation. Perhaps a mosaic of this area will turn out fairly well, I'm really interested as it's a great example of what can be done with a little perseverance!

All the best,

Mike

Cheers I will take a look at your tutorials!

Thanks Neil and Mike!
