Hi all
Got up again in the wee hours today to get some morning objects. Tried for NGC 1535, a planetary nebula in Eridanus.
http://www.iceinspace.com.au/forum/attachment.php?attachmentid=5158&stc=1
3 x 4 mins ISO 400.
Finished up with a single 6 minute M42 at ISO 1600

Could only take one shot as it was getting light due to dawn!. I stopped at 6 mins because I could no longer see the LMC , it was getting light.
Both taken with baader UHCS filter and Lumicon Coma corrector. 10 inch scope 300D camera.

PS no worries about neighbours turning on outside lights at that time of morning :). generally the sky is a little darker overall as many non essential lights are off by midnight onwards. Cooler temps help the camera too.

Awesome Scott,

M42 is excellent, so is the planetary.

Very very nice Scott.

M42 would have to be the best Neb...am I right saying this.

Hi Scott,

Fantastic M42 for a single 6 min shot. That really gives me hope for an improvement on my M42 from last season. I have the Baader UHCS filter and I hope my Baader MPCC will arrive soon.
What Processing have you applied to the shot? I'd be most interested to find out what you had to do to get it to where it is now.

I think I'll wait until the next dark though (I'm allergic to lack of sleep)

Nice M42, I can see my star is still there at present. Must do a DSO night soon.

Many thanks all.
With M42 I used Gradient exterminator in Photoshop cs by drawing with the mouse a ring round the outskirts of M42, selecting "inverse" then running Gradient Exterminator, with neutral background selected. I then adjusted Levels to darken the sky, saved it as a low compression Jpeg then ran Noiseware on it with default settings. Thats it! Can use Curves in Photoshop to neutralise the sky background too, as with the UHCS filter I get a blue cast to the sky. Neutralising it enhances red in nebulae, making up for some of the loss of h alpha light in the unmodified camera.

With NGC 1535 I stacked the shots manually in Photoshop, then adjusted Levels to brighten the nebula slightly, then cropped it , keeping just the central part so I could show it here at full res.:).

Thanks for the info Scott.

I think this filter is going to be fun!

amazing how smooth and noise free the M42 nebulosity has turned out..Noiseware working overtime or did you hav a reasonably noise free image to begin with?
