My deep sky images with DSLR

Recommended Posts

I started astrophoto 18 months ago, and after one year of leaning I begin to like the results.

This are some of the images I made this year.

Orion Nebula: 23x30' + 23x2' + 12x5' + 16x8' --> 4 hours

M81 +M82: 29x5' -->2.5 hours

Blackeye Galaxy: 37x5' --> 3,1 hours

NGC 2403: 32x5' --> 2,65 hour

M101 : 10x15' Ha, 39x5' RGB --> 5.75 hours

M101 Combined image (RGB +Ha) with a friend Emil Kolbert.

Setup: custom Newton 8'', NEq6 Pro, Canon 500Da (Baader filter), Guiding St80, ALccd5, Phd.

(Sorry for my english because is not my native language)

I would like to see your opinion, advices, please...

Thanks.

All RGB images are made with DSLR except the 10x15 mins Ha subs of M101, wich have been blended to red channel.

This were made with this setup

TS ED 90/500, Nova CCD 1602E, H-alfa 6 nm, EQ 6 Pro.

Super set of images... The M42 image in particular very nicely processed

I have been holding off modding my 500D...

These are outstanding efforts, love the detail in M64 and M42+Running Man blue nebula is wonderfully caught. M101 is a bit noisy compared with the others which are smooth, how did you blend in the Ha?

Thanks...

The M101 is noisier because it were 2 very hot nights when I imaged it with more than 15 degrees Celsius. The other images were made in cold nights.

In M101 image I put Ha image in a layer with 30% opacity, blending it on the red channel.

Sorry for delay.

Congrats on the great images, the colour M42 is my favourite, not just because of the processing, but I think it's a very beautiful picture as well.

Roll on winter and M42!!

There great images, especially also because they are taken with a DSLR...brilliant work, I'm also running down this route at the moment "Custom Newton" by this weekend everything should be finished, fingers crossed.

They are very good images indeed. M42 is a hard object and you have done a great job on it. There is a plug in for removing green here. (Hasta La Vista Green)

I find it very useful, or rather I use a similar thing in Pixinsight. I thnk it would help your M42 to become even better.

Welcome to SGL Psemil and what a wonderful set of images in such a short amount of time. I especially like the M42 image with good detail all the way to the core.

Regards

Kevin

Thanks again for appreciation Kevin.

Olly I did a noise reduction in Pixinsight (acdnr) but I will try this plug-in in photoshop to see if I can make M42 image even better.

The hard part for me was to process them the right way, and resist at -15 degrees celsius near the scope for many nights. :BangHead:

Ah, if you have PI just try the green remover called SCNR. The default setting is for green. I find it brilliant.

Interesting diffraction spikes around the stars in the M101 picture. Why is this?

Great images, very impressed!

18 months? I think I might just give up now.

As others have said, these are incredible images, made more incredible by the fact that they were (mostly) shot with a DSLR.

The diffraction spikes around M101, i believe, are mostly made by the holders of the primary mirror and because the image stretching is more aggressive.

Revealing the spiral of M101 is harder due to lower surface brightness of the galaxy. The stretching and the higher ambient temperature the nights it was imaged are the reason for higher noise in my M101 picture.
