My little window...

Although, after going through my images, I think I understand where you are coming from Junwei.

This is a single-frame edit of the Jewel Box I caught last night, and it does image better than the stacked sequences:

Wooohooo!

Finally tried my hand at something different tonight!

NGC 3372 aka Eta Carinae (or, as I call it, the Independence Day Alien!)

30sec x 39 frames @ ISO800, Canon EOS 1000D (IR-cut filter removed) on Astrotech AT66ED

Nice pic. I couldn't take nice pic with DSLR. want to try again.

Lol mines far from nice but with your incredible mobile station I'm sure you can!

do you take darks? How do you match CMOS dark Temp with Exposure?

Yeah, I usually take Darks, Bias and Flats, at least 1/2 the number of Lights, 100% if time allows, so 20 Light Frames I'd try to get between 10 - 20 Darks, Bias and Flats.

Stack them all in DSS, tweak a little of the RGB, Luminosity and Saturation, just a little.

Rest of it is done in Photoshop with Layers, Curves, Levels, Blurs etc.

Anyway, going through the Lights for my Eta Carinae, realised a few of them actually had very thin high clouds passing over them, so removed, restacked and re-processed.

Personally, I think this is a better result than the one above:

yes nice. why not you add about an hr exposures, it will create decent image of it. I am waiting for testing RGB Imaging tonight but sky still not yet opened.

Yeah, I know I should lol. But these days due to work and part-time studies, I'm shooting from my flat and Eta is actually only available for 30 mins in between 2 HDB blocks.

Maybe I'll continue to take a few when I can then do a 3rd compilation after I gather more frames.

Btw, I showed my missus your pics and she kept going "Wahhhh! why he can take those u cannot?".......




LOL

When a single 30-sec frame gives you this much details, you know you're in for a good night!
