Re: Cat's Eye Nebula

Hi Ron, that looks really good. Due to the high dynamic range it's a pretty tough target as far as I know. I haven't dared trying it, also because of the fact that the core is so bright it gives diffraction spikes with a Newt... I am bit surprised that HDR didn't have an impact on the core. Did you ...

Re: M63 - interrupted by - Aurora Borealis

Hi Dietmar, sorry for my late answer! :oops: Thanks for pointing out the purple cast. It's not particularly strong and as you said, many M 63 images look similar. But it's been my impression there could be a bit more differentiation of colors. How did you get your NGC 3718 so bright? Well, part of t...

Re: M63 - interrupted by - Aurora Borealis

You just have to love that galaxy. Amazing details, Dietmar :thumbsup: . And a well tamed core! Did you use HDR? I have the impression that the galaxy has a slight purple color cast overall. In my experience the core is yellowish and the spiral arms have some blue in them. Maybe the channel alignmen...

Re: ngc3718

Well done :thumbsup: Looks effortless which means quite something with such a difficult target. I like the faint stuff of the galaxy, the details in its companion and the rotation of the galaxy. :bow-yellow:

Re: NGC 3718

With the opportunity of some clear nights I revisited NGC 3178, a warped spiral galaxy with its companion NGC 3729 and the Hickson compact group #56. Really cool target but not so easy. Hoped to get more faint stuff around NGC 3718 but with some thin clouds still being around that hasn't been in the...

Re: m65

Hi Steve, very well done :bow-yellow: Stars look great, overall processed with decent style. And do I see the stellar stream of the Hamburger Galaxy? I guess the image contains quite some integration time. And that the full res version looks pretty impressive. May I ask what your settings for color/...

Re: NGC 4151 and NGC 4145

Thanks, Freddy! And yes, I also heared the noise of rain hitting the window quite often lately. But the cloud cover since January is even more annoying. Let's hope for the best.

Re: M94 an in-progress fool's errand (and an experiment)

Great image, Ron. I know it's not an easy target (https://www.astrobin.com/m47syf/) and I love the amount of detail in the core and the dust lanes you got. I tried to shoot with 5 min subs but overexposed the core. So I ended up with shooting 1 min subs for the core and layering both images (as is c...

NGC 4151 and NGC 4145

Weather and life reduced the amount of time I was able to spend on AP (and commenting on some of the great images posted here...sorry). But recently I was able to image a star field with two galaxies (and some fainties) over two nights. https://cdn.astrobin.com/thumbs/aYoxPY8Rtq3c_16536x0_ieTZ0INm.j...

Re: Mosaic processing

I haven't done a lot of mosaics either, but I already encountered the problem with the monochrome outcome when processing a M31 mosaic (https://forum.startools.org/viewtopic.php?f=11&t=2329). The reason was that I opened via the 'open' option with the data source being OSC. This results in a monochr...
