Thank you very much for your answer, Watsisname!

Also, the paradox that you mention in the end is very intriguing.

Could it be possible that they are bowling balls rather than cannonballs perhaps?

Hahahahaha yes it is. Let's just assume that the portals are wide enough (and that they are all perfectly align, of course).

Science and Astronomy Questions

Yesterday I had a thought experiment, and I would like to share it and ask about it. Let's assume that we are in a place next to a random planet, and in that point the gravitational acceleration is 1 m/s 2 (just to make calculations easier). In that place, Dr. Stephen Strange created two portals: th...

Qr Bbpost pzampella, awesome screenshot! i like it with or without the disk! 

Hahaha thank you Spacer! But I really want to pull out that disk, otherwise that picture can't be titled "Andromeda's Galaxy", but "Andromeda's Galaxy Core with noise".

Is there any Pixinsight expert around? I'm having some trouble processing a picture of M31 and maybe someone can set me in the right direction. I stacked several M31's pictures and process it with Pixinght. Tha main problem is that I can't get the blueish dust disk at all! I even get that dark cloud...

8890 looks like a telescope hubble ones! Nah! The first thing I did after seeing the result was checking the professional ones and the difference is quite noticeable. But I still can't believe that I managed to pull those up! 8892 Great images! 8897 Quite impressive Thank you! It's good to know tha...

So, I finally had the opportunity to go away from Madrid's light pollution into Alicante, and managed to get this pictures. I processed all three with PixInsight, and I can't believe how different they are from those with all that city light. I hope you like them too: http://forum.spaceengine.org/do...

6978 I'd wish I could make something like that! Mosfet , is not that hard! I was just following  midtskogen idea of background removal. To achieve that using PixInsight I just had to create a mask to protect brightest stars and galaxies, and then I streched the image with the Histogram Transformati...

Well, after 4 hours of multiple sessions with different expositions (51x30s, 39x90s, 62x90s and 20x240s, each one at ISO800), this is the final result:

I don't think it's possible to make any more improvement without a better and darker sky. Any thoughts?

6251 did you edit a tiff or jpg file, also whats the original resolution of this image? I stacked RAW files into a TIFF file, and that TIFF file was the one that I processed. 6339 I've found it's better to push exposure times longer (as long as star streaks aren't apparent) and keep the ISO to 400-...

Watsisname ,  I like that idea. So as soon as I get more lights to stack I'll try it, because right now I'm enjoying my 45 days trial of PixInsight, but after that I will have to go back to Photoshop. Using DSS I stacked the lights from last night and the ones from the night before that (all of the...

First, thank you very much for your advices! 6180 as for anyone i can always recommend stacking,for your images i would take atleast 30-50 lightframes and 30-50 darkframes with iso 1600 or 800 and 15 to 25 sec exposure. Sorry that I didn't say this in the original post, but those images are both aft...

I have a couple of questions and maybe somebody can help me. I live in Madrid and there is a lot of light pollution, however, I have the Astronomik CLS filter. I understand that that's not ideal, but it's all I got. I've been using it with my camera on my SkyWatcher BlackDimond 150/750 telescope wit...
