Antza2, Splendid..!
I took the liberty to stitch the pictures together and enhance the brightness/contrast of the image, 50% reduced. It is just a quick and dirty processing. Have you ever considering stacking some shorter exposures ? I think you can achieve greater results.

Yeah, but i'm not sure how to do that. :/

I have multiple photos of that same area, so i could try it out. smile

I'm no stacking expert at all, but I'd suggest the "DeepSkyStacker" software, there is plenty tutorials around to help you. You also would need calibration frames, some are pretty easy to take, others need a bit more set up. Depending on your computer power and number of frames to stack, reducing or cropping the original images may be a good idea.

I think I never shared those first and only planetary & nebula astrophoto I took last year through my window with a 900mm telescope, less than 10km from Paris, so light pollution is huge.. Stacking of 85 images for orion :

Very nice images you two! Love that eclipse sequence.

Antza2, another very good tutorial for 'the theory' of image calibration and processing can be found here (also linked through the DeepSkyStacker FAQ). I like this one as it keeps the explanation fairly simple, showing why we do each of these steps as well as examples of the effect they have on the image with different numbers of frames.

It seems like a daunting procedure at first, but it's actually pretty easy once you get the hang of it. And not all of the steps are required -- even just stacking the light frames will improve the signal to noise. But the more of the calibration you do and especially the more frames you take, the bigger the improvement will be. I think it's definitely worth trying out. smile This is what just 8 light frames and 8 dark frames can do... no bias frames, no flats.

A rare spell of beautiful weather in southern Norway now ("rare" meaning completely cloudless sky, which is rare here). I just spent three days hiking, which will be repeated next weekend. Autumn, which is often just neither summer nor winter, can be nice.

midtskogen, that neat, its like the pressure in the dead sea area (-400 meters). about 1.05 earth atmospheres (x1.05 sea level)
i am very interested in weather too and i watch maps every day. can you explain what high pressure zones means with weather?
for what i remember low pressure zones over israel (less than 1000 hpa) came with lot of snow and cold air.

saw that image too:
