To @Andy Resnick and others:
Andy, I've stumbled upon two links I'd like to share:
Focus stacking (with Photoshop):
Photoshop Playbook: How to Blend Multiple Images with Different Depths of Field (youtube)
Noise reduction stacking
(a method with Photoshop and some other software, I doubt it's better than DeepSkyStacker, but anyway):
A Look at Reducing Noise in Photographs Using Median Blending
We have very cloudy skies over here at the moment, and no noise reduction method will fix that... I am waiting for clear skies...

I figure this thread has room for one more awesome shot of a familiar planet.
wonderful photo of red sprites
I have yet to photo these, still on my bucket list
I have a stormchaser friend that photo's them quite often .... here's an example .....
I agree, those things are amazing to look at. I wonder, without video, would anyone ever get lucky enough to photo them? seems like even on "burst" setting a still camera shot would be extremely long odds of recording them. I notice there seems to be many more Sprite images out there than the Blue Jets, are the Sprites more common ?.
I devoted an entire thread to that image about 6 years ago. I think I looked at it too closely.
Of course, that was before Marcus got me hooked on Ceres, so some of the things I said appear to be incorrect.
It is a composite, just not what I would have called "composite" back then.
An actual photo from Saturn's rings, taken by Cassini (only cleaned to remove cosmic rays and detector noise). Source
Ring Nebula (M57): first image is full frame (800/5.6), 1h 46m exposure, second is a 1:1 crop.
Lots of objects are in view now (for me): Jupiter, Saturn and Pluto are all favorably positioned and Cygnus is coming into view. One more clear night to see if I can capture Pluto....
yeah, all the time as with that photo I posted above
the usual way is just to do a string of timed exposures, as Marko did
I guess this is Earth more hunred years because trash of people in the Earth
Back from vacation, busy doing class prep. It was cloudy every night, so I ended up making timelapse 'videos', here's two of them: one frame was acquired every minute, starting around 6pm and going until I passed out around 2am
A good one, managed to hold a constant exposure during an illumination change of 24 stops:
The best one- see the (near) full moonrise, a thunderstorm, lots of activity.
Very nice, @Andy Resnick!
5 hours of viewing (400/2.8 ISO 640) over the past 2 weeks:
Stunning, @Andy Resnick!
A few images of the starfield in Cygnus: the first one is about 3 fields of view at 400mm (full frame) covering most of the North American nebula and the second is the veil nebula, nearly filling a single field of view (at 400mm). The density of stars is really striking.
very cool images mate, well done
A cool shot of Jupiter on NASA's image of the day.
Great ISS flyover this evening:
Cassini's picture of Saturn with the Sun behind Saturn
Predicted view from the moon Titan.
Meanwhile, no satellite, no flyby, no animation, no photos, no video, no NASA tech crew - nothing but birding binoculars and naked eye; but as a total beginner I was pleased to get my own first-time view of Saturn last night, a very bright dot just below and to the left of the equally bright waxing crescent moon. The dot really did seem gold in color; I thought this might be my imagination until I looked it up.
Nice what setup did you use
