I know this isn't quite as good as some of the others posted on here, but after several days of effort, I'm glad to at least have a recognizable image.
Meade 2120 (10" SCT)
40 Lights - 45" @ 1600 ISO 40 Darks
80 Dark Flats
Stacked in DSS, but since the objects were so dim I could only get one light frame to stack. Used Curves and Levels in Photoshop to bring out the object. I live in a bortle 7 zone, this was shot from my backyard. Moon was about 50% last night, so quite a bit of light pollution. My SCT has such a simply tracking system that it is impossible to correct- hence the short subs. My polar alignment has to be PERFECT to get any kind of lengthy exposure at this magnification. I tried 90" subs but there were noticeable trails.
very, i would think it would be career suicide to do what he's done.
The dude hijacked Taylor Swift’s Grammy at the height of her popularity and was practically universally hated by everyone after that... for a while. He’s surprisingly resilient.
Shot with Nikon D5100 on the Skywatcher 8" PDS and an Skywatcher EQ6-R.
Integration time: 257x30" (best of 370) - total 2.2h
Processing done in PixInsight.
Rough processing outline as far as I remember it:
Great work I took a shot of m51 last night and it looks nothing like yours. I could only get one frame to stack in DSS so I lost a lot of detail. I took only around 40 45” subs though. I was getting eaten alive by Mosquitos and had to pack it in.
...I’d be curious if you could pull anything better out of my data with your process...
my original plan was to photograph NGC 4631 but it became so windy that I decided to switch to an easier target. So I ended up taking pictures of M51, one of my favorite targets.
Here is an older image with the same scope but without guiding and with a different camera: http://goedhartvoordieren.nl/?page=r/astrophotography/comments/6e3f6o/m51_whirlpool_galaxy/
Great shot! No flats? How much light pollution?
I normally don't do flats because I have to crop the corners of my image anyway due to coma. That solves the vignetting problem automatically because I shoot without reducer. There is still a good amount of coma visible in this image so maybe I didn't crop it enough this time.
Heres a 2x downsized, stretched, calibrated image in case you are interested: https://imgur.com/a/KQgHK
The light pollution was minimal. I always drive to a remote location without street lamps or alike.
Great! I’ll be shooting M51 in a week weather permitting... but I have a fair amount of light pollution where I live, and my SCT uses an old quartz drive so the tracking isn’t perfect enough for 90” subs, I’ll see what I can do!
Wait, is that a brag? I thought that was the average size in North America.
Edit: This isn't some kind of r/ihavesex, I've had friends who were made fun of for 5 inch dicks and because of that thought the average was 6-7.
It’s large for a 12 year old, which I assume is OP’s age.
Stephen King absolutely cannot write an ending to his books. I love his characters, I love his descriptions, he does a magnificent job with atmosphere... but dear God, the man could not write a satisfactory ending if his life depended on it.
Dumb question- but what is that grippy-looking tape thing covering the m-lock openings across the handguard? I’m assuming it’s to make it grippy, but I’ve never seen it before.
The physics still don’t add up. Think of the weight of 22k miles of fishing line. If it’s more than the weight the line is rated to- it’ll snap. The strongest fishing line in the world is rated as 15 times stronger than steel- pound-for-pound, but would still disintegrate over the distance you’re talking about. That much length of fishing line would weigh between 200k-300k pounds.
Acting like the majority or entirety of people in a group are the worst people in the group is the definition of stereotyping.
Political humor, what happened to you? You used to have really good Trump/republican party jokes (joke implies there's a punchline) and now you're just "Haha, Trump and Republicans are dumb!"
Pretending like every republican is a fat white redneck who hates every minority group isn't funny, it just seems hateful. Make fun of actual hypocrisy and bad logic in the republican party--there's plenty--not this straw-man version of a republican.
Edit: Just to clarify, I believe in liberal ideals, but I also believe in good comedy. It's not the fact that this sub makes fun of Trump, it's the fact that they don't do it in a funny way that I have an issue with. It should be actual humor in this humor sub instead of just shitting on some straw-man image of a republican.
Thank you for posting this. Both sides do this a lot and it drives me crazy.
Sure, I don't have your personal experience...
Why are you so angry? All your comments seem super negative. I’m not trying to incite anything, I’m just genuinely curious what is going on.
