| Quote (Martek) Great shot. How do you get photos to look like that without star trails?
It's just next to the celestial pole, and i used a bright lens, so it could be done without trails.
Quote I understand this is 13 photos stacked at 25 sec exposure each right? Which stack program is this? I have used Rot N Stack, do you recommend a better one?
I use Deep Sky Stacker, usually with dark frames but not this time. It's then processed in photoshop.
Quote (HarbingerDawn) By using a tracking mount
Usually i do, but i moved to a different country and i don't have my mount here. I might get a ioptron skytracker sometime.

| Various old shots (90's). This landscape looks a bit alien at night:
Moonlight is bad for star gazing, but I makes better landscapes:

| My first semi-serious attempt at photographing the Milky Way:
Canon Rebel T3, 15s exposure at F/4.5, ISO 1600. Might need to bump up the ISO and exposure a little bit, but not a bad start. I just wish the center of the galaxy wasn't masked by Seattle's light pollution. :/

At least you see it and it corresponds pretty well with what you see with the naked eye? But f/4.5 is not good. You have a zoom lens, I suppose. Consider getting a fixed focal length lens which is much faster? I.e. f/1.4 (or if you have a excess money f/1,2).
I shot the photo below with 800ISO film, 16" using an 80mm f/1,4 lens (Nikon). Milky way centre and from Mauna Kea, but the brightness still surprised me. At f/1,4 I had pretty bad vignetting, though.
A better sky definitely helps...

| Yeah, I only have 18-55mm and 55-250mm zoom lenses available, so until my next little splurge I just have to make do. 
Here's one that's a little better. I went a full 30s at ISO 3200, so there's minor star trailing, but I figured that was better than doubling the ISO again to 6400. At this point it's a lot better than what the eye can see from here. If I get a chance I'd like to drive out to a darker site east of the mountains and try photographing Sagittarius and the central region, but from this latitude it is fairly low to the horizon. Your shot from Hawaii is really impressive!

| Your exposures seem similar to one Milky Way shot that I've taken from Oslo:
Unfortunately, I can't find the metadata.

It's still much more than I can see  I wish I had skies like many of you guys seem to.

| Skies like these?

Last night was clear enough to catch some Perseids:
Nothing spectacular (all of them lasted less than a second), but not too bad considering that the radiant is the opposite way and that the sun only reaches 14 degrees negative altitude so the night is still short.

| Here's the new nova!
August 9 (pre-nova)
August 16, 09:25 UTC
It was visible to unaided eyes after a few minutes of dark adaptation, and presently appears to be between 4th and 5th magnitude. So evidently it is still brightening!

| It's also featured in today's APOD. If it gets brighter than 3.9, it will be the brightest in 14 years. It needs to get above 2.6 to become the brightest in 38 years.

A bit redundant, eh?  Nice shots Watsisname.

| Thanks guys. I'd always hoped to someday photograph a nova or supernova. Having photographed the exact same region of the sky a few days beforehand is some crazy cosmic coincidence.
Quote (HarbingerDawn) bit redundant, eh? :p
Heh, I suppose it is.

I too photographed that same region of sky just before the nova occurred, on Aug 11/12 and 12/13, but I haven't processed all of the pictures yet. When I finish I'll post pictures and a video link to the timelapse. Next chance I get I'll do another timelapse with the nova in it

| Keep posting pictures, Harb & Wats.
The nova seems to have peaked at ~4.3 and then stabilised slightly brighter than 5.
