Originally posted by ToddK Excellent shots and description of what you did/had to do to pull it off. I have no experience with Milky Way shots, so your experience helps me. Plus I am familiar with the overlook and it is encouraging that the Forest Service was willing to work with you. Thanks for sharing it!

Originally posted by Just1MoreDave I read the previous posts about getting permission without realizing that I've been there. It is a great drive. Excellent shots! It's not so terrible to have to plan another visit to try again.
Thanks for the encouragement. I've been touching up the images and trying different things - post processing and things have gotten a tad better. That and I have found that if I re post process the prior set of images just prior to going out again, I do get better images. Something like a little positive feedback loop, so when you are out in the field shooting, you are making somewhat better decisions on the fly.
Yesterday (Monday) afternoon long about 2 to 2.30, I pulled up one of the many Sedona webcams and clear skies, clear radar, so
Road Trip. Everything was pretty much ready to go (yea, right! more on this as you read). I actually found 2 additional batteries that I thought that I had lost up in Alaska, so I charged them on Sunday and I'm back up to having more than plenty of power in any event. I hit the road by 4.30 with a full tank of gas and rush hour traffic is not toooooo bad. Pick up a bite to eat on the way (Camp Verde is always a good location for a quick pit stop). I decide on the way to take a slightly different route - going up canyon, so as to get in possibly 2 locations in - as I am feeling really very confident this evening. I stop at West Fork that I shot this time last year, getting there at 7.30 and I'm early! Total darkness is at 8.00, and things are going pretty good.
The Milky Way is not in the V of the canyon yet, so I scout for some good foreground interest, and sort of settle for about the best I can do in the meadow. There are some good sized trees that I didn't remember being there last year, but - whatever. I was sort of hoping for a better view of some of the canyon rock faces - but you shoot what is there, and not worry about it. Set up, calibrate astro, mount the camera on the pano head sitting on the geared head mounted on the tripod, so I can just shoot a fixed 20 degree vertical slices with LOTS of overlap. I adjust the moon lander articulating screen (I really like the articulating screen a lot). I plug in my external shutter release (I remembered it this time around), but the 2 second delay is still on - no big deal, push the shutter button ...... and then the little center AF [spot box] pops up in liveview and the lens starts auto focusing - *$#@^& and I instantly know that I no longer have focus, even with the focus ring taped down. So, I spend the better part of the next hour trying to manually focus both at 15mm and 30mm - no joy. So, I bagged it and head home empty handed. Just shoot me! The idiot behind the camera didn't check out the basic camera setup. Another lesson relearned the hard way once again. Famous last words.
So, in a few minutes, I'm gonna go drive over to this little cul de sac on the side of a nearby hill a couple of miles away and re pre focus the lens on a set of hills about 10 miles away. Put the body in MANUAL while taping down the focus ring again, so I'll be all set for next time - perhaps tomorrow afternoon - again. I am running out of no moon days this moon phase (the rest of the week) and there is a high pressure system over Sedona all week, so clear skies and no clouds.
So, what was hoping to accomplish with this outing?
- On Saturday night, I shot at 60, 90 and 120 second astrotracked exposures. I had shot previously at 50 seconds and was VERY happy (no star trailing in the corners at 15mm). I didn't want to press my luck so I was sort of staying at 50 seconds for the most part of this year. This time, I decided that since 60 seconds was good and that there was just the ever so slightest trailing at 90 seconds, with some minor trailing at 120 seconds, I would go for 70 seconds. That would be 40% more star light captured. I've been looking at the take from star trackers at 2 to 5 minutes and yes, there is a lot more light and brightness as well as color, but to me it appears to be unnaturally bright. I want something a bit more natural, and I think that 70 seconds will do it. Even with my slightly out of focus shots at 70 seconds, for me this is going to be the new standard.
- Fort he K1, ISO800 has been outstanding. I've been toying around with perhaps going with 400 due to the headlights, but - I do think that 800 is better. On Saturday night - everyone was shooting the canyon (think road car rally), there was substantially less traffic on Monday evening, so I think that traffic volume was the main problem I was seeing on Saturday. The problem is that you need to have enough definition of the dark areas, and shooting the landscape segments at 2 minutes at 800 is probably better than 400 at 4 minutes - and then there is LENR which will double all the times. You need to balance out the exposure time with LENR against the brightness. Bringing my external shutter release (with a timer / intervalometer) - provides this. Plus, you can check the image and if there is a burn-in, just retake it. LENR even though it doubles the exposure time is worth it for the K1 - it eliminates the white dots (my only real complaint about the K1).
- The canyon activity, down in the canyon, showed up nicely on Saturday, but on Monday there was substantially less (fewer campers), but there were still the canyon resorts, cabins, retreats - so I'm thinking that 2 minute exposures should do nicely - for the landscape images for the foreground. I did a couple 30 second exposures for stacking, and they were not too bad, so again 2 minutes feels like a good number.
- Of all the landscape shots I took, I didn't take nearly enough on Saturday. I actually thought about this while I was there and though that I was find. When in doubt, take more. I was going 5 images wide. I should have gone at least 6 to have more material to really get a good handle when post processing, how wide is sufficient. In looking at the images I did take with the headlights, they were substantially better with some post processing and VERY usable. I'm really sorry I decided to not take the images that appeared to be really blown out. They would have turned out better than what I was thinking.
- Also, while I was there, I was thinking about putting the tripod legs (at least one or two) up on the rock wall. Yup, I should have done that. That I think would have provided just a bit more freedom in terms of formatting the shots.
- Shooting two sets of images - one at 15mm and the other at 30mm, turns out to be a real advantage. There is a real difference in detail with the 30mm image set. The 15mm set is essentially the quick look set, that shows the potential or lack of potential in the 30mm set. Also, the processing time is minimal.
- Four years ago, I had decided to stay with the K5, and not go with the K1 when it eventually came out whenever. So, I saved up for the Sigma 18-35/f1.8 lens, which for astro works great. I had tried it out a year ago on the k1, but with stitching it appeared to patch work things in with a lot of vignetting (on the K1 at 35mm). I'm thinking that it was oversampling errors using Microsoft ICE, so I want to try it again. The f1.8 is a good stop and a third faster than f2.8, and I could stop down to f2 and still gain a full stop (plus another 40% with 70 second exposures). Since I already have the lens, there is no reason not to try it out and see what results it produces, especially with stitching. It would also be interesting to see the astro color rendering in comparison to the Pentax coatings on the 15-30.
- Photoshop - Even though my wife - the Chancellor of the Exchequer tells me it's updating everything I have on the list is not in the budget, Photoshop CC - I hate subscriptions, and Adobe in general, but it will help everything immensely. I think that she will go for PS.
I'm thinking of trying again tomorrow night again....
