This is an image I took at the Texas Star Party 2009. I used the AstroTrac tracker and my Canon 5D Mark II DSLR with a 24mm Lens at ISO 1000. Because the...
Great image, nice to be able to still pick out the constellation stars amongst the milky way background - was that a single 10 minute shot? I've been trying to...
Hey Dean, I'm confused about the details of your awesome image of our galaxy including its center bulge. You say that the earth had rotation during the 10-min...
... Hey, I remember that sky! It was worth staying up for -- stunning. Great shot Dean. I thought I had the only AstroTrac on the upper field (never saw...
I just have read the group_rules.txt in the 'File' directory which has been posted two days ago. The first paragraph may be the answer why no official comments...
Hi Perry I understood that since the earth had rotated end that it has been compensated by the AT so the lanscape is blurry. So he took a uncompensated 2-min...
Hello All, The Leo Triplet M65, M66 with NGC 3628. An interacting system 35 Mlyrs away. NGC 3593 can be seen top right of the frame. Image here > LEO Triplet ...
Gain Really nice Leo triplet – the 400mm lens (Canon?) seem to work pretty well. I like the framing with the triplet to the right and the details in the ...
Thanks and to the the comments from others as well. The lens is not the best (Canon 24-105 F/ - 5.6 zoom L lens) But I stopped down to 5.6 at 24mm. I have a...
Hi Gain Your excellent Leo triplet shot was of great interest to me as about a month ago I did something similar with my 500mm lens and a series of three...
It would have been nice to hear they are fixing that issue and or many of the other issues,,rather than just mail them with your complaints.The newer model was...
Hey Matt, Thanks for your comment and you are correct...tracking was ok but the field near the edge had slight coma. The stars nearer the centre are much...
Hello Andy, Thanks for the compliment. The triplet is such an interesting grouping of interacting galaxies lying between us and the virgo cluster. It is in the...
Hey Gain, Thanks for that very nice image. I've been wondering how one frames the trio and gets NGC 3638 in the FOV and have enough magnification to give...
Thanks Perry, Yes, the frame was cropped which suggests more detail can be had by using a slightly longer lens and still keeping all four galaxies. regards ...
... Indeed! Funnily enough I've just been given a link on one of my other forums to a tutorial on processing (see http://www.istarion.net/Processing.htm ). I...
Andy, One word of caution. In my example on those pages I push the black point a little to close to the begining of the histogram mountain. There is a risk of...
Hello Perry,,looks like all have gone to sleep here,,was wondering how the wedge for the Voyager you made up is working out,,I know when you swing to Polaris...
