 I guess I need to look at one in person. I have an old meade lxd75 that I could not get good tracking out of that I had intended to be portable mount. But at time I was using an 8" Newtonian that acted like a sail in the lightest breeze. I may dig it out and see how it behaves with a lens. I would love to have something easier to haul on trips.

Looks like it tracked pretty well. What tripod did you use it on?

This was 12x50 sec at iso1600 with my 7d2 and 300mm f2.8 II lens at f4.  No calibration.  Stacked in DSS and then stretched with pixinsight.

 I like  how you have processed it. What settings did you stack with ? Median should get rid of those satellite tracks .

You are doing a fantastic job doing it that way. At some point you hit a wall where noise swamps the signal and only longer exposures will help, Jrista could help you better. Maybe build yourself a barn door tracker . You already have good data on the brighter stuff, I would give it a try and add it to what you have.

Still a work in progress, really having a ruff time with this one. The tail is clear to me in the subs but getting it pulled out of the star field is really pushing MY limits. At least I had another hour of clear skies before the clouds moved in last night  :)  This is with the 5DIII and 200 2.8l II, so it spans about 7.5 deg. here. I have some other processing steps to try and tons of subs, so maybe eventually.

TLau74 , careful this can lead to sleepless nights. :D Looks a lot better than my first attempts at Orion, quite good for 1.6 sec. I think it is actually one of the harder objects due to its wide brightness range and the super bright core. Are you tracking? To get the fainter parts you need to expose the background if you can't see the background you can't see the stuff that is barely brighter than it( if that makes since?). Think of the last two screen adjustment bars on one of those gray scale screen adjustment bars and setting your screen up to see the difference in them . ETR works even better at night .

Great images, guys! I'm glad to see some of you are getting into astrophotography. :) It's a great hobby, especially if your an insomniac like me. :P


nightclicks, excellent results with M42 there. You managed to pull out some of the faint outer dust, which is really quite a challenge. You must have some decently dark skies to do that.

Once I get out of the glow of Tulsa it's not to bad as long as the humidity doesn't swell the light dome.I can visually make out the milky way , but only because I know it's there ! Last Thrusday was probably the single best night in a year. Actually it was perfect, light to no wind, low humidity, excellent seeing and 40's to start. unfortunately I got sick before I got the longer subs for the faint stuff, and of coarse clouds have moved back in since. I think if I reprocess I can improve it some ( I have forgotten most of what little I used to know) , full size it is a bit over cooked the really faint stuff is really blotchy looking.

Thanks, Click. I forgot to mention I took these with the SL1 as kind of a test. Those using one of the Vixen or similar trackers may find it a suitable option to shave some weight. I got mine during their refurbished sale last month and I like it so far, a few annoyances but usable.

Here is comet Lovejoy from last weekend.  I'm still learning pixinsight and that is much more daunting than actually taking the subs.

Working on some new subs I took last night.  Good split in the tail.  My biggest issues are finding any clear instructions on the finer settings within the tool.  Experimentation seems to be the best way to learn.

Looking good. I hear you on the experimenting, I am still trying to figure out how to best process what I have on the comet.  I did manage to get some short subs For M42, but had to shut down before I had time to get any longer subs for the faint stuff. First clear night in months ( and I mean perfect ) and I have to get hit with a stomach bug ! Anyway, this is 133 x 14 sec taken on the 16th,a little over processed but at least I have something to work on.

Here is one with the 14 cropped to 24mm, hope it helps

Here is a 30 sec upper rt corner with the 14@ 2.8 on a 5DIII . This was due west @ 35 deg lat, so a little elongation but no coma, it's a very nice lens for the money.

Very nice. I am always amazed at the clarity of you images. I find it hard enough to get any clear nights with light pollution I can't imagine needing 2 or 3 times as many without . Orion is in the perfect location for me right now, but we only have had one clear night in the last month and that was Christmas eve.

I would think they would add all the cameras ,64bit systems will eventually be the only choice. At least the cameras that currently work with Windows 7.

Post Processing / Re: DNG vs. original RAW in the long term

How do you plan to archive the photos, whichever format you select?  Just curious.

That's a good question.I have seen more media broken by firmware, drm , drivers, etc that made It only readable on the device it was original made on, especially cd's and DVD's. That's why when I build a system I make sure the dvd recorder is compatible with the most file types but that is no guarantee of future compatibility.
