Here was a start on NGC 6960. It has 40 minutes of Ha in it. Im not happy with my framing so ill rotate the imager to get more of it in the FOV. It was...
Hi everyone, I've finally gotten some time to try my hand at this narrowband thing and set my sights on a nice big, bright target last night, M27. I'm using an...
That's a good puzzle, Dave. Definitely looks like a scaling problem. CCDStack or Registar can deal with scaling easily. If there is skewing as well, only...
Dave, are you using a matched set of filters? Mixing filter brands could possibly lead to this depending on how fast your system is. Jim Livermore CA...
Hey Neil, I would like to figure out why there is a scaling difference between these filters. They are from the same manufacturer and are nearly parfocal. They...
Could be that they are not totally flat in the mounting. This is a tough one, Dave. ... www.flemingastrophotography.com Direct from Boston - brilliant...
I have been kind of sitting on this data for a while now, mostly because I haven't had time to finish processing, but also I could add to add to it. I had the...
Nick, I really liked the detail and and final result with the sG layer. Paul ... because I haven't had time to finish processing, but also I could add to add...
I've been working on this one for awhile now. I was surprised at the band of S2 across the bottom lower left of SH2-112 that seems to float in front of the...
Thanks Paul, I appreciate your nice comments. I have found that from my light polluted location using a green filter brings out the worst of gradients, and...
Very nice image Paul. I have found that the additional exposure times make the background detail stand out much more. Is the background mostly Ha or SII, or a...
Nick, The background is mostly Ha with some S2 in the area close to SH2- 112. I attempted to leave this in the picture to bring out and highlight some of the...
Very nice, Paul! Personal taste, but here are a couple of possibilities for you: 1) Select the stars, and use a selective color or saturation adjustment layer...
Good approach and result on the color combines, Nick. Ha for Red is fine, and I've noticed that the sG approach does well in approximating the 'real' colors. ...
Hi all, I know this is a bit off topic, but I've seen references to photoshop, AIP4WIN, CCDWare's family and other products on this group. As I move toward...
Thanks Neil, I noticed that using this approach, stars are influenced more by the great Ha signal as opposed to blue. Ideally, and RGB adjustment layer for...
Hi Dave, For me, Photoshop is an integral part of my image processing toolbox. I use Maxim for capture, CCDstack for pre-processing (calibrate, align, DDP) and...
There are indeed many tools used for initial processing, pre-Photoshop. Once the initial processing is done, all roads indeed lead to Photoshop. (At least in...

I was able to capture some images of the Tulip Nebula again. This time I tried to get some SII and some Hb. Seems that I was not successful. I shot 10minute...
I'd recommend 30 minutes, Rob. That's one of the drawbacks of narrowband...you really have to bang on the object data collection hard. Looking at my data, I...
When using SII and OIII do you typically run your subs at 30minutes? I seem to get decent results with Ha at 10minutes, but am strugling to figure out where to...
Hey there, Rob. I go 30 minutes for each of the three filters. OIII and SII really should be an hour, but that would be taxing even for my patience <g>. ... ...
I went up to some 20 minute shots on the crescent last night. It seems that I still have an issue with my focuser collimation. Stars just dont come out round. ...
Which scope and focuser, Rob? ... www.flemingastrophotography.com Direct from Boston - brilliant diamonds in pea soup Also check out the astro_narrowband Yahoo...
I am using the orion 8" reflector and a moonlight crayford. I am going back through the entire system today. I just centered up the focuser which I think is...
