Ron, Nice detail in your M1 image. I believe an increase in saturation of about 40% would bring out the color of the Ha filaments in the nebula as well as...
Nicolas is right. The FSQ/6303 combination is 3.51 arc seconds per pixel. Sure makes up for ~2-3 arc second seeing. If everything is done well, near ...

Thanks, Neil, Dan, Leonard and those who commented. Your suggestions helped greatly. Dan - the ellipsoid appears to be real. It is in the OIII, Ha, SII light...
Thank you Neil and Nicolas! Neil, one question: "As the night goes on, the focus position moves inward, not outward..." Why is this, something to do with...
... Yep. Even in my Bostonian crap, that is what I have found <g>. ... I know there is very much a legitimate debate as to the degree to which a narrower...
... Yepper! ... Do you mean tricolor? Or do I misunderstand?: http://www.flemingastrophotography.com/ic1805.html ... I appreciate your sense of exploration...
... You're most welcome! ... Nope. I believe, although I could well be wrong, that the lens optics somehow 'shorten' up with the lower temps. Given that the...
Hi Don, Thanks for checking out the image, I tinkered with the color on M1 quite a bit but I think I will rework it over the weekend. I will post the results...
Friends: If I wish to image emission nebulae during a full Moon with a modified DSLR, I understand that a narrowband Ha filter is necessary. Can I image other...
Neil, A picture just before process, a composite from ccdstack but before processing on photoshop. I would like to see ! you could put it on your FTP. I just...
The Olll wavelength is quite close to the wavelength of maximum power from the sun. However reflected light is often polarised, has anyone tried using a...
OK All, This is a bit off-topic but just found out the good news that the Dall-Kirkham C20 design that Celestron was going to produced when it was bought by...
Very interesting thought, John. I have not tried that. I wonder if there exists a filter without the darkening function usually associated with such. ... ...
SII works fine, but OIII will suffer from gradients. At least that is my experience. ... www.flemingastrophotography.com Direct from Boston - brilliant...
Hi Neil I'm afraid not, the reason they are dark is because they are only passing that portion of the randomly polarised light which is vibrating in that ...
On the advice of Jon Talbot I used the Selective Color tool in PS to reduce the Magenta halos around the stars in the SII-Ha-OIII Orion image. Here's a link...
TOTALLY open to interpretation, in my opinion. Some folks have almost a religious passion for leaving them as is. I, like you, tend to prefer to remove the ...
Hi everyone this is just an FYI for you who may be interested. Registration for the 2007 NorthEast Astro-Imaging Conference is now open! For your registration...
One of the nice things about renting telescope time over the internet is finding clear dark skies somewhere in the world when the weather is awful locally. I...
Hey John :) A very nice image especially with such a small amount of data. I have not seen a star for 3 weeks here in Ohio. Good job !! It's a lot of fun...
Thanks, Jeff. Glad you liked my image. NGC3372 is really bright, and I figured I could get all three filter data sets in one session with the f4.7 Sky 90 and...
Hello All, I think this is my first post of an image I decided to take an image of an object I've always been interest in imaging, the Christmas Tree/Cone...
Hi All, I have been having a lot of fun with my H-alpha filter. It is giving me 30 minute subs fairly close to the moon and with a lot of ground light. Can the...
First post? A heck of a lot better than my first! <g> You're well on your way! ... www.flemingastrophotography.com Direct from Boston - brilliant diamonds in...
Neil, "Ground light" for me is my neighbors and the good old 100 watt bare light bulb. H alpha does not seem to mind the "ground light" as much as my RGB...
I finished a high resolution closeup of NGC3372 this morning, only to realize after the fact that the camera had been moved with the instrument rotator between...
