The link below describes a supposedly "new" process for capturing sharp ground based images; by selecting the sharpest and stacking maybe? I'm wondering if this is a more sophisticated version of what we've been doing here for some time?

I took a look and it is quite interesting to know, that's the exact thing(keeping distances...) we've been doing here!! The only difference is that(and there is some info detail left as to the duration of the frames' capture, and their camera frame rate...)they capture for long lapses and I guess Planets are not included in these captures... From what I understand from reading, these high quality results were only achieved with "close binary stars, stellar clusters, as well as rapidly varying sources like eclipsing binary stars or rapidly rotating neutron stars known as pulsars". (no planets are mentioned, possibly because of relative fast rotation of some of them...) Anyway it's great to know we follow very good methods to get the best planetary detail and they resemble to more sophisticated methods used by serious researchers...especially by those imagers here whose cameras get 60fps or 100fps. Hey Jim, I was wondering where you'd been!! Hope to see your images of Saturn very soon (it'll be seen at dawn very soon so get ready!!) Hugs and thanks for the link!!

Imaging deep-sky objects like this requires a large mirror to overcome the faintness of the objects, but then you have the advantage that they aren't changing, so you can spread your observation and capture out over long time periods to find enough good frames. cheers, Bird -------------------- Deep Sky Optics 13.1" f/5.5 newtonian, PGR Dragonfly Express, PGR Dragonfly 2 RedHat Linux + Coriander http://www.acquerra.com.au/astro/ Post Extras:       gazerjim Postmaster Reged: 02/12/04 Posts: 7774 Loc: About where I thought I was......

I'm sort of laying low, working nights and eagerly awaiting the return of Saturn. Good seeing, Jim -------------------- Jim Fisher If you're not part of the solution, you're part of the precipitate.

[Re: gazerjim]       #1109627 - 08/23/06 09:02 AM Edit   Reply   Quote Quick Reply   Thanks for the info Jim. I went to the website of the camera manufacturer and it's most affordable camera is a 658X498 CCD with 10um pixel size at $9k!! It is capable on only 30fps at full resolution. I think I'd be better off with a Dragonfly Express!! Regards, Chris -------------------- Post Extras:       gazerjim Postmaster Reged: 02/12/04 Posts: 7774 Loc: About where I thought I was......

Sounds like they are working with the benefit of big bucks. Jim -------------------- Jim Fisher If you're not part of the solution, you're part of the precipitate. Henry J.

[Re: gazerjim]       #1110500 - 08/23/06 06:58 PM Edit   Reply   Quote Quick Reply   Seems like they are aiming at deep sky targets, so their camera specs make some sense - they're not wanting large magnification so 10u pixels are ok, and probably 30fps is more than enough for faint targets unless you have a really large mirror. cheers, Bird -------------------- Deep Sky Optics 13.1" f/5.5 newtonian, PGR Dragonfly Express, PGR Dragonfly 2 RedHat Linux + Coriander http://www.acquerra.com.au/astro/ Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 2 registered and 7 anonymous users are browsing this forum.
