toucam vsersus LPI versus digital cameras

Posted By Greg Bradley
Hi,

I am new to astrophotography and have an LX 90 and an LPI.

So far I have been unimpressed with the LPI.

I also have a Canon EOS 35mm camera a Sony DSC 71 digital and a sony digital camcorder.

I like th eimages seen with the Phillips Toucam.
Is this the best all-round choice for astro work? That is wothout spending $10,000 on an SBig plus extras.I don't think I'd want to take it that far but I would like to take some nice Jupiter shots, some shots of M42, Omega Centauri, 47 Tucanae and Milky Way broad views like Maurice has posted.

Advice?

Cheers,

Greg.

Beginner 35mm first attempt

Posted By Greg Bradley
Hi,

I have an LX90 telescope and a Canon EOS 10S 35mm camera with a 35 to 105mm zoom lens.I planned on pulling the zoom back all the way to 35mm.

I have seen some great 35mm shots of the Milky Way (I live in Australia).

I am going to a dark site next week and thought I'd piggy back my 35mm to a dovetail bar I have on the LX90.

So with maximum F 3.5 stop on the camera and Kodak 400 speed film, what sort of exposure time should I go for? About 20 minutes?


thanks,
Greg.

beginners advice

Posted By Greg Bradley
I am looking to gear up for astrophotography. I have a Canon EOS 10S 35mm camera, a Sony DSC 71 digital and a Sony digital camcorder with a nightswitch function.Also a Meade LPI with a Meade LX90 scope and a Tak FS 102 soon.

Is there a general consensus about gear? I have been following the posts for a while and it would seem a ToUcam is great for Planets (unmodified or modified?) but not so sure if there is a medium cost all round CCD for planets and deep sky.

There is the Sac 7 and 8 and the Atik series of modified ToUcams.

Any suggestions about what gear to get? A ToUcam and a Sac 7 or Atik?

A camera adapter to use the 35mm on eyepiece projection?I have a large range of Naglers, Panoptics and Plossls.Be nice to put them to work.

Thanks,

Greg.

Nikon D 70 camera for astro photography

Posted By Greg Bradley
Hi,

I just bought a Nikon D 70 and a Scoptronix adapter for use in astro work and have an LX 90 and a Tak FS 102.

Has anyone had any experience with this camera and can advise on what they found to be the best setup in terms of exposures and software to process the images.

I have taken some early shots of the moon and jupiter and the Jewel Box.
I used about 1/50th second exposure on the moon using a 19mm Pan eyepiece in the Scoptronix adapter and that turned out quite well. I used the timer to take the shot so there wouldn't be any camera shake. Jupiter required about 1/5th of a second (ISO 650). Deep sky is hard to see in the viewfinder of the camera to get an accurate focus. I think I will need to get it parfocal during the day so I know where focus is or focus on the moon and keep that lined up as the eyepieces put in the telescope once the camera is removed need quite a bit of focus adjustment.

Also a remote for the bulb setting shots is probably essential as holding the button down for exposures is not practical and 30 seconds is the max the exposure will do automatically.

Cheers,

Greg.

Say, that's not a Glob, THIS is a Glob!

Posted By Greg Bradley
Omega Centauri.All 10 million stars of it! What a sight in the Southern Hemisphere! The jewel of the night sky.
So how many coming over to Aussie to look at it?

Considered to be the core of a former dwarf galaxy that the Milky way has absorbed. By far the largest glob in the Milky Way.

Vixen R200SS F4.0, Sphinx mount with Version 24 firmware, drift aligned, Nikon D70, 7 x 30, 3 x approx 60 secs. ISO 1600, Images Plus, Nikon Capture Editor V4.1.

Clear Skies,

Greg.
