Christmas Comet Linear (C2003 K4)

[seeker372011 (Narayan)]

Here's some information I picked up from another forum:

first some links:

http://www.shortcourses.com/choosing/sensors/05.htm

http://astrosurf.com/buil/d70v10d/eval.htm

and here is what some people had to say


quote:

while the Nikon D70 may take a slightly sharper pic. The EOS 300D gives a smoother image at ISO100, less noise. Also the D70 applies post image processing that may be detrimental for deep sky imaging in addition to dark frame subtraction

BTW the guy who made this comment had pictures published in Sky and Space-last issue

and

quote:
net result looks like the D70 is more sensitive but gets bogged down in its internal processing, so one has to look at the trade-offs and accept the fact that the Canon is best-net-result-wise.

Thanks for that Seeker372011

There you go Paul, you really wanted the Canon anyway, this just makes it easier.
Let us all know how it works, when you get it.

Hey Paul, if you want some more in-depth reviews on the D70 or 300D, or any other digital camera for that matter, then go to dpreview
The fact that you already have a canon with a good range of lenses, it seems your choice may have already been made. Happy hunting!

Thanks for the link Silvie, I'll check it out.

When I get one and if I ever get a clear night without a big moon, I'll let you know how it goes Gary.

Thanks all

Paul

Paul,
the DPReview site is good, but really is slanted fair and square at the digital camera enthusiest that doesn't use their gear on the night sky. Still a good look area though.
Don't be put off by the moon, I was, until I tried the Linear shot, and also the M42 trial the other night.
OK so no moon is better than full, but.......................

Sorry Paul, I was in a rush posting this morning so I couldn't mention that the dpreview site was geared towards daytime digital photographers. So thanks for pointing it out Gary. It is still a good site nonetheless with a features search that you can use to find digital cameras that would be suitable for astrophotography. For example, you could do a search to see with cameras have a bulb setting, or exposures longer than 30 seconds, something that is useful for night photography.

[gbeal]

Silvie,
yes, and yes it is a very good site. I hadn't considered the search function you mention, so it will be useful for Paul, but I reckon the 300D is already a done deal.
Now you need to get one.

Bad news Gary and Silvie.

I'd thought long and hard about it, (all of about 4 hours) and decided to go ahead and get the Ted's Camera House deal (300D for $1400 with a 256 meg card and carry bag thrown in) tomorrow,Thursday. Unfortunately my car had other ideas.

On my way up to the observatory tonight "something" started to make grinding noises in the front end whenever I turned towards the left. By the time I drove home it was only not making grinding noises when I turned towards the right. And being a 4WD its not going to be cheap even if its only wheel bearings. There goes part of my money for the camera

Well I guess the camera can only get cheaper

[gbeal]

Oh No, oh well, as you say they can only get cheaper.
I hope your headache isn't too expensive.
Gary

Good news.

Its *only* going to cost about $200 to get the wheel bearing fixed so in celebration I drove to Brisbane and bought myself a celebratory present. Yep you guess it. A canon 300D. WooHoo!

So all I need to to now is learn how to use it. Oh and a few more nights without clouds and moon

And happy new year everyone

Paul

Hey well done.
Using it is easy.Get the appropriate T ring and slip it onto the rear of the scope, perhaps with a focal reducer first.
Use shortish exposures at about ISO800 or 1000. Try some at 30 seconds, and some at 1 minute. You will need about 6 - 10 of them, and stack them in Registax.
Practice makes perfect.

Way ahead of you there Gary

Already have the "T" ring from my EOS500 and I made sure I got all the basic astro gear when I bought the LX, Wedge, Reducer, Off Axis, "T" adapter, variable tele-extender. Just gotta cut down a few trees to make the most of them

Now for some serious fun. If I can get away after next Tuesday (when my bearing are being done) I'll get to give the Canon a real workout.

Thanks for your input and have a happy new year

Paul

Congrats on your camera Paul ! BTW is your 4WD a pajero , if it is i can understand the wheel bearing problem !

[[1ponders] (Paul)]

No its a Suzuki Aragorn. Genuine bearing $250. Non-genuine $75. Guess which way I'm going
