First shots with my DSLR

[04Stefan07 (Stefan)]

Just did a few first shots with my DSLR before it got cloudy. Here is what I used:
- Canon 350D
- Timer remote
- T-ring adapter
- T-Adapter
- 2x Barlow lens

Some settings (still learning):
- Tried ISO 200 and 800
- bulb
- Aperture was on 00 (I tried changing it by what the manual said but it didn't change, anyone know why?)

The pictures came out a bit blurry (could be my tripod doing it cause its wobbly). I wanted to get a shot of the moon like I would see through a 15mm-20mm eyepiece, the 2x Barlow was a bit too close.

I know I need an adapter but no idea which one, anyone can tell me which one?

Still learning with a DSLR, so far it's been OK just a bit frustrating when you take about 40 shots and only 6 look ok lol.

I have attached the image.

Thanks

Hi Stefan,


To me it looks like you just needed to adjust the focus. But its still a good shot.
Settings like ISO 100 & 200 and a fast shutter like 1/400 or around that speed are good.

Cheers.

Yes, because you weren't connected up to a camera lens, you were at prime focus of the telescope (Nexstar 130, right?), so you can't change aperture.



My advice; if you're shooting the moon, ISO 100 or 200 and if shooting jpgs, use daytime/sunny day white balance.
To get focus right (using 350D no live view), slew over to a medium bright star and focus that through viewfinder, then don't touch focuser again, should be very close to focus.

Just practice and play around with different shutter speeds.

Congrats on your first piccie. You've got the contrast just right.
That's good advice you've been given.

[04Stefan07 (Stefan)]

Yep I will try all those things that were mentioned and see how I go.

I used my Barlow for the shots, what do I need for a wide shot of the moon?

Thanks for the advice

I went out again and still similar results.

What is the bulb setting? Is it better for shutter speed to be on bulb or as was said below 1/400?

I think the bulb setting is my problem

[jjjnettie (Jeanette)]

The Bulb setting is for when you are doing long exposures , using a remote timer.
For Moon shots, try ISO200 and 1/250th sec. But experiment as was mentioned before.
To attach your camera to the scope, you will need a T Ring to suit an EOS camera.

You may need to purchase the nose piece to suit as well, if your adaptor in your focuser isn't threaded to suit.

Stefan,

Have a read of this manual by Greg Walton (MPAS) . It is an extremely good tutorial on DSLR AP for a beginner, tons of info, hints and helpful advice.

The PDf file is quite large - 18mg and takes a little time to download. Link is about half way down page.

With a 77mm f/6.3 SCT camera lens I get reasonable exposure on a half moon with 1/125sec and ISO100. I would expect with a 130mm f/5 Newt and a 2x Barlow, those settings would be a good place to start. 1/250sec is a bit dark but does seem to stack OK.

Thank you!

After the first batch of images I took 2 nights ago, I just processed them through registax (followed a tutorial) and photoshopped them. This is my first proper attempt, what do you think?

The image was originally a bit blurry so I couldn't do much about it.

I also rotated it 90 degrees cause it looked better haha.
