I'm so confused

Hey everyone,

I got a 6" dob the other day and attached my 600D to it. I'm running Linux so having some problems with .mov to .avi conversion and stacking in registax that way. I did however uninstall Linux and install Windows back on my laptop and got BackyardEOS (Haven't gotten the key yet).

Anyway, can someone look at these two images. The top one is the one Registax spat out at me after I stacked 80 odd images I took and the bottom is just one of those single images. I see no different, I haven't gotten any decent processing software yet (They are all so bad so far) but from what I can do I see no difference.

Thanks for any help.

I did take this one of the moon that did make a decent difference: http://imgur.com/qUMxrTp

What were you trying to image?
All I see is a white dot?

OK - Why didn't you have at least one Barlow lens to increase the image scale?

I suggest you go to the Solar system section & ask there?

It's not an area that I specialize in.

Thanks mate I'll give that a look.
Can you get a barlow that will work with a 30mm Canon SLR T-mount?

Again - ask in the solar system area.

You can get get a 2" power-mate that your T2 connector for the camera will fit into. Teleview have a 2x and I think a 4x version.

From memory the 600d is full frame so you it will be hard to get a decent scale for planetary imaging. You would need a scope with upwards of f15 to get anything that doesn't resemble a small dot. I'm assuming your dob is about f5 if so you would want a camera with a cropped sensor to help gain a larger scale. DSLR dont make very good planetary imagers unfortunately. Your moon image looks really good.

I've been imaging for a number of years now and I've never done any planetary imaging because it takes totally different equipment than deep space photography. I'll get around to it one day.

The Canon 600D is an APS-c sized chip. WhiteRabbit is thinking of the Nikon D600, which as 24MP full-frame chip.

A quick Google search tells me that there are 2" 2.5x barlows and 5x 1.25" barlows available.

Without having tracking mount you may have a tricky time getting a large image scale and avoiding motion blur - let alone actually keep Jupiter in the frame.

Good luck though,
Cam

Registax spat you out because your image scale was way too large and Jupiter was nothing more than a point. It doesn't like trying to stack point sources like stars.

Does your dob have at least the ability to track? If not, then your only target is going to be the moon. As some have already said, bump up the image scale to get a decent sized planet pic and you're going to find it very difficult to keep the planet you're trying to image in your FoV. You need a mount that can track in alt-az at the very least, to be able to get reasonable planet pics. I wouldn't bother using a DSLR for anything other than DSO's and the Moon. To get decent planet pics you're better off getting a modded webcam at the very least. Even better if you get a dedicated imager for planet work like a Flea, DBK or even a good astrovideo camera like a Mallincam or GStar. Then, to get decent image scale, you'll have to boost the FL of your dob with a barlow at the very least. Better yet, invest in a Powermate.

That'll get you started.

you can set your video settings to 3x digital zoom. its similar to the older video crop mode.
