Can webcam imaging be done with a dob?

[johnkirkpatrick]

Could I do planetary imaging with my set up?

I have never attempted it before but might give it a shot.

[Merlin66]

Yes.

Registax will bring the images back into alignment then stack for best quality.

You may have to keep repositioning the scope between videos.

[johnkirkpatrick]

Thanks I'll give it a go.

with planets you should increase the f ration to say f20 or f30 using barlows so a f5 newt should be good with a 3 or 4x barlow, but for the price of the webcams and a couple of other bits it`s allways worth a go i`m sure you will get good results

I have had a go at a couple of months ago when I first received my Morgans webcams and billetparts.co.uk nosepiece.

These are the best that I could achieve with my setup, I found that movement in both axes was very sticky and caused the image to fly all over the place. Maybe getting some ebony star or an equivalent laminate applied to the AZ axis and teflon tape around the ALT bearings would help in this respect.

I gave it a go with my f4.7 10" dob. At F4.7 I got about 10 seconds before the planet is out of view. But then at F4.7 the image is too small. I tried with a 2x barlow and begun to get problems with keeping it in the f.o.v. and the time available before the planet drifts out of view is lessened accordingly. I can only imagine that at F20 or F30 it would be very difficult. Maybe ultra wide angle eyepieces could help.

Maybe it would be possible with a tracking goto type dob?

[ollypenrice]

You do see images done this way but I haven't ever tried it.

I'd trust Ken on this.

The answer must be in the affirmative, but it certainly isn't easy! A tracking Dob would obviously help, but extremely difficult without?

Take an AVI while the planet crosses the field of view.

Stop imaging just before the planet reaches the other side.

Then process in Registax.

The short time while the planet is in the field of view will reduce the total number of images it has to stack, but it certainly works.

[johnkirkpatrick]

Thanks for the help, I will defo give it a bash, there's a lot I don't understand ie AVI and stacks bla bla bla but once I have the equipment I'm sure I will get it lol.

I would be happy with your pic hypernova If I manage to get that I would be happy.
