Getting DSLR magnification for planets?

[johnnychaos]

I'm using a Canon 300D directly connected to my Skywatcher 150p dob. I've taken a few images of Jupiter, but they are tiny and I'm not seeing anywhere near as much detail as I can see with my eye through a 10mm eyepiece.

I did see in a skywatching book I got years a go you can get camera adapters were you can slot eyepieces in them, but can't seem to see any online.

I have got a 2x barlow which has made things a little closer, but wondered if there was anything else I can do?

not really, the sensor size is way too big for image scale on the planets. If you want to image them, then you really want a webcam, something like..

Johnny I have the exact adapter you are referring to. It's called an eyepiece projection adapter. see link below. I actually bought this one from ScopesnSkies.

Antares 1.25" combined T-mount camera adaptor and eyepiece projection unit

I have only used it a couple of times on the moon and sun and I have to say the webcam solution (which I also have) as suggested by John gives better results so far. But I have not really given the projection thing a good run yet.

I have the 400D and you will suffer the same problem as me in trying to focus accurately without liveview - it's not easy is it. I find the eyepiece projection makes focussing even on the moon more difficult than prime focussing with the camera mounted direct on the telescope.

Can I ask a dumb question - where does the barlow fit into things if you are coupling the camera direct? I cant see any way of introducing the barlow in my set up. Maybe I missed something though

Chris, If you are able to attached the camera to an ep (I've got a Hyperion and t thread adapter for it) then you can barlow the eyepiece... It's hard enough without doing that mind you...

Actually Johnny I may have thought that last bit through myself. I have to take the eyepiece holder out of the way and screw the t-ring direct on to the scope. If I leave the eyepiece holder in place and have an eyepiece adapter attached to the t-ring I don't have enough inward travel to bring the camera to focus. If I was using the eyepiece adapter I would obviously be able to slot it into a barlow lens.

I'm still interested in how you are connecting things - I could learn something from you .

Thanks John, I am now going through the multitude of bits and pieces in my accessort case to see if there is any other options! I'm sure some of these things I don't use have a purpose!

So presumably for DSO the technique is the same and you have to buy one of those four figure CCD camera to get any kind of magnification?

The Sky-Watcher 2x barlows that come with the Explorer scopes have a T-thread at the top. I tried a few moon shots with the barlow and a 300D and it was pretty hopeless.

Nooo. Most DSOs are bigger (apparent size) than the almost point-like planets. My M42 has been taken with the EOS directly attached to the scope. If you do the same, you should get (almost) the same size.

Oh gotcha :iamwithstupid:As you can see I have only just started anything DSO related.
