Hello everybody,

Finally I had some luck with Jupiter, quite happy with these pics so I thought I'd share... they're a bit grainy but compared to what I had before I'm stoked.

All pics were taken with the DMK21au618 through RGB filters and the Baader Mood & Skyglow with IR cut filter.

Can someone explain to me why the pics taken with the Celestron 2x Barlow have a bigger (more magnified) Jupiter then the one taken with the TV 2.5X powermate???
I would have thought it would be the other way around.

Gee, I'd be stoked as well

These are great images.

Cheers
Jo

Great effort.
RE the difference btw Barlow and Powermate, this link explains their lens construction, which may explain their apparent magnifications

Thanks for the feed back and link Jo and Bo.

Jo I still havent monoed my 300D, but I found a 300D sensor replacememnt so when I start scratching away at the sensor and happen to destroy it, I'll have a replacememnt. The Links you sent helped me to prep a lot, so thank you.

It's a lucky fluke Dunk.

Pretty awesome nonetheless

Great result!

Re the 2.5x and 2x issue, I read on these forums a while back that you can change the apparent size on the chip by moving the camera closer and further away from the Barlow lens - i.e. don't necessarily slide it all the way in if you want a bigger image. After all, using a Barlow is a type of eyepiece projection, not prime focus.

Maybe this has something to do with it? Maybe your camera is getting closer to the powermate lenses?
