Just had this problem for the first time after fitting self made dew shields. Any idea what weights to attach to the backside??

Revised edition of M81/82 NGC3077:

Got M81/82 and NGC3077 (6hrs 40min - 300s at ISO800)

I love the focuser too - holds the Canon 450D proper like. The supplied 2" EP is a beast! Amazing... But it doesn't come with a lens cover - only a bottom cover.

Argh - my mistake!!!! Please ignore me!!!

And a single M52 60s shot:

Got another one. Full moon with a Canon 450D. 50 frames stacked at ISO400. Didn't use darks/flats/bias...

+1 SW 0.9 coma corrector

How big was the difference between the full spectrum modded Canon and the Atik 383L? This is the one I've been thinking about. Or the QHY8... (but it's not mono...).

All images have been made with a Canon450D (unmodded), on a HEQ5 PRO goto, 9x50 finder guider (QHY5). Me and my garden gnome: several M51 crops: M97 & 108: M81 & M82 (& NGC3077): M81 & M82 pre-SN: few M74 crops: dragon fly cluster: and M33 crops:

Hi guys, having fallen in love with my 130pds, and seeing that I'm not the only one recently, I was thinking it would be nice if we posted our images made with a 130pds here. It gives a nice reference point as well, as to what could be achievable (with better guiding, better camera, better weather...). Well, here goes:

The idea in GIMP is, after processing everything in Registax - make a new pic first, totally black (helps), then open as layer your jupiter picture (this u can derotate and flip according to your gusto, I do a bit of brightness/contrast/sharpness back and forth), then open as layer your moon picture (that one will need sharpening, contrasting etc.). Now you have a big bright blotch in that picture, right? Don't worry about it - take a note of it's position [unsure how to align to pics] because u will need to move the proper jupiter pic in the right position. Now open the layer dialogue window (I couldn't find it for ages - it's under windows/dockable dialogues/layers). Right click on the moon layer and click on "add layer mask" - a little box opens - choose "black full transparency". Now you see the jupiter picture, choose "brush" from the tools menu (make sure that the layer mask is high lighted - the little black box behind the moon thumb in the layer dialogue window) and start "painting on this jupiter picture in the area, where the moons are supposed to be - and voila, they magically appear. Then you need to apply the layer mask (right click on it) and flatten the image and save. Finished.
