imaging planets

[cardconvict]

Hi all, does anyone no of any good guides on the internet for imaging planets. i do normally just do dso but jupiter is now approaching us, well my neighbours hedge is in the way. but would like to dip my hand in this;)

You have QHY5v which can be used almost like DMK21. To get color with mono QHY you would need RGB filters (and IR passing Pro Planet 742 for better IR-RGB images) and a filter wheel.

thanks riklaunim my qhy5v is a one shot colour

Then it's easier to start. When I was playing with 5v I used Nebulosity2 to capture FITS files for each channel (it was mono), but you can also use free QGVideo32 to capture AVIs.

You can start at f/10 (no barlow/reducer) and capture frames for up to 2 minutes, then stack it (Registax for FITS, Castrator/Autostakker or Registax for AVIs) and play with processing like wavelets or convolution. You can always hit the forums with raw stacs and some results.

To get bigger scale a barlow would be needed. GSO/TS/Revelation 2x/1.5x or similar Antares are handy as you can unscrew the lens and screw it into the camera nosepiece and get 1.5x "extra"

ok thanks, is there alot of difference between qhy5v and dmk 21? also is there any bad reason for having a one shot colour.

After processing results were nearly the same = very good. As for color cameras - it's hard to use some filters with them. For planets IR luminescence is commonly used to make the image better (IR-RGB) if the seeing isn't very good. With color matrix only 25% pixels are sensitive to red and IR so it's harder to record the IR luminescence.

thankyou for the advice and do you know of any good sites that i can go to

Only one I have bookmarked at the moment, hope it helps a little;

Webcam Astrophotography Tutorial for Planets

I don't know any tutorial site. You can watch castrator + autostakkert tutorial on my site but that is just stacking AVIs part.

thats fine just bits and bobs to start me off thanks
