Ok this not with a canon, but my new CCD QHY9 camera.

But been posting for sometime here and thought would share it.

Here is my second ever image with this camera since I got it last week, learning like crazy with the new stuff.

Worked out FITS, Headers, how to stack in DSS, convert to FITS, convert to channels, re-merge to LRGB etc etc etc and the list goes on.

It is fun, lots of fun.

Well here is an attempt on M81 and M82 Bodes in full moon light for LRGB, so definately not the best conditions. No LP filters were used on 5 min subs for LRGB, so the QHY 2inch filters are really good and calibrated well to remove the LP

LRGB (140:40:40:40) on QHY9 with QHY 2inch filters

Imaged on Skywatcher ED120 Pro Diamond Black Refractor 900mm, F7.5

Guided with EQ6Pro, ED80, QHY5, PHD

Processed with MaximDL, DSS and CS3

Managed to get flats and bias sorted, but couldn't get MaximDL to take them properly without errors, so single processed the LRGB in DSS and re-combined them after messing with the FITS headers etc.

Not brilliant, but was under 90% moonlight the other night, but all learning process in the short nights before the winter.

Well enough of the excuses, here is my 2nd ever CCD shot. I added the diffraction spikes because I liked them and they seemed to frame the picture nicely.

IMAGE NOT FOUND
Byte size: ZERO | Content warning: NOT AN IMAGE


I must say that the rumours of the QHY9 are old rumours of the 1st run of CCD camera's. I have seen the posts, but these have been sorted, the camera is awesome, large format and cheap.

Very nice shot.

Those two galaxies are one of my favorite telescope fields, but visually even through a large instrument you don't see near the detail that you have captured here.

Wow Cat! Never seen that much color in Bode's Nebula before. Guess the LRGB is the way to go. Question...did you use a filter wheel and take images in the different colors or just extract the color channels and process them individually and recombine? Either way you got great detail!

Individual LRGB frames with filter wheel, processed individually and combined and re-processed mate. Took about 1.5 hours.

Very nice detail. The brighter stars though have a bit of a red halo and M81 is especially teal looking, it's usually more blue than green.

Wasn't sure about the colour as hard to find good amatuer pics of this object in good colour.

The halo's are hurting me at the moment, not sure what is causing them.

Awesome. How much exposure time? Just curious....

Great capture Cat. Looks to me like the red frame is slightly defocussed compared to the others. Did the temperature change a lot during the sequence? Are you sure everything is well aligned in the imaging train. Problems like this are the main reason I went back to one shot colour.

wow your eyes are good. I have noticed that my focusing is slightly off after my recent M13 work. It seems focusing on a BIG vega with a mask is not accurate enough. I know focus on smaller stars to get the accuracy.

The LRGB filters seem to be parfocal and accurate.
