Managed to get 18x5 min subs of NGC3372 on Thursday night before bed time. I'm quite pleased with how it turned out.

The Jpeg is heavily compressed to get it under the posting limit but there's a full res version here:

Thanks for looking - comments/tips welcome.

Hi Peter,

Some nice sharp detail in that eta image, your stars, look great almost pin point!

Cheers,

Justin.

Looks good Peter, the larger image really show how sharp the stars are.

Well done

Excellent image of a well photographed nebula. Good to see the mmpc is working so well with the camera.

Nice sharp photo but the colours seem too red to me.

Nice Peter. That seems a pretty wide FOV for the 10" though? :question:
I'm probably just out of practice...!

Colours look nice to me, there are red and blue stars to be seen - which is always the acid test to me, what the star colours are like.

I've seen Alpal comment on this before - I think your unmodded camera is just insensitive to H-alpha, which is fine if you're going for the "what it looks like to the eye". Ours eyes aren't very good detectors of what these objects are actually emitting though.


Cheers,
Cam.

Thanks Justin. I'm pretty happy with the MPCC.



Cheers Geoff. It's been a long time between images with the weather and gear issues so nice to get a good result for a change.



Thanks Allan. Think I've got the spacing pretty close now.



Thanks Apal - I've not messed with the colour balance - that's how it comes off the camera. My DSLR makes EtaC look a lot bluer however I assume that is the Canon UV/IR filter cutting out the Ha. The QHY8 obviously passes a lot more Ha.



That's it Rob - 63x42 arcmins with the MPCC.



Thanks Sue :rofl:

It would have to be something in Scorpius I imagine!

Stars look a little out of focus to me they look like little circles when zoomed in, and you have a little coma in the corners, other than that looks good.

Thanks for the comments Peter. I think the focus was ok looking at one of the unstacked frames. Perhaps the circles are a stacking artifact?

Lovely, mate. As others have commented, nice tight stars. Not a whole lot of blue in the Ha emission nebulae, is there? Colours look pretty close to me.

you are an artist that knows his tools - very nice Peter.

Peter


Yes same with me - a lot bluer with a stock DSLR.
You're just picking up all that red Ha with a CCD camera.
