M31 59x180s ISO 160

[Daniel]

Hi All, I managed to get almost 3 hours on M31 last night, im using ISO 160 for most of my imaging now and Im finding im able to control the colours much better at this ISO.

Im quite chuffed with this one, spent extra long collimating and focusing to get it bang on.

Seeing wasn't great last night, and tranparency was so-so (couldn't see all stars in Cassiopeia) but seem to have got some decent data, would love to give this a go on a still / transparent night and try 240s subs.

Imaging details are as follows :-

Imaging Scope = C14 with Hyperstar III
Camera = Canon 40D (Modded)
Ambient Temperature = 5 Degrees Celcius
Filters Used = CLS
Date and Time Taken = 17/10/09     12:30am - 2:30am
Light Frames = 59x180s ISO 160
Dark Frames = 16x180s ISO 160
Flat frames = 100x1/13s ISO 160
Bias  = 100x1/8000s ISO

Anyway, enough info, here it is

That's very good Daniel.  Your collimation certainly looks spot on and you've got plenty of detail and contrast (better contrast than my version of M31).

You also have some nice areas of H-alpha which mine lacks - probably because you are using the CLS filter.  But I think the CLS filter has also caused that greeny hue.  I have seen the same effect when using the CLS filter to image galaxies from my own back garden.

To get that quality of image from where you are located is incredible.  Well done!

Please do, as it allows others who are just starting to see how you achieved your image.

ps, keep up the good work.

[Daniel]

Thanks guy's, I've re-done the colour to get rid of that green cast, what do you guys think?



Daniel

[Mike]

Now it has a reddish cast to me.

Great image Daniel,

I am not as advanced as some on this forum (in imaging, that is, before Ian says anything), but this is my favorite object to image.
I still prefer the 1st image to the 2nd, as this now seems to be more red.
Still great detail.

Ah damn, will have to try to find a middle ground between the 2, I like having a nice orangey core, but I don't want too much of that spilling into the outer limbs.

Daniel

[Carole]

Yes, 2nd one looks too pink to me too.

Yes please, for people like me, especially as you have a DSLR and this is the route I am now going down.

Thanks

Extremely nice Daniel!!!!!

[Daniel]

Eugh, just seen the second image on my laptop at home and its horrible, waaaaay too pink, last time I trust the monitors at work!

Daniel,  have a look at the colour gradients on each channel as I think they may be different, that will hamper getting the colour balance right.
