Fingers crossed

 Nice picture i am new at imaging and am learning that the gap between the initial subs and the final image has so many variables that it becomes an art in itself.

I have to agree with you there. I'm rapidly learning that the acquisition of the data is the easy bit. it's the processing where the fun (I think it's fun) begins.

I've been at it now for about a year which sounds a bit but when you think this adds up to about half a dozen descent nights..... well I tend to forget more than I learn between sessions .

Just for reference, here is a single untouched sub from the stack.

[Alien 13]

This is my 1 min sub like i said bad LP

[DaveS]

Ouch! That looks worse than mine, but probably mine would look like that without the CLS filter.

Not sure if the Hutech would be better with my variety of LP, but funds are too thin ATM to try it.

Correction, I *do* have funds, (From mum's estate) enough for one of those lovely 7" APOs if I were totally barking, but it's ring fenced for building work. Afterwards I'll see if there's anything left......

[Scott]

I now  use a cls clip filter and really like it. I think M31 is trickier than you think (I've certainly had no great success on it) A friend of mine put over 25 hrs into it with a dslr which took him 18 mths. It certainly was/is a stunning image but I'm not sure I've got the patience for that.

As a side note, he too lives in/nr London so it can be done.

[DaveS]

One thing I might have funds for is getting my 550D modded, which would, at least, give me more at the red end. Though that would really tell on H alpha nebulae.

[Alien 13]

I realy need a LP filter but i am happy with my results so far from a washed out sub to this.

[DaveS]

Yep, that pretty good considering what you're starting with.

I think your colours are better than mine, due to the CLS filter.

If someone had said a few months ago that it was possible to even get an image of a star let alone a galaxy i would have laughed all i want to do is get the best i can from my garden view and i love the challenge. 

[DaveS]

I dunno, but that Hutech filter's looking more and more attractive.

I. Must. Not. Spend, Anything. More.

[Hawkeye]

Well here is my first lot of processing 

M45 14*300 seconds lights + 10 dark frames + 10 Bias frames, Stacked in DSS and then tried to tweek it all is PS

SW200P on HEQ5 and Canon 1000D

Oh and you WILL spend £600 on a mount!

[Hawkeye]

And also 28 * 30 seconds on M42

Again stacked in DSS and a small amount of playing in PS (I really need to learn the processing part)

[Alien 13]

Nice image thats my next target.

I suppose it depends on your LP.

Here I am in a yellow/orange area on the LP map but I have my obsy set up so my view

is from NW thru East to SE. This way I lose most of the LP from the town.

Only snag is I get the light domes from Horsham, Crawley/Gatwick to the NE.

East is ok but just behind me to the West are football club floodlights and a school that

has floodlights on till real late.

Here are two subs without any processing, first one is 30secs at iso 3200, second is iso 6400

To give an idea of the LP,  here is an unfiltered 600D 55mm....20secs at iso6400, taken around midnight.

[DaveS]

Now here's a thing.

When I was looking at these images last night I was using my main computer with a Dell wide-gamut monitor and was seeing all kinds of dodgy colour artefacts, but on my laptop with its rather feeble screen the images looked fine.

So (If anyone's still following this thread) what monitor do you use, and do you see colour banding etc?

[Hawkeye]

I have been using either my laptop or tablet and they look OK except for my rubbish processing

Don't see any colour banding on my Compaq lappie.

Can you give us a screen shot?

Have a look at this video on Youtube. It has some good tips on how to bring out detail in an RGB image created from RAW files. Easier than reading a book/manual!

That's funny, I was watching that very video on Youtube last night and playing with my data again...

I still didn't get much out of the data but there again I was only taking 30 seconds subs so not really expecting much.

Looking at my images (and data) again I don't think I was quite in focus which isn't helping me much.
