Shot this at Ten Chain Hill on Friday Night. Got about 8 hours data but started shooting when it was only 20 degrees above the horizon so a couple of hours worth don't really count. As the image was originally gray, I used artistic licence on the colours
Almost every thing is shot binned X2 as it's so dim. First one is sigma stacked and 2nd one is summed and cropped as it was full of gamma bursts and satellites
I am impressed. That is a hard galaxy to do and you've got it very well.
In a way, I find your image annoying in that I have imaged it as well
a few months ago with gear that cost 10 times more than that and mine is
no better - grrrr.
These GSO RCs really are incredible bang for your buck.
Another fine example of the GSO RC capabilities. I prefer the uncropped version and the blue is just a little green in that image. Use of the green extraction filter will provide an awsome image. Lovely work overall and really impressive galaxy shot.
Time to sell that expensive gear Greg and get onto the GSO bandwagon mate. The 12 is looking good so far.

Cheers Greg, but still not even close to Martin's image. I couldn't go longer than 10min subs due to flex but I do have an orion OAG on order so that will solve the flex issues and then I can try and get a new deep Lum layer for it.

I've been thinking about getting the little RC6 for a "grab n go" imaging scope. If it performs half as good as it's big brothers, I'll be happy
I could push it a bit harder but it starts to get noisey. More data would be best. Don't know of anyone here with the RC6, I think a few people on CN own one.

Yes, thank you nettie I'm enjoying a bit of FL. And you stop using that Tamron lens, your making me want to spend money I don't have

Well done.
It wasn't looking too good yesterday when I combined them Doug. But a bit of Lum stetching and sharpening brings it up a bit. Not too bad for x2 binning I guess, a lot better than the one I took at astrofest with the tak last year.

That 2nd one is sum stacked paul, the thing is really dim and summed definitely gave me more data, but it was full of artifacts and noise I have run the hasta lavista green fixer over it and have replaced the original image, it does look better, thanks.
Robin with faint stuff I have been using median on the RGB which is binned 2x2 the my lum which is 1x1 I am generally doing summed with long deep subs. 20 minutes or so is the best bet on dim objects. It might not suit each persons setup though because of mount issues or light pollution. However, I find for my location I can go quite deep without causing any real issues.
Paul, 10 minutes is about my limit on my RC8 setup before I start getting streaky stars due to flex. I'm prone to aircraft at home so sigma combined fixes that. The attached image is usable with sigma
The OAG I ordered will fix the flex but apparently deliveries from Japan are very much delayed at the moment. Been waiting over a month now and I've been told a couple more weeks waiting
Way to go Robin - the binned subs have definitely pulled out the fainter arms like you hoped. As Greg and others have said, that really is a top shot for such a faint beastie. Marathon effort too staying up that late
My only quibble is the colour of the arms. Might be worth trying to get the colour balance right before the non-linear stretches.

The beauty really of median combine is it reduces noise. It fades out the satellite trails, gets rid of the cosmic ray hits etc. Sum does not. Its accumulative whereas median is averaging. So one image with a high number in one spot not on the others caused by noise gets reduced with every extra image taken. Some people like sum. It probably gives absolute maximum resolution but only if your subs are pretty clean or you use the healing tool more to clean up artifacts at the end.
Very nice, Robin! I got a bit of data at Ten Chain too last night, but nothing quite so ambitious.
Good to see you got everything going Rick. It was pretty cold and wet by 3am Saturday, I didn't sleep at all, forgot the sleeping bag, just catching up now

Thanks Ross but probably more arse than class

I believe Paul Haese has an 8" he'd like to sell ...

The majority of the 10min binned X1 subs have eggy stars and where unusable.
The majority of the binned x2 10min subs are ok, go figure

Well done mate.
It could do with some star colour, long subs and binning wipes out the stars. Here's the one I shot at Astrofest last year. The 4" tak just doesn't have the legs for it, it really needs aperture.
I have run the hasta lavista green fixer over it and have replaced the original image, it does look better, thanks.
