Medusa, I got some more data!

[simmo39]

With another clearish night and with Ollys pointers ringing in my ears I got another 100 subs to add to the other data I had. Still needs a lot more to get the best out of this target but I think the image is going in the right direction. ( No not the bin! lol ). So here it is 200 x 60s subs.

C and C welcome.

Thanks for looking again.

Another slight tweak,

It's a nicely processed clean image.  You will probably need a few hours more to reveal the faint outer nebulosity

Thank you,  I hope to get more but I think that will be next season as its getting close to next doors house. I just hope we get better weather then too!

This is a great start on this beautiful target.

My apologies, but I haven’t been here in quite a while and was curious about what equipment you used.

My weather has been poor and this was my last target from my B6-7 backyard and I only selected it to try to test new guiding parameters. Never had noticed this target before and wow, it is beautiful!

I was lucky enough to catch almost 7 hours over two evenings and can’t wait until next season to catch more data.

I believe that you will see a significant increase in detail with more time on target. 
This nebula is very dim and very stubborn to give up details. 

Best of success!

My attempt so far.

Hi, that is a fine image of the target. gives me something to aim for. I used my Askar 400 with its FR and my ASI2600 c with no filter fitted. I was going to put my Optolong extreme filter in but I was being a bit lazy and went for it in just RGB.

[MartinB]

You will need that filter to pick up the faint stuff

I thought I would, I wont be so lazy next time and will fit my optolong extreme. It will have to wait till next season though.

Super project. Your background sky is looking decidedly brown on my monitor so a background calibration might be in order.

Thanks Olly, depending on what pooter Im using at the time I do get a little variation in colour. One seems to give me more green and although on the one Im using at the moment the colour looks ok to me Im sure if I look at it on my main pooter it will look brown as you say. Ill have a play later and see if I can sort it.

For an objective measurement I checked the background brightness per channel in two places using the Ps Colour Sampler Tool (eyedropper menu.) I check these values regularly when processing.

It gave R40  G30  B19 and R38  G29  B19. A neutral sky would have parity in all channels though personal prefences also apply. However, the numbers do say 'red high and blue low.'

Your promising image reminded me that I should reprocess my image of this object from two years ago using the new XT tools. It was 12 hours of RASA 8 data using the IDAS NBZ filter on an ASI2600MC. This is a great NB object, so I suggest that you put your L-extreme filter on next time to get to all that Oiii and Ha. As you see, there is also a lot of Ha in the neighborhood if you go deep enough, so adding subs pay off.

Cheers & CS, Göran

Thanks Goran, That is a great image. I will give it a try but I think I will have to wait till next season.
