first decent dso image

[greenkat]

Just thought Ide share my first decent image of M57 with you

about 15 x 15sec images with DSI-C on ETX90PE using drizzle (not sure if I did the drizzle right lol)

stacked in registax and altered in photoshop

If anyone can make it look even better, please feel free

Well thats a start Greenkat......

Focussing is a tad out, once thats sorted out, take more subs with a slightly longer exp time and you will be well on your way......

I have never used drizzle when stacking my images so i cannot comment there....Hopefully somebody will be able to help you when it comes to using drizzle when stacking and with any other help you need......

Cheers for the comment Lost

Hopefully I'll get polar allignment a bit better to take longer exposures,

As for focusing, I was in and out like jackinabox trying to get best focus using electric focuser

This seemed best I could get , I try harder next time

Good start GK. just a few little things to sort as been stated , but looks to be well on the way , yes try and up the exposure a little more , keep doing that till you find your sweet spot,

nice start there GK, looks ace. if you ask Cloudwatcher nicely when he's around i'm sure he'd fiddle with it for you

Good start.

I would drop the red level down a bit in photoshop tomake the sky look more natural.

For focusing I use a Hartmaan mask, before using software to improve it.

The Hartmann mask works a treat though, I used this template generator to make mine:

Can't resist an offer like that! Unfortunately lunch is now over so all I've had to do is darken the background and play around with saturation levels plus a bit of blurring. Looks like there is quite a bit of detail in the 'Ring' to be brought out.

Very good first DSO indeed. :thumbup:

Cheers

Click as usual.

Its a good start - no stopping you now!

Well it's certainly as great effort and one to be proud of given it's quite a tricky subject to image owing to it's size in the FOV so Well Done!!

[Aza]

Nice work CW

[greenkat]

Nice one CW, thanks for improving it for me

Looks much better now :hello1:

I'll have a mess with the original again, see If i can get anywhere near yours

You will get there GK and when you do there will be no stopping you
