M17 Swan, M27 Dumbell and NGC7293 Helix

Here's three from last night under surburban Brisbane skies. Great conditions and company (cheers Allan).

All images using the DSI II pro and Meade ED80. Exposures were guided 50x1min.

Thanks for looking.

Peter

Nice work Peter, as set of lovely images. I was outside too last night, although in our suburb (Holland Park West) we had small patches of thin cloud that seemed to just boil up out of nowhere and on several occasions I lost the guide star so had to temporarily abort the process.

That’ll teach me to sneak inside to peek at the Olympics!

Cheers

Dennis

Thanks Dennis - I think we were lucky with the conditions over in the West. There was a large bank of cloud to the South that threatened all night. I had one of those magic nights where everything seemed to work. I also managed to avoid my usual mistake of trying to do a goto with the guider still operating. Not sure what temperature it got down to but I certainly wasn't preapred and had to pack it in around 1am.

Looking good. I'm impressed you could get anything of the Helix in the burbs'. I've never had even a hint of the darned thing. Are you using any filters for LP?

Dan - These were all through the Baader UV/IR permanently mounted on the front of the DSI and the Meade R filter. There was quite a bit of sky glow and this showed up - especially in the Helix image.

Phil -thanks - I've had a number of attempts at this - learning something each time. Looking forward to seeing your results.

Cheers Alex,

We had a look at Jup on the night and it wasn't too bad early on. Have you considered the option of imaging and drinking beer at the same time? Do-able but focusing becomes more difficult.

Cheers Beren. It's an interesting tradeoff between length of the sub and having enough of them to get good S:N. Meade recommends 50 or more images stacked so going for more than 1 min subs makes for a very long night when you are looking to get RGB.

Alex - should be interesting to see how the C11 goes on the EQ6. My Motofocus arrived today so I'm expecting clouds for the next two weeks - sorry!

Peter

Thanks Jen.

Alex - you must have won lotto with that shopping list. Hope you've ordered some extra counterweights!

Gee Alex - with 14m you are going to get impressive image scale. Which half of Jup are you planning to capture first?

Pete.

I got a DBK31AU, with its bigger chip, I should be able to fit the whole planet in frame without too much trouble... I dont know how the mount will go accuracy wise... but hey... if it has to be only 10~11m then so be it... according to a few different programs i've used to calculate the scale, Jupiter itself should be around 690pixels in diameter Thats a DAAAMN big jupiter..

I've been impressed with the EQ6. Good luck and here's hoping for CS.

mmm.. I figure, if Mikes' EQ6 can hold his 24kg 12" newt stable enough for 10+m focal length jupiter images, then my EQ6 can hold my 12.3kg SCT and do the same....

Not to mention your setup... 10" + ED80 + side by side bar + cameras... (where did you buy your side by side bar?, BTW... im waiting and waiting and waiting for mine and im getting over waiting)
