Simple quick 90 Min H-Alpha...man...love this scope!..perfection scoponified :)

Eta Carina Nebula (http://www.pbase.com/strongmanmike2002/image/166984211/original) Full frame, full resolution....

This was just a quick fill in image to check out the FOV, so may or may not complete a narrow band or RGB version...maybeee...

It is indeed very faint: the image is all black.....
Probably you uploaded a wrong (empty) image.

No,... no...there is something there...yep, I can see something....very faint but definitely something...

Wow...what a humongous field :thumbsup::thumbsup::thumbsup: FSQ's are very addictive....maybe you won't get over It.

Now you're just showing off! Lol:lol:

Took me 6 panels and 5 months to cover that much territory and create a mosaic of that region with my gear. (sigh) :screwy:

Very nice Mike, go on - make a nice colour pic, you know you want to! :D

That's huge, bigger than the Gladiator! We could zoom in well beyond 1:1 on tiny areas, like Gabriela Mistral, and it was still showing sharp detail. That's so impressive, tells such a big story about gas and stars and turmoil, no emoticon can do it justice.

A lovely vista Mile.
FSQ is an ultimate imaging scope. I wonder if the
FSQ130 maintains that quality? I don’t see much about it.

Your scope is too small and camera is too big :P Where's fun in that?
Ah, I remember, it rides on top of a proper telescope :D

Man, those FSQs are really nice scopes ... they just work.

Mike, you can’t just throw out a teaser and NOT do a HaRGB ;)

Ha ha thanks for the comments guys :thumbsup: was just a quicky, done around watching a movie and a series on Netflix and several cold IPA's... while the wife was out with the girls for a Friday evening :lol:...looking at it again I clearly pushed a little hard looking for the faint outer stuff, 90min with 4" isn't quite enough there.

Are you suggesting I should gather some colour data Simmon :question:...we'll see, it's early in the season for Eta Carina so plenty of time to find some more fill in time windows between imaging less boring objects I guess :P :)

Gotta love that FOV, Mike :thumbsup: Give it a few more hours. You know you want to :lol:

Looks great Mike,
are you saying that it's one 90 minute frame?

cheers

I bet even a tiny cellphone camera captures more in 90 minutes .....

MOAF (mother of all fields). :P Bit flat as you mentioned but can't wait to see the repro with all dynamic range and possibly some other channels. :thumbsup:

Yeah, yeah, probably will, since I have started..... :rolleyes:



Ah no...who does 90min subs :eyepop: :shrug:...not even Mike and Trish! :lol: T'was 9 X 10min subs :thumbsup:



The size, shape and even colour of the FLI ProLine-CFW-5-7 ensemble are indeed quite similar to a Nokia Mobira Talkman (http://www.zdnet.com/pictures/nokia-evolution-from-beast-to-beauty-photos/2/) cell phone circa 1984 :P



Weeell, I was referring to the sharpness of the field across the frame, not the dynamic range :rolleyes: :lol:...but you are quite right, with a little more data (should I decide to get any) and a repro, I will endeavour to display the dynamic range in a more pleasing way ;)

The fov is not that sharp. I was only referring to the contrast and dynamic range.

Ok you have lost me now...not sharp? what do you mean..? I think the field looks pretty flat (ie no coma or field curvature or tilt) :question:

Marc might be referring to resolution.

I checked your image (~3.5asp @ 9um) against half your FOV that I did in Ha (2.1asp @ 5.4um) (https://zbt1yg-dm2305.files.1drv.com/y4mdklsI9q-KwNJcQ3LkaqhG2XRM3XgeimZEdTCYFjWlwv 68NKd7DoaGmbPBLtoX1dRmZUeaHRKQLbrqZ cQDe_SB2MzobfqO8ipJHD5v9gDYJDe7qBXd YkPwLSfHHveRfWRhgwzvnc8SWcdfFVB9jj6 cubXAuJZjBNgDyhSOHeVz-DrJcOl6WmFkeCVBLDrkjSR2VRhGgppNYHLS b93Tb2xFA/ngc3372_FSQ_fff.jpg?psid=1)? Maybe the sampling difference is why I thought it was a bit soft.

Ah yep...thaaat cooould have something to do with it :) I swamp your field size though :P... but I do like your processing :thumbsup:(and I will try and improve for the future repro, I really rushed it what with all the beer and whisky consumed throughout the processing :lol:)...I should get one of these (http://www.flicamera.com/51.html) for the FSQ, but it would require bigger (expensive) filters :doh:

Wow amazing how far the nebulosity extends. Great telescope and lovely shot Mike!

Thanks Prickly, yes it is a pretty big and bright bugger but the faint outer stuff still requires some exposure and care with processing :thumbsup:

Another amazing widefield in the making Mike.

So sharp and detailed.

I love the new path you are powering along.

OK - for a minute there I thought you had gone for a world record sub frame.

M&T have routinely done 60min subs with their big fork mounted beauty...wonder if they have tried 90min :question:
