Sagittarius Panoram in Ha

[multiweb]

Here's a 3 panel mosaic at F/5 on my 5". Meant to do 6 panels to include M20 but the clouds rolled in around 12:30am so that was it :whistle:
2 panels are 10x10min and the third only 3x10min due to clouds.

I stitched them in PS3 with the standard merge. Calibrated and flat fielded. It's the first time I tried using the QHY8 without the nose piece as to minimise the amount of glass in the optical train and internal reflections. So basically the sensor was exposed to all the air in the 55mm/2" spacer until meeting the glass from the MPCC. I blew dry the cavity with a hairdryer prior to assemble it and didn't have any icing or fogging problems. Fingers crossed. ;)

It's amazing how much more signal you get in when you cut down on filters and glass surfaces. :lol: Hope you like them. Bit noisy in places but focus was good and held for a change. There's a big one at: http://www.multiweb.com.au/astro/sagittarius_pano_f.jpg [5MB] . Thanks for looking.

Very nice Marc - very nice! :thumbsup: Yep, a bit of noise in places but nicely processed and great detail! Are you going to go for some colour at new moon?

Cheers, Marcus

May be a bit of noise in some parts Marc, but the other bits are pretty damn smooth!!!!
Great field of view - and nicely pieced together.
Lovely stuff...

Very nicely done Marc. It's really frustrating when something comes in the way of completing a mosaic however the field you've captured sure contains some interesting detail.

Marc,

That's really beautiful. Lovely pinpoint stars, too.

Which hydrogen alpha filter are you using? Now that my new gear is almost on its way, I would like to maximise my investment by spending time out whenever I possibly can; even when the Moon is out and under horrible light pollution. :)

Whoah that is nice! Wow, oh wow, I *really* like this shot. Are you OK with me downloading the jpg and getting a print of it?

Very, very nice, Marc. Little noisy in amongst the stars but nothing you can't fix. Lots of detail...well done:D:D

[strongmanmike]

:eyepop: not bad...not bad at all, very cool image, doesn't need colour, looks great as it is :thumbsup:

Very high class looking image

That is beautiful Marc, top stuff mate.

I know it's a 3 panel mosaic but you've pulled it off nicely to make it look like a single shot.
The large shot has very nice detail in there.

:thumbsup:

Marc,

Thats a fantastic image. What noise? There must be some obviously by the comments but looks smooth as anything to me. Does the Ha filter remove the moonlight so its as if you are shooting with ni moon. If that is the case I want one. Well done on the mosaic.

Marc, awesome, and done on a Newt!

Thanks Marcus. :thumbsup: No I don't think I'd be able to match the stars to do a blend with this. :whistle: Next new moon I'd like to try to do a couple of galaxies at long FL weather permitting.


Thanks Doug - Ha rocks ;)


Thanks Peter. I checked the full field afterwards and realised that M20 is just on the edge so if I framed bit lower I would have got it in :P oh well...:lol:


Thanks H. I use a 2" baader 7nm. LP? Moon? What moon? ;)


Sure Dave. :thumbsup: I'll upload a full quality resampled TIFF file for you to download. Will sent you the link when done. :)


Thanks mate. Yep, there's a fair bit of noise in the dark areas. That's where a dark site and new moon week-end wins hands down. ;)


Thanks boss! :thumbsup:


Thank you. :thumbsup: I didn't too much to stitch it. PS photo merge works quite well and it does the job . Not as precise as what Bert does with Registar and a master frame but I don't know how to use Registar well. :whistle:


Thanks Mark. The Ha filters a lot of unwanted light but strong moon glow will still affectyour pic a bit, especially sky glow in the dark bits (grainy dark areas)


Thanks David - glad you liked it. :thumbsup:

Thanks Ken :thumbsup:

Thanks mate. :thumbsup:

[AlexN]

Lovely Marc! A real winner!

I think adding some colour will give it a real punch, however as Mike said, she's a beauty as is! even if you do add colour, keep a copy of this B/W image for its simple yet striking beauty!

Well done!

[gregbradley]

Very nice shot Marc. You put in some real effort there and it paid off.

Greg.

[multiweb]

Thanks for the encouragement Alex. :thumbsup:


Thank you Greg. :thumbsup:

[toryglen-boy]

:thumbsup:

Excellent work Marc, you've done a fantastic job on that mosaic.

Cheers

[David Fitz-Henr]

Excellent image Marc - quite sublimely beautiful. Looks like I'll have to add a Ha filter to my shopping list (this sure is an expensive hobby!).

[multiweb]

Thanks Duncan - glad you like it. :)


Thanks for the comments Ric :thumbsup:


Thanks David. :thumbsup: You don't need Ha at bowen do you? Skies are pretty good there. I should be up at Crago Saturday coming. Looks like we may get some clear nights. :)

[Benny L]

they call it Astro-no-money for a reason! :D

Excellent shot there too :)
