[TC_Fenua]

Hello, it's me again

I finished another batch of image processing, so here they are :

Gear : C14 with Hyperstar, modified 450D/XSi.

Processing : almost everything with PixInsight.

Settings for all three pictures : 30x30 seconds @ ISO 400, 30 darks, 100 offsets/bias, no flats, no guiding.

Trifid Nebula - M20

Omega Nebula - M17

Eagle Nebula - M16

Very nice collection. Awesome to think these were captured without guiding

30x30s... (15 mins total) @ ISO400... Unguided... Wow... Just wow!

When I was using a modded DSLR, I came to the conclusion that I needed to capture at least 8 hours of data to get a reasonable image, and now I have a CCD, I've upped that! A superb set of images to get out of just what would effectively be less than a single hour to capture... I'm guessing you're probably blessed with fairly dark skies in Tahiti?!

superb images!

Lovely images. I particularly like the Trifid.

Those are superb images. I would be interested to know how you achieve such good focussing - I presume at around f2.

With the focal lens of your scope this is incredible!

Thank you everyone

@ Michael H F Wilkinson : hehe thank you ! Well, the mount I use is no slouch At 675mm focal length, it really can track well. At prime focus, it stays easily for 30 seconds without guiding ( or PEC ) and that's 3911 mm

@ Andy UK : thank you And yes we got really nice skies in here At the international airport, for instance, you can still see the Milky Way Bear in mind that the Moon was there in those shots and I didn't use any LP clip-in filters I can't wait to try the Hyperstar around the new Moon and try at least 1 minute subs.

@ Cfpendock : I use BackyardEOS with come with a focusing module in Live View at x5 and a FWHM meter, plus the FeatherTouch microfocuser on the scope, it helps a lot

@ tilan_s : actually, the focal length isn't the same with the Hyperstar : only 675 mm instead of 3911 mm So much easier to have a steady tracking and no flexures !

Wow!! The trifid is simply stunning! I love those colours! Amazing really!

[ollypenrice]

Very impressive indeed, especially for the exposure time. I'd go for longer subs though. There is faint dusty nebulosity in the background which the Hyperstar should pull out easily.

Wow, it is really splendid images. Congratulations about all yours images. It is great to have a shots around 30" without any guiding.

That Hyperstar looks like a fantastic bit of kit! Best of both worlds, super fast or super long.

Very nice!

Fabulous images.
