NGC292, aka SMC

[DJT]

Naked eye from the place in the sticks so gave this a go this weekend

NGC292, SMC (http://astrob.in/313415/B/)

The most bizarre imaging sessions though. The CCD was running at minus 25 on Friday then it was really pushing it to keep it to Minus 15 last night. I had to drop to Minus 10 for the flats.

That caused a few issues with darks so there are some artefacts I need to deal with once I do some more darks at Minus 15...

Usually you see this wide field with Tuc47 et al but the STL6303e doesn't quite get me there with the FSQ so framing could have been better.

Scope stuff: FSQ106N on an APMach1
CCD:STL6303e self guiding
16*300 L, 11*300 R, 9*300 G, 8*300 B

Processed in PI using new PCC colour calibration tool

Thanks for looking

That looks great David. :thumbsup: Got the colors spot on. I thought it would have fit in the FOV of the FSQ. :question:

Love it David! The high res is really pleasing, perhaps a little too much noise reduction but lovely all the same :)

[DJT]

Thanks but for the record I didn’t do any noise reduction at all? Dither and it’s a high signal anyway.
Interested which area you are looking at?



Cheers Marc. Really pleased about the colours. Am limited by the sensor size sadly. It’s just about the same as the APS-C I think.

Thanks

[DJT]

Aah..on the full res it looks like compression artifacts. Didn’t resample, just saved it down as a jpeg..likely to be the cause?

[Retrograde]

Very nicely done.

Looks really good David, lots of stars, you don't see many images from 6303 based cameras, so its a pleasant surprise.

Do what the Strongman does, if you are dithering, don't worry about darks.

EDIT: Its a bit bigger than APS-C more like APS-H, 27.6 x 18.4mm

[RickS]

Very nice, David. You need a seriously big sensor like a KAF-16803 ;)



That might be OK on a low dark noise Sony sensor, but I think you'll find that darks are useful on a KAF sensor.

[Atmos]

I found that darks were needed with my QHY9 (KAF-8300), not needed for my QHY22 (ICX-694) and DEFINITELY needed for my ASI1600/QHY163. Dithering helps with hot/cold pixels but it doesn’t help fix dark current nor amp glow.

Great shot :thumbsup:well done David.

[strongmanmike]

That looks pretty good Dave, with some nice stellar resolution form the little QN :D

Cheers Bill. Sometimes it’s a sod with blooming but it’s got a great QE and the thing just works.



Thanks!


Thanks Rick. Sadly I have run out of kidneys to sell for the time being but oooh..yup, need something..stop that..grrr




Thanks Louie. Seems to work!


Cheers Mike. Chop chop, get yours firing!

[rustigsmed]

really nice David, thinking of adding any Ha or O3?

[Ryderscope]

That's good David. Can see the Ha regions coming through ok as well.
