Not sure if you did much to shrink the stars Greg but this image seems to suggest your star halo issues were with the TEC scope system and not the Trius..? This is also suggested by your (excellent may I say) CDK17 Thors Helmet (coming soon?)
Very nice horse head that like the solid image scale...actually it's quite similar to my latest actually...hmm? wonder if you will get hammered for the garish bold hot pink/magenta too
Too many colourphobes out there

Hot pink is the new red! I agree the stars were pretty normal in the subs.
I am thinking the Trius is more sensitive (as it is with every other wavelength) to IR. I am wondering if the bloat in bright stars with the TEC180 (not all images just those annoying ones with bright stars in the field) is from IR. Perhaps I add an extra IR filter to the mix? Worth a test. Not sure how to implement it though.

Sorry but yep, it's gotta be the TEC I recon, doesn't happen with the CDK17 or my AG12 (which has a 4 element CC) ...remember, it aint no Starfire

Hehe don't forget I have an AP also! So perhaps. I guess I'll know when I put it on the AP. Its possible the AP is corrected over a wider wavelength range. Or perhaps a simple Baader UV/IR cut put in front of the camera and use my clear luminance filter may work??
Hi Greg,
that's very nice indeed - it's so sharp & noise free.
I wonder if you could post a pure Ha mono version.
( assuming you haven't already in an old post?)
I'm sure the Ha would have more detail especially of the curtain structure.

Beautiful image, great detail.
Fantastic shot, Greg, well done.

Yes it is quite detailed.

Clear skies Ken.
Sometimes I use 2x2. 4.54 micron pixels at 2x2 become 9microns which is about optimum for the CDK17 at 3 metres. At 2 metres its still good as well, so there is a choice there. 2x2 on a 9 micron pixel is a bit much.

Thanks Fred. I like that earlier one as well. That was about 20 hours with the TEC180 and down at my dark site, so yes it was quite nice data.

Like the colour tone too.
