Crazy Prof. I saw this on the news. Would have been an awesome site. Ray

This is what the Sun looked like at mid-day today. Apparently Saharan dust and smoke from Iberian forest fires dragged up to us by hurricane Ophelia. Greg

Cheers guys. The Hyperstar image is my most ripped-off image as this is the galaxy cluster where Zwicky first worked out there must be dark matter. Greg

Love them Red stars myself! Eric -
Yep I have used the RGB data as a pseudo Luminance in the past, and as you say Ray, apart from fine detail there is no discernible difference that I could see. Having said that I still shoot Luminance to get the best possible detail in all my shots. Shane

Exploring PixInsight lately and fiddling with some deconvolution settings, you can almost create an artificial luminance channel from the RGB data and increase it to 1x1 binning to give you the same effect as a 1x1 bin. Its almost indiscernible using a real luminance channel as opposed to an artificial one (with the image I'm using here). Admittedly shooting at 1x1 would certainly capture more detail, but deconvolution of an artificial luminance channel can get you there if you run out of clear skies. I guess it depends on how much you want to pull from your imaging session. Anyway, just worth nothing, if intricate detail is not part of the final image, you could get away without the lum. Ray

Happy Birthday Eric

Thank you. As far as astro presents, none so far. I would gladly be satisfied with a good night of seeing! Have to work all week long and my astronomy adventures are limited to Saturday nights...weather permitting. Thanks again and clear skies to you all. Eric One year closer to the big dirt nap! -

Half a Klein

It's probably going to be a LONG project lasting several months. I think I might have a go at putting the Curta Calculator together Greg -

Okay, I didn't notice that. Pretty clever ornament. What's next? Ray -

It is waterproof - but it won't hold any water as it is fully open on the side Greg -

Is it waterproof? Would look good with a colour liquid inside it. Still a nice ornament. Ray -
Just printed out a half-Klein bottle in Rigid.Ink Natural PLA. I left the brim on the bottom as it makes a nice stand. However - the brim is also REMARKABLY TRANSPARENT just like glass. I know this is due to it being printed straight onto the glass bed - BUT - it has now prompted me to see if I can print out a transparent single-walled Klein bottle using this filament. We'll soon see in a few hours Greg

lol, mate what an annoying little problem that was. Nice fix buddy. Ray

Who wants to count how many 90 degree corners are in there? Wish I had room for a 3D printer. Ray

All is good in the world once more, after a trim all looks good with round stars. I tried slightly different temperature settings as well and all still looks good, now I have to wait for our Lunar friend to bugger off so I can get back to imaging. Shane

Update: heater came off reasonably easy, so I thought I'd have a crack at trimming it while it was off. Took to the inside with a dremel and made the ID a bit bigger, now there is no overhanging fluffy edge. I will re do secondary collimation and try it yet again when the opportunity arrises. Kendrick state that these heaters are not able to be trimmed, with a knife or scissors I agree with a dremel it works and I have tested that it still operates. It's a pity that they couldn't get the sizing correct in the first place. fingers crossed. Shane
