Danilo! I've been busy all week and just had a moment to drop in to see
if you left me any goodies-- WOW! How amazing it must be, for you to look through your telescope and see that! Again, thanks so much for sharing... susan |

How amazing it must be, for you to look through your telescope and see that! Hi Susan, If only we could look through a telescope and see that sort of detail! Unfortunately, that isn't actually the case and astro-imagers like Danilo use special cameras and 'stack' many long exposures. Then a computer is needed to process the result. It takes a lot of work and experience to produce images as good as this, so well done, Danilo (I think I can see the background 'flux' in this wonderful image!) Best, -- Rob |

Well now, Rob, you've shattered all my delusions! I'm scratching that
telescope OFF my Christmas list. I suppose the next thing you're going to tell me is that the beautiful colors in the Hubble images are faked..? Seriously, thanks for info. I always thought those long exposures were just so the camera could pick up the light... So, even if Hubble had an "eyepiece", and assuming I could somehow get in to orbit and peer thru it, I wouldn't actually be able to see the Pillars of Creation in the Orion Nebula..? (long pause) "Of course not!" she answered her own question after a quick side trip to Google. "The Pillars of Creations are in the Eagle Nebula. So, it doesn't really matter what you're peering thru, you're not going to see them in Orion..." (ahem!) At any rate, I now have a far greater appreciation of the effort that goes into Danilo's craft, Rob. So thank you for teaching me something today... (: susan-bit-of-a-dingbat |
