Last Night's Astro Image

Yes, Saturn's still well on show - but why do my shots look so wooden and brassy in comparison?

Very pretty!

Might that be a consequence of them being made of wood and brass?

Ah. Sussed. Drat. Nothing gets past the eagle eyes of some on here.

Watching the Perseids shower last night , along with the streaks , at times there were just bright small flashes , no tails , like how can I say , coming down vertically and burning up ? Were these meteors too?

If between Perseus and Cassiopiea then they probably are head on meteors, but elsewhere they are more likely to be sunlight reflected off satellites or space junk. Search 'Iridium flash' for the source of the brightest of these (visible in the day, I'm told!)

I have about 2,000 photos from last night to search for meteors - can't say I'm hopeful, at least half are cloud...

I lied, it's 995 raw and 995 jpgs of the same thing.

Delta Aquariids ?

APOD caught one of those recently

Added narrowband hydrogen-alpha light (Ha) to the image from 4 August

Nicely done, Neil
I flicked back and fore several times between this image and 4Aug and from my perspective it seems to have focused/sharpened the smaller stars, in the top/left corner particularly. Thanks for updating

Thanks!

One effect of the Ha filter is to make the stars tighter as it letts through all teh red nebula light but only a small portion of starlight.

A very creditable decision.

I've just received the appended note by eMail, and thought it worth sharing

Hi Everybody,

That's interesting, I made the same discovery that FITS Liberator is an excellent 'stretching' program, unfortunately it wants to convert my images to monochrome so I'll see how he does it.

Best of the images from my first go with the scope I made. The focus is off (operator error not the fault of the scope) and the transparency was very poor.

Looks a very good start, Neil

MichaelG.

Thanks, I see he uses an approach that splits the image into RGB 'layers' and treats each as a mono image.

I will try that.

Beachcombing ?

I once modded a telescope micrometer gadget (made by Watson's around 1907) for a friend who specialised in measuring angular separation in multi-star systems. He told me that he and other astronomers with similar interests often kept spiders to provide fine threads for the crosshairs in such devices. (I'd managed to drill a hole for light passage in the internal framework without disturbing the existing crosshair).

But it must've been a helluva well-trained spider wove the web in that link.
