Certainly interesting imagery you've been posting of the universe recently, something I have never been called on to do, so I know nothing of the techniques deployed here.

Am I reading this right... this image was in fact made up of 123 separate 30 second exposures and then combined with software?

If so how do you meter for such an exposure? or is it trial and error.

I'll be that someone... it means Lens Buying Addiction, it's a condition suffered by many here on the forum and to date has no known cure.

Now that I know what "LBA" is I must say that I could resist up to now. I started doing astrophotos because I wanted to find out how far I could get with "normal" DSLR and lens equipment. That was 14 month and 20 starry nights ago. I have bought old prime lenses for small money in the internet meanwhile.

My actual pictures are shot with a 400 mm lens from the 1980ies, not with an 8" Newtonien Telecope

You are right: 123 pics (best out of 190 or so) shot from my balcony.But it is not trial and error. It is catching as many photons as possible at the lowest possible ISO without exceeding the exposure time so long that you get trailing stars. Stacking the series brings down the noise and increases dynamic range. I shoot series of as many pics as possible using a remote timer control in bulb mode. There is actually a discussion in the Astrophotograpy group on this topic.

Fantastic capture mate. I first gave this a crack a few weeks ago, I was happy with the results but they looked nothing like this stunning shot, well done

Great capture.

When I posted this image in 2015 I stated that I could resist that LBA disease. Meanwhile I have sold that good old 400mm F/5.6 lens and acquired a 80/480 mm and a 130/910mm scope plus 2 flattener lenses and one reducer lens. So I am defitively infected after all !

Thank you both for the nice words!


Cheers

P.S. I should look if I still have the old data files and see what comes out with 2 1/2 years more processing practice....

LBA and AstroPhotos

Every time I see images like this I get LBA. Every time I spend time on PentaxForums, I get LBA!

Although, I do have a nice big 14" dobsonian with the T1 hardware to connect to my K-3. So far, that has kept my LBA under control. I just need to get life out of the way so I can exercise it
