Single frame 35 secs @ ISO 1600 @ f/l of 2000mm. Hugely cropped.
Some detail starting to show. For some reason, clicking on the thumbnail gives a
huge pic best viewed a @ 75% screen, but clicking on the paper clip gives a normal size pic
which is best viewed at 300% screen size.

Thanks very much Brendan; I was beginning to think that everyone
thought it was pretty ordinary. Perhaps real newbies don't recognise
it. You don't often see it close up in the beginners' forum. This was with a 2x Barlow. I must try with a 3X so I don't have to enlarge it so much, and maybe get it a little sharper.

I found difference between 2X and 3X barlow...very little, and, image gets dimmer with increasing magnification size.
There is probably a sweet spot somewhere, but I thought your image was pretty damn good. Quite well focused, some details popping out, good colour and a single DSLR frame! Wow!
Looking at some images thru goolge images.....yours is pretty damn good..something to be proud of!
Thanks again. I will try with a 3x and 90-100 secs, or longer, if I can
get good enough polar alignment, and get rid of the clouds.
Done no imaging for over a month now.

Excellent for 1 frame Raymo. Bear with me. Given its only 35secs, what was your train of thought in deciding you would post a single 25 sec exposure instead of say 10 of them stacked?. That would be what, 4 mins?

Hi Fred, I'm a lousy digital imager, but am in my 63rd year of mostly film
imaging. I could see that astro imaging in this day and age could be a bit
intimidating for newbies, so several weeks ago I started picking single
frames from my stock of images of some brighter DSOs, and tried to get
the best result I could from them. I then started posting them, pointing out that passable images of some brighter DSOs can be obtained almost from the beginning, with just a tracking mount and a DSLR. I have always
felt that it's a good idea to learn the very basics before moving on to the
complexities of DSS, PS, darks, flats, etc.
I only have 5 frames of 3918, but will see what stacking brings out.
cheers raymo
Raymo,
You're sure having fun with the single frame shots. I was in JB HiFi the other day and spotted a new Nikon - 7200.
It has a max ISO of 25,600
Only $1,449. I'm thinking that maybe I should get one so I can get in a shot every time there's a 5 second break in the clouds.
Oh dear Melbourne
Anyway, well done Raymo. Keep them coming.
Robert
Hi Robert, Apart from trying to encourage newbies, as I explained to
Bassnut earlier in this thread, I had to find something to do as the weather here has prevented me from doing any imaging for about 5 weeks or so.
Nikon sounds good, but unless it is very very quiet, I would think that you would still be limited to about 6400. [ unless you cool it, that is.]
