Coal Sack via Startools

I selected this old image which probably would have been an hour thru the Nikon using 30 second captures at 1600 iso to see how Startools worked with a wide field.
I was as conservative as I can be and I hope the colour is not too bad.

I like that, Alex. You have some great definition, out in the depths of the subject matter.

Thanks for all your kind words.
It is rather satisfying to use a relativy cheap dslr and a $200 lens on say a relatively cheap heq5 using $60 software to get satisfyung astro shots first year back into it.

And raw beginers have an advantage seeing what a mug like me goes thru☺
We need more widefields so you new members if you have any please post them.

That's great, Alex! You must have guided that one if it was an hour? How did you guide it? No wonder I get no colour, my max exposures are about 15 mins!

Anything I have done with the Nikon D5500 has been only 30 second captures..and there have been ones with the camera and its 70 to 200 mm lens, the 80 mm and the 8 inch F5 but all have been unguided.
The object moves a fair bit when you compare the first and last frame because of poor polar alignment however Deep Sky Stacker does not mind.
Just be out there a little longer☺

That's interesting about DSS being able to handle stuff for so long. So why does anybody bother with all that complicated guiding. Seems a bit of overkill to me, with these new cameras I have a Synguider II and have never used it yet I can't get my head around having to have two programmes running if I do guiding with that popular PHD thing in one programme, and the camera software in another programme. Do people have two laptops whirring away under the stars??

One will do it.
You can work out the best times etc but all I am suggesting is if you want a long crisp exposure one way is a big stack...
I today had my best most recent Lagoon printed at officeworks and it looks rather nice for 30 seconds a high iso.

Lovely Alex!

30 - 60 secs works great until you get into narrowband

I wonder.
The main problem may be stacking.
I could expect a thousand frames for a start...and probably a lot more.
