That's a stunning widefield image.  Well done!

20 hours of integration time - that takes a lot of dedication.

Thanks Mark. The integration time May have been a bit excessive. Not sure if I want to repeat it again. :D

That's a superb FOV.  You have managed extremely well any LP gradients from your site.  Well done indeed! 😎👍

Thanks Roberto. I think a lot of the credit has to go to Pixinsightand my Samsung 100mm lens.

Thanks Roger and Robert. Your comments are greatly appreciated. It was a bit of an experiment connecting up the Samyang Lens to the ASI294MM. I was really impressed with the performance of this camera and lens combination.

Clear Skies. (Well we can be hopeful)

I have the Samyang 135mm lens, and have been having a ball with it over the last 18 months.  My only criticism is that tiny stars are a little harsh if you zoom right in. 

Also I had a job joining it all together and my focus is right on the end of the focusser ring.  I did my recent Iris nebula etc with it.

Very nice Garrick, nicely processed. I'm tempted by one of those lenses, I've got the ASI294MC Pro so would get the same FoV.
