Rosette Nebula NGC 2244 centre

[Fay]

26x300, Meade 8" Astrodon 5nm ha, TV fr. i needed more but the Rosette went quickly into the SW. i had to delete 4 subs, as not too good.

I should have used the SW120 as there is a lot of interesting things around the centre., quite pleased with the result, but a bit soft and needed a lot more subs.

Very nice Fay!  You have some lovely detail and a good amount of contrast there.

The leaping puma (upside down) is looking very good.

Thanks Mark, I did not know that was the puma!!!! good job I got it!

Very nice Fay, you have some very pin point stars there, is this because of the 5nm filter or did you perform some star reduction action?

Could be a tad too much sharpening but it's come out very well Fay.  Nice round stars too - guiding looks to be spot on.

Did you say 'soft', it (the image) doesn't look like it to me.

Fay, very nice. Nice detailed dark nodules and blobs, you'll be doing the Pillars of Creation next.

thankyou, no star reduction Carole.

Must be the 5nm Astrodon filter then, Sara uses those and gets really small stars too. But they are so expensive.

It's true what you say about the filters but you need good focus first.

Sara doesn't live under the Jet Stream.  Unfortunately, we do.  Star size is more dependent on the seeing than on any other factor.  On a good night you'll get tight stars: on a bad night you'll get bloated stars. I'm guessing Fay was imaging the same night I got a half-decent image of Venus.  But 5nm vs 10nm filters will certainly help the nebulosity contrast against the background.
