No pictures yet with the new RASA- Sorry!

But.....post your images of this amazing target. I want to review your collection & get ideas for the M27 imaging project which I will begin this season. Remember last year I asked you to post your images of M1....some fine examples were posted...please do the same for M27...historic & ongoing.

Clear skies to you all

Oh, alright then...  This is from 2013, about two hours of RGB with a 127 Mak.  At one point I was quite happy with it.  Now I've started wearing glasses I'm not at all happy with it :(

Deep one from Freddie there!  :icon_salut:

So here's the question, is it red and blue or red and green???  Probably because it was red and blue in the first images I saw of M27 that's how I tend to like it and that's what I get using my routine colour balancing procedure. However, this is hardly a proof! I associate red and green with Ha-O111 renditions and maybe DSLRs tend to give that with their double dose of green filters?

What do you folks prefer/think accurate?

Dear Olly & Freddie,

Respect.

Ur image makes me want 2 quit astroimaging.

Feel like standing at the very beginning of the learning curve and gaping into the night sky.

Here is a DSLR image witha 60 mm scope. dont know why its more red and green.

I'm undecided on that- hence my turquoise rendition.

Fantastic pictures. On the subject of green according to the site where I downloaded HLVG it states that there are no green astronomical objects- green is seen as noise pollution & should be removed. I'm not sure how true this is as I like green- just not as a cast all over my M13 picture!

Most of us have seen the traditional out of the box M27 picture. I'm interested in capturing the faint outer shells & indeed some of you in these pictures have successfully captured this.

Now for my challenge & I really don't know if it is possible from my light polluted location is to capture the faint outer shells of the nebula. I have a fast astrograph. I'm not sure if the faint shell is RGB or narrow band data- let me know those who have captured it. I have a filter slide for the RASA with fast Baader narrow band filters good down to F2. This forces me to go with my Atik 460 mono camera (heaven forbid) I could try, when the sky gets darker, sets of 50-100 subs in each narrow band filter. I'm not sure if standard LRGB filters will behave at F2.2 but I can give them a try as well to obtain the full spectrum of data.

The RASA is also fitted with the official "cost an arm & leg" Celestron Astrodon light pollution filter but I still get heavy gradients which can be removed but it's another pain that might get better when the sky gets darker.

Keep your pictures coming. My mount is having a stability upgrade in the next few days. I'm going for Parallax rings mounted to the versa plate. I've just installed a sky watcher 80 mm refractor to use as a guide scope and this has the Lodestar X2 firmly screwed to the end with a C-mount adapter (must better than using the X2 in an eyepiece holder)

i have started to get some of the outer shell of M27 and M57  and i have a white street nearly over the top of my Shedservatory, and 4 others surrounding my garden and i live at  the south end of a large town (thankfully not in the middle) but LP is still quite bad.

i do get severe gradients due to the LP even with oiii and lrgb but not with HA so there is hope no matter where you live.
