M27- lets see your pictures.

Recommended Posts

Another M27 - this time just a single 10 second sub with 10" F4 Newtonian and Lodestar X2 camera.

That's very impressive for just 10 secs!

I now have the RASA back & I'm experimenting with the capture in narrow band. The power of the RASA is amazing me. I have a very poor sky generally with light pollution. The sky as you know at this time of the year is not dark but take a look at the image below in OIII. It has no correction at all and is only 6 90 second exposures. The detail it has captured has blown my socks off- it would have taken hours with the previous edge- even at f7 to get the detail recorded in 9 minutes- I can't wait for darker skies!

Don't be too hard on yourself. That is a nice image. The stars are nice & round so the guiding is good & you have kept the colours of the stars intact- that is something I struggle with from my light polluted skies. What equipment did you use- the field is quite flat.

I finished the OIII last night & this is the image stack I will be working with- this 117 90 second exposures with the RASA using the SkyX direct guide & an ST80 with lodestar X2. The filter is a fast Baader OIII to work at the focal ratio of F2.2. I have not flat fielded or BIAS corrected the stack yet.

Let me know what you think- I'm going to capture the HA next.

Here is a quick HA/O3 composite that is a work in progress. I have no S2 or L data yet!

This is my last week's effort; two hours (39 frames, 4 minutes each), with an Atik450 OSC on a 6 inch, f/5 newtonian. It is an ongoing project, and I plan on reaching 6 hours.

I'm a bit baffled by the SII photograph. This looks like you have photographed a black hole. I'm photographing in SII at present (I took 30 5 min subs last night) & I see a nice dumbell- did something go wrong in your picture?

OK, here is one from a testing session on my local society's Williams Optic FLT110. 6 x 5min RGB only with an Atik 414ex. Seeing the outer clouds in some of these images, I am definitely having a more concerted effort with my own kit from home - amazing.

I added the S2 to the set of data & obtained the following result. Processing is very rough so I will rework the data in PI when I get the time.

Here is my m27 from last October.  Binned 3x3 using DSS.  Processed in Pixinsight and Photoshop.  1600 ISO with an at the time unmodded Canon t3i.

isnt it amazing the differences of the same object -i know beauty is in the eyes of the beholder but this is like looking through the eyes of other beholders. great images from all.

Well after last night I can contribute my own M27 for real! I managed to get the red nebulosity too. This is two images, one to accentuate the blue and one to show the red, superimposed - probably not the best way to do it, but I couldn't get both showing clearly in the same picture otherwise.
