This is an image of Pimis 4, an open cluster in the constellation of Vela, and the cluster is backed by part of the Vela supernova remnant.

The colour data was very dirty/noisy and not enough of it however; the weather has closed in, so it is what it is. There are some odd stars in the image which I think are due to my OAG encroaching too far into the field. It also looks like I processed it with a sledge hammer, I cannot seem to finesse the data into a nicer smoother image.

Yeah, yeah, you are all playing tiny violins for me! LOL! :lol:

Lovely!

Oh, that such a beast would fit in our field of view.

I reckon it looks pretty darn good and I wouldn't be too critical.

However I am surprised by what looks like diffraction spikes on the stars. I don't think the OAG prism would cause this, that would just create a shadow on the edge of the frame.

Cheers

From the writeup I expected a disaster. The image actually looks very good.

Thanks! :)

Yes, its a shame that one scope does not fit all. :thumbsup:

Thanks Bill, we are our own worst enemy, for sure! :D

Yes, crazy diffraction spikes for sure. I rotated the camera and filter wheel/OAG combo back to how I had it originally(and had no issues) and all my subs tonight show no signs of diffraction. One can only assume, as I will not be rotating it back to see if they come back, it is indeed the OAG.

The only issue tonight is guide stars are wobbling all over the place. :sadeyes:

LOL! Not a total train wreck, I just expected more from myself and the data. Thanks Greg! :thanx:

Yaaay! Learned how to multi quote! :lol:



Thanks Paul, your input is always valued! Cheers! :)



:thumbsup::thumbsup: Thanks Rick!



Amazing what an astro cam can do in the hands of a master!:P;):lol:

Seriously, I was hoping for some and wondered if I needed to go back and do Ha and OII although it looks like I have gotten away with it. :thanx:



Nice, thanks Martin.:D

Yes Mark, it is, to be honest. It has taken a bit of time to realize that.

Thanks for the positive comment! :)
