Description

A relatively wide field view of this diverse area, including three prominent and different deep sky features.  The most notable and commonly photographed feature is NGC 6946, otherwise known as the FireWorks Galaxy.  This name is given to this galaxy because of the many (9) supernova associated with it over the past decades.  More than any other.  Based on just a guess and my experience perusing images here on AstroBin, the other most photographed feature is Barnard 150 and its cousins, just below it in my photo.  Finally, the fine open cluster NGC 6939 prominently near 6946.

I find that 6964 is an exceptional galaxy when imaged with longer focal length scopes, but is quite a bright galaxy and holds its own vs. the open cluster.  So I sought to frame this along with Barnard 150 and friends.  The whole area is rife with more transparent IFN.  It has been stated that these clouds impact the galaxy and therefore results in a rather reddened appearance overall to the galaxy.  That may be, however, I find that the IFN that I can pull out during the stretch seems to be at a local minimum just in the area around the galaxy.  I suppose that I could have stretched this more to brighten up the IFN, but the integration time did not support such a dramatic stretch.  There is no differential stretch here between the dark and galaxy.  I just decided to accept the dark areas, as is, since I liked the deep colors presented by these in certain areas, without blowing out the galaxy, which is still very bright here.  Did not touch the saturation and stretched with the SPCC corrected image.  The open cluster has been slightly affected by my initial gentle star reduction, however, later stronger star reduction was done with a masked cluster.  Star reduction is significant here because I felt that the extended regions of the galaxy and the fainter IFN were negatively impacted by the dense star field.  The galactic halo is actually quite extensive as seen in the starless image (not presented).  With this image, one might believe that they could just be overlaying IFN.  But in a starless image, the structural features within the halo make it clear that this is affiliated with the galaxy.

I have gotten a fair amount of use out of my small (61mm) doublet (with flattener) over the last 6 months.  Some images in the bank so I can continue to present stuff over the long cloudy winter here.  But I have my eye on something with a bit more aperature, reduced to the same focal length, that I hope will yield a bit better "quality" in as portable a setup as the 61.  But for all the talk about doublet refractors of the low cost variety, I have to say I have no complaints from what I bought as a finder scope!  Yes, the expert will pixel peep my images with this scope and say that they see some color!  Heavens forbid!  And I will have to admit, that I probably spent all of 30 min getting the backfocus as it is, which I decided was close enough and never touched it again.
