  1. Hi TingTing,

    My imaging train is a modded Canon 100D, a relatively light DSLR, fitted with a Skywatcher coma corrector. Also using an Astronomik CLS clip LP filter. Thinking of switching this to a Hutech  IDAS P2. The thing is.......the filter is about the same price as the 130 PDS......seems the wrong way round but there you go. 

    As you can see, I am still plagued with gradient and focus hassles. I've been using DSS and Photoshop CS2 and running the Gradient Xterminator trial. For galaxies and clusters it works reasonably well but for nebulae I seem to fall into deep kimshee.

    Star colours are coming out ok but I seem to muck up on curves and levels and colour balance.

    Take the M81/M82 shot, for example. My individual subs clearly show a red hue in the middle of the M82 "cigar shape" structure. After stacking and histogram stretch and saturation shift, I seem to lose any red in the finished image.

    Never mind, I'm learning a lot and loving the journey. Thanks to all in this forum for their inspiration ad tips, re balance. In time I'll switch to guiding and EQMOD and CCD but for now I'll keep learning my ABC and times tables, so to speak.

  2. Bloomin 'eck Uranium....I hesitate to post, having seen that last image.

    To hell with it....hello folks, this is my first attempt with a modded Canon 100D with Astronomik CLS clip filter, using the Skywatcher CC, sitting on the 130PDS, sitting on an EQ6 AZ GT.

    27 x 210 seconds with darks, flats, bias and dark flats. Unguided.

    Have managed 4 minutes unguided but playing safe. Totally incompetent but keen as mustard. Cheers.

  3. I just want to say thanks to the contributors on this topic. I have finally.....finally....finally....got good balancing with the 130 PDS with my imaging train (100D + cc). I was going daft but then I read the posts.....and then made up 2 x 500g home-made counterweights, secured them to a spare large dog collar (literally), and velcroed them to the mirror end. It has worked like a dream. Thank you folks.

    Now happy to recommence imaging with my EQ6 AZ GT. Cheers.
