  1. Lots of 'firsts' for me on this one:- first time with the Atik 460EX first time with a dedicated astro CCD first time with a mono CCD first time processing LRGB .......I started astro in 2011, using DSLR's & for the first 8 months, just camera lenses. I tell you all this so you don't judge the camera too harshly due to its inexperienced operator ;-) Imaged with an f9 refractor L: 4x300s+2x600s RGB: 4x300s Dark Frames: none Flat Lights: 12x0.5s (I think!) via each filter Stacked in DSS, post processed in PS CS5. I've only cropped the very edge to remove the registration marks, so this is pretty much the field of view I got & the resolution - albeit, I've saved in jpg to upload here. I am content with the processing on the nebula, I'm sure someone with better skills can do a superior job, but for me I was happy enough with it, BUT I have some kind of optical defect which is giving horrible spikes to the larger brighter stars. If anyone can advise how to best process these out, or point me to a tutorial or PS plugin that would be great - I don't feel like doing it one star at a time manually. I'll be investigating the cause of these spikes, but the optics are old & contaminated, so that maybe the cause, I just have not been brave enough to remove the lens cell to give it a good clean.
  2. I've reprocessed the data of IC410 that I captured earlier in the year. This is 24 x 600s Ha and 22 x 600s OIII - the OIII was captured using my FSQ-85 and the Ha combination of the Baby-Q and my TS90APO. I had somehow manged to combine the data using DSS earlier but couldn't get it to work reliably and so I ended up buying RegiStar to get the different field of views to combine properly. Scopes: FSQ-85 and TS90APOc Camera: Atik 460ex mono with Baader 2" filters Guiding: Atik OAG, IMG0H, PHD Mount: CG-5 Registered in RegiStar, stacked in DSS, and processed in PhotoPLus X4. I've had trouble getting the colour balance right as there is a fair of mount of nebulosity in the background; I'd be really interested in comments as to which of the following looks best. Thanks for looking!
  3. I had an unexpectedly clear night last night - the best for ages... I managed to get some SII subs for IC 410 but when that disappeared below my horizon I pointed the scope at M105 to see what I could get. Now the focal length of the scope I was using (Tak FSQ-85) is less than ideal and I had the narrowband filters loaded up, so this was just a bit of fun. 30 x 300s subs, L only. The pull out is obviously a crop from the main image.

  7. An unexpectedly short EAA session on the night of January 18 led to only one capture... it would have been longer but for the clouds, and I seem to have a problem with star shapes. This is from my Quattro 8", successfully used before, but with a new (to me) camera and imaging train. Here's a 20 second sub as captured on screen (Nebulosity) and then a post-processed image with 22 of them stacked (for a total of 7 minutes, 20 seconds) The problem, though, is with the star shapes: The image train is: Coma Corrector (previously used and absolutely fine) ZWO OAG (new for Christmas, but not in use yet, except as a spacer) Baader variable spacer Atik 460EX mono CCD cooled to -12C (this is 'Gina-cam', thanks @Gina!) Everything is threaded connections, I don't think it's tilt, and it doesn't look like a classic CC spacing issue. This is unguided, and certainly the PA wasn't perfect, but collimation was (I believe) good. The OAG prism was way out of the way from the long-side of the chip, so my hope is that this might be caused by the high wind that night? (Mount is an Avalon M-Uno.) Any suggestions/advice? I will, of course, be trying again in better conditions, if they ever arrive. Tony
