Hi,

Last night I made 22 exposures 10 min each to Ghost Nebula (IC 63) using Ha filter (Baader 7nm). The weather was perfect and the mount worked as a dream, best tracking i had ever.

Acquisition, guiding, stacking, calibrating in MaximDL, focusing in FocusMax and final processing (levels, curves, unsharp mask, reduce noise) with Photoshop PS2.

Set-up used - MN190 on EQ6/EQMOD, ATIK 314L+ mono plus True-Tech filter wheel, guided by finder-guider with SSAG, motofocuser controlled by SELETEK.

Thank you for your feed-back. I will try to obtain some extra exposures this night.

The tracking of my mount (belt drive) was unbelievable and if it will be the same this night, I will try some 900...1800 sec exposures.

I made some extra exposures in SII and OIII (105 minutes each) and I tried a Hubble palette with them. Calibrated and stacked on each channel, then color combine in MaximDL, weighted like 2xSII ®, 1xHa(G) and 2xOIII(B) and then processed in StarTools (Color TAB). The result was amazing for me, being first time when I processed a color image in StarTools. The details are not so obvious but the color is present and if you look carefully on both images (colored and uncolored), you'll find all details in both but color just in one.

You decide which is the best.

Superb image - prefer the plain Ha version

      This has been a bit of a project.  Last year I worked out that my 200mm Canon F2.8 lens and ASI1600 would frame the whole of the Veil complex quite nicely.  I captured Ha and OIII data for the east and west nebulae with a Tak FSQ 106 and added this into the widefield image.  Although the Tak data had to be shrunk down it did add a bit of extra resolution where it was needed.  
      The difficulty for me has been the processing.  I have found it really difficult to tease out the faint wisps of detail and have tried the usual routines of micro contrast adjustments using curves along with Scott Rosen's Screen blend/mask inversion method but the results weren't great owing to the close proximity of faint and bright nebulosity.  I'd heard about the PI process tool for removing stars, Starnet, so loaded this and had a rare foray into PI.  This proved very helpful.  It was a luminence created from Ha and OIII using the 200mm lens with the Tak data mixed in.  Then the starless layer was added in PS with the screen blend mode at 50% opacity.  The nebulosity detail was so well preserved I didn't need a mask.  After blending I reduced the stars a bit more using the starless layer again and darken as the blend at 50%.  I should really unleash some of the stars to add a bit of "punch" but I've wrestled with this data enough for now!  I plan to use it further as I look deeper into the Gorgon that is PixInsight!
      Telescope: Tak 106 for E and W veils.  Canon 200mmL lens
      Camera: ZWO ASI 1600 pro mono cmos, Gain 150, offset 50
      Filters: Baader 7nm OIII and Ha
      E+W Veil 10x30 mins each channel for each nebula.  Whole complex 50x5mins for each channel
      Captured with SGP, calibrated, aligned and combined with PI, processed mainly with PS but PI for Starnet.  Ha mapped to red and OIII to both blue and green

      Hi everybody,
      i'd like to share with you the design, making and progress of a project my astro club endeavoring to. I'll post here relevant info in a run-up  to where we got to so far.
       
      Here is the mission: 800mm in diameter. That's it. A lot of inspiration out there but it needs to be able to do science. So it's a relatively fast Newtonian capable of tracking for tens of minutes.
      So we realized that we were facing 2 projects in one. The mirror on one side and the mount on the other. Shall we start with the mount? What's the best compromise in terms of ease to build and cheap components and the chance to have a stiff yet light structure. An alt-az, like the biggest telescope! - or rather a glorified dobsonian in this case.
       
      Ambitious? Definitely
      Any comment/suggestion is welcome!

      A quick sketch from the 1st September (sorry - date is wrong on the image). 
      M15 was still fairly low in the east but the central condensation of stars really stood out, even in a 5.5inch scope. The bright field star intruding on the edge of the image was distracting. If I had a tracking mount I'd have banished it permanently!
      A lot of the extended GC was on the threshold of vision and the resolved stars faded in and out. 
      M15 will always have a special place for me as it was the first GC i ever saw 😍 
      Thanks for looking. 
      Jack

      Hello, this is my first attempt on NGC 7635 with my skywatcher 250pds on an NEQ6 synscan mount. These are 7min subs stacked to a total exposure of 5 hours taken with my unmodified canon 700d and a skytech cls filter. No coma corrector was used as I haven't gotten one yet. I'm just wondering how I could make my images look clearer when zoomed in and improve them overall as I can see the image gets more blurry when I zoom in onto the bubble, should I use a higher magnification? Do I need to take more darks to get rid of the redness around the image ? Or perhaps I stretched the image too much in Photoshop? I used 10 darks, 60 bias and 60 flat frames. 
      Update: I have now further processed my image with greater care and got a much better result. 
      Thanks 
      Greg
