Look awesome.... I'm currently exposing the same object in my 8" SCT at f6... If mine comes out half as good as yours, I'll be over the moon....

Thanks, I look forward to seeing your image.

I suspect mine may be just a tad overprocessed but I have been struggling with the amount of red in my raw subs. I don't know whether it is my camera or light pollution but it takes a fair bit of playing about to extract the other colours and to produce a bright colourful image.

      Hello 
      I have a telescope -SkyWatcher Explorer-130P SupaTrak Newtonian Reflector auto Telescope  and it has a  heavy duty tracking device ( pic attached). I have had this scope for a few years and did pretty much basic with this and never understood how to use this device. I have the time now to spend with the scope during this social distancing time and I am totally unaware of how to efficiently use the tracking. I know how to move up, down, left and right. I don't think it has wifi and it looks very basic ...please can someone explain how to set this up. Pleaseeeeee can someone help .......I have searched everywhere but I can't find any material on this.
      Also , If i buy SynScan ( with wifi ) will it work with my scope? Thanks in advance xx

      Because of the current situation, I have, as many of you guys probably have too, spend a lot more time under the stars when possible.

      It has literally been over a year since last I was out doing some astrophotography because of work.

      So here is my second take after the long break, NGC 3344 (The Sliced Onion Galaxy).
      Initially I thought it would be a lot fainter than it was, so it was basically a shot in the dark, of just trying to get back at doing this.
      But the final image actually showed a lot more detail than I would've hoped for!
      Spring lent a lot of clear night, but those seems to be gone already. I would've hoped for a few more hours to add some more luminance data to it, as I did have to push it quite a bit.
      I am not too happy with the shape of the stars either. Guiding was not very stable through the night, even though balance and polar alignment seemed to be good. Might need to update my Celestron PEC data? 

      Any advice or feedback is very welcome! 🤩

      Hi! I've recently acquired a new Astromodified Canon rebel XT and I've tried to take pictures of nebulas using it but I've noticed that there are these weird black artifacts that keep appearing in my images. Would like to know if anyone has experienced this before? Or are these dirt/dust specs on the camera, filter, and telescope glass? I've attached some of my edited and raw pictures for your reference. The black artifacts can already be seen in the raw image of the horsehead nebula and after stacking I think it got amplified. Anyway, advance thanks and I hope everyone's doing well.

      Hi all,
      For a long time I wanted to shoot this frame, probably from the early days of my astrophotography adventure.
      Finally after all these years I managed to get a decent result of the 'stuff' between these two beautiful nebulae. Fairly happy with the image but always looking for improvement.
      I hope one day to redo this all with a mono camera and filters. 
      Apart from NGC1499 , M45 and the Baby Eagle Nebula no idea what else is in the picture. If you happen to have an idea feel free to educate me.
       
      Some info on image and capturing:
      Widefield Pleiades to California.
      Taken over 2 nights with a total of 11hrs 25min integration.  
      With a stock Nikon d610 and Nikkor 85mm 1.8 objective.
      Tracking was done with the Skywatcher Star Adventurer.
      Lights and all calibrations frames were stacked in DSS.
      Processing was done in Adobe Photoshop CC using Adobe Raw, GradientXterminator plugin, HLVG plugin, Nik software plugins and Photokemi action set.
       
      Ken
