Welcome back. Last time I saw your video was n WO GT81. Impressed with that I bought GT71. Nice presentation about the new star reduction method. I’ll definitely try it out. Subscribed, so that I don’t miss any of your videos 😊. Thanks for this video.

thank you sir. I will be subbing back as well. the GT81 is an amazing scope. its my main rig now. sold the hyper star. the gt81 did have to go away for a few months for repair but its back and better then ever. working on an update video now.

@@easyastroimages5818 I would prefer to get Edge HD 800. At least it can be used for observation as well. CS!

Thanks for this helpful video. I'm in the same exact 'boat' with my 8" and 11" HyperStar (v.4) scopes/lenses. The 11" is pretty well sorted as far as star shapes in the corners but not the 8"...! After much time with calibration adjustments including minimizing sensor-tilt and using the 'Hotech Advanced CT laser' cal tool I still have comet -shaped stars in the corners. I'm using the large sensor ZWO APS-C 2600 which will accentuate the issue but maybe I have a less than perfect HS 8" lens. I was hoping Bill's new PixelMath star reduction tools would minimize my problem with that scope but also tighten and round out corner stars a bit in general. I notice you are using the tool with linear images. Adam Block comments in his review it might be better used with stretched images? What do you think? Keep up the great videos!

its tough man. you can see this really helps. its a crutch but it makes things way less stressful knowing you can salvage a lot of data you might normally throw away. I've moved away from hyper star now and rasa. id love to come back once I hear that Celestron is making a good batch

@@easyastroimages5818 Thankfully my 11" Edge HD is pretty good with HS but my 8" not so much. I didn't think it was the Celestron scope itself but just the other issues of sensor tilt, back-spacing, corrector plate centering and possibly the HS (v4) lens itself.

@@easyastroimages5818 Bummer... Bill's Star reduction doesn't really round up or correct my corner-stars after my initial testing... It does tighten and diminish them, and the stars look very natural, so it seems considerably better than just combining starless+stars in PixelMath in that regard. Now I'm trying to figure out the best way to use it after doing most of my post-processing and aggressive stretching, etc.

Re method 3, it works better on non linear if you want to give that a shot

Hey bill thanks. That is what I’ve been doing lately at the very end when they are added back in!! Thanks for your amazing work
