  1. Hi All I have recently bought a QHY163C and sold my original square QHY8 which I had had for a few years Nothing wrong with the QHY8 and I was reasonably pleased with the stuff I did with it...but itchy fingers/wanting to try something new/set cooling point/ heated window etc tempted me and I have just sold the QHY8 Most of the Photography I do is deep sky but I have had a dabble at Luna and Jupiter with various webcam type cameras and currently have an Imaging Source DBK21 AU04 (colour) What I want to know is how will the QHY163 compare to the DBK21 on planetary and moon pics? I have read that the 163 is suitable as a planetary cam as it is capable of high frame rates and 2x2 binning and wondered if anyone had used both types...ie a Largish Chip DSO cam that can also do planetary against a dedicated small chip Planetary cam. If I can expect as good or better pics with the 163 then I might as well sell the DBK21 Unfortunately due to weather etc other than bench testing the QHY163 I havnt used it all on anything yet. Thanks Tom Start new topic
  2. Hi guys, So finally after QHY sorted all the issues with UB2 I was able to capture some data to give a good test run to my new QHY163M, I choose something "easy" in Ha as this will be my primary aim with this camera, as I image mainly from my light polluted back yard at the city This was just a quick and dirty processing, to be honest I was like a zombie after a days work but I had to do it, it's been siitting for a few days waiting for processing, something is not very well I suspect with my dark or bias frames as I see a lighter band at the bottom of the image, seems like the amp glow did not callibrate out perfectly but that should be something or some bad frame in the stack so will have to see that in better detail...also yes, the microlenses reflection is a concern, very well visible on the brighter star, there is a simmetrical reflection around the star, I sure hope the gurus will find an easy way to deal with this in the future...maybe a PS plug in hehehe Appart from that, it need more frames to clean up the dim areas, but the details are quite something for only 480mm f/l. setup used: QHY163M SW ED80 at f/6 Baader Ha 7nm filter EQ6 mount autoguided with ASI 120MM and a 50mm finder Stack of 35x300 secs at Gain20 Offset100 USB traffic 5 Plus 15x60 secs + 10x15 secs for the core (still slightly overexposed) So this is a first "draft" and I will get back at it for inprovement when I'm feeling fresher must check the callibration frames and smooth out the background.

  3. Ok, now we´re talking Another batch of 36x300 secs frames out of the oven, this was captured in two consecutive nights with little moon impact so better contrast then my previous M42 image, also the callibration seem to be spot on as I can't detect any gradients or poorly calibrated residual glows, happy happy Good to know there's still ample room for improvement as this is just over 3 hours so will add at least the double integration time, let's see what it brings. Setup is the same: -SW ED80 with Altair Astro 0.8X reducer (f/6) -QHY163M -Baader 7 nm filter -EQ6 mount -ASI 120MM with 50mm finger for guiding Stack of 36x300 sec. at Gain20 Ofrfset100 USB traffic set to 5 (will lower to 1 on future captures to see if the amp glow is further reduced) Here on Flickr: https://www.flickr.c...eposted-public/ Hope you guys enjoy, Luís
  4. Hi all, Now that galaxy season is aproaching and i'm not sure if I can finish these two images here goes the mono only for now, halphas of the Rosette and jellyfish made with my usual setup, 175mm f/4.6 newtonian and QHY163M. if the weather ever clears I'll still try to get some OIII for these This time I used shorter subs of 180 secs and it seems to work rather nice, I'm still clipping a good deal of brighter stars but I don't think it's much to worry about, some star masks during processing works fine for me. Here goes the Rosette, this is only 39x180 secs with gain:20 offset:80 (make sure to check the full size version): https://www.flickr.c...eposted-public/ And the Jellyfish,77x180 secs. this one was made under mediocre conditions, bad transparency all the way, but even so it come out ok: https://www.flickr.c...eposted-public/ Hope you enjoy, Cheers, Luís
