Atik Horizon - Horizontal Banding

Recommended Posts

Hi Guys, this is my first post so would like to say what a great resource this has been over the years. Any problem I've ever had the answer has been here. Until now. 


Just wondering is anyone else having a problem with horizontal banding on the Atik Horizon. My high gain subs have terrible lines across them which is made worse by stacking. The lines are also present in low gain subs when stacked. See attached pic of 1 300s high gain image.

Hopefully it's just my camera and not a feature of the product.

I realise this can be a CMOS issue but surely Atik haven't released a product with this problem? Certainly not at this price?

What software are you using for capture?  Have you tried it with Artemis just to make sure it isn't a capture software issue?

I don't know the answer to this problem. But I'm interested in this camera.  Hence my response here. 

You may be aware of this already, there seems to be more experience of this camera on the Cloudy Nights site than there is here.

I can see some amp glow on the left edge of the image in the same pattern i would usually expect for one of these sensors so I am assuming this is calibrated? I dont know if that could be it but I have not seen another camera with this issue before, might be best to just ask ATIK.

Yes i used Artemis for all images.

Stacking with darkRosette_Ha-reg-St.thumb.jpg.139d315686c6c2497b87d6de58651197.jpgs and bias removes the amp glow but the banding is worse. Attached 11 300s stacked. I contacted Atik 3 days ago and havent heard from them yet.

Ok that's good.  What power supply are you using, and what else do you have connected to it?

Using a celestron powertank. The mount is also connected. I ran some darks off a mains supply and the banding is on those too.

Ok well it seems the obvious things to check are fine.  It may be settings being that it is on lights and darks, but I've not seen this complaint on any posts relating to this camera, so it could be something else.

I would drop Atik another email, or even try calling them, as they are usually very good at getting back to you, so you could have slipped the net.

Ok thanks for your help. Ive emailed them again. Hopefully they'll get back to me.

Have you watched the youtube demo?

Steve Chambers showed this on the video, you just need more subs to get rid of the lines.

You will also find much useful info on the ZWO camera forum  http://bbs.astronomy-imaging-camera.com/viewforum.php?f=21&sid=1fd72c865036dc322ba9e8d4bc7107b3

This is mainly in relation to queries re  ZWO ASI 1600mm and banding noise which also has a CMOS sensor........  Although a different manufacturer there are probably some generic issues going on here.

Hi just an update. The camera was defective and went back to Atik for repair.

They sent me out a new one. Ive done a short test with it and the banding seems to be gone.

Thanks for all the replies.

Good news!  Sometimes it turns out that it really is the kit that is defective.  We tend to assume it's something we're doing wrong don't we! I hope you get a chance to use it and we see the results soon. :)

Glad it seems to be sorted. 

I did come across this http://www.astrosurf.com/buil/atik_vs_zwo/ that discussed two different download modes for the Horizon one of which can cause gradients.

Regards Andrew

 

Thanks for the reply. Good info in this for anybody with this camera.

      I scrapped all the Oiii and Sii data I previously took during a full moon (about 15 hours worth) and retook it all when the moon was a bit smaller at 76%.  Ha was taken during 98% and 67% moon.  All the lights were taken on the following nights: 12th, 19th and 20th September 2019.
      Integration times, all in 600s subs unbinned:
      Ha = 28.33 hours
      Oiii= = 5.67 hours
      Sii = 5.67 hours
       
      The Ha data is really nice, and unsurprisingly the Oiii and Sii is not as strong (or nice).
      I'm missing that (vital) step in my processing routine of getting the Sii and Oiii properly stretched to match the Ha, before combining.  I dont really know how to deal with the weaker data properly.  Any pointers would be appreciated.
      What I do currently:
      All the data is loaded into APP into separate channels/sessions.
      The data is stacked and registered against the best Ha sub
      This produces individual stacks of Ha, Sii and Oiii that are all registered
      Each channel is processed with DPP in APP and then saved as a 16bit TIFF
      Each is opened in PS
      Stars removed with AA and any remnants removed and tidied up
      I then open a blank RGB document in PS
      I paste Ha into Green, Sii into Red and Oiii into Blue
      Adjust the selective colour settings to get 'Hubble palette'
      Adjust levels, curves, saturation until looks ok
      All the Ha Sii Oiii data is then combined together in a single 'super' stack in APP using quality weighted algorithm to create a 'luminance'
      That luminance layer is adjusted using levels, curves, and NC tools such as local contrast enhancement and deep space noise reduction (using masks to apply as required)
      The luminance is pasted onto the above colour layer, and incrementally added using gaussian blur
      Cropped and saved.
       
       
      Here it is anyway   I haven't intended on any more exposure time for this one, but will consider it, if the expert opinion dictates otherwise!

      Hi guys, it's my first post here, so Hello!
      My synscan goto upgrade started to act like in this video of mine SynScan GOTO Skipping after being disassembled for few weeks in the closet. There were no such problems before.
      When it slews at rates above x3 everything is fine and smooth but as soon as it starts tracking at x3, it skips steps or something like that.
      My setup is eq3-2 on alu and SW 150/750 with Canon 700D attached.
      Thanks in advance for any clues or ideas!

      Ok, so this is a really annoying bug / problem that I have with my setup:
      From time to time, in non regular intervals the image my guiding cam (ZWO ASI120) send seems to get flipped / mirrored or looks like it's from a completely different patch of sky.
      When I'm paying attention to the guide images I can clearly see that the image seems to be flipped in some way.
      It only happens for 1 frame PHD send a warning ( No star found / Star lost Mass changed) and after that everything is fine again. My gear is all connected to a single USB3 Hub which then runs via powered USB3 cable to my Pc.
      I'm not binning and have the noise reduction off (though PHD might got hickups while processing) but it still happens. Sometimes there are minutes between two events sometimes it happens 5 times in a row.
      It also seems like it's only happening during guiding, I haven't seen it happen during calibration yet...
       
      I'm completely clueless what's happening or how to get rid of it, any help / idea is greatly appreciated.
