Re: Powermate x 4/5 with a zwo 120mm camera

The ZWO support forum can be found at: http://bbs.astronomy-imaging-camera.com I am using ZWO ASI 174MM together with TV 2.5x powermate on Lunt 50 without focussing issues. No idea though with 4 or 5x. Given my standard seeing, the 2.5x is sufficient for me. Do have cheap 3 and 5x barlow, but not gi...

Re: Noise, Firecapture and imaging questions

Very interesting discussion, eyeopener.... Yesterday morning did some trials on moon as well following this topic... with ZWO ASI 174MM camera. Looks like Firecapture not consistent in "always writes 16 in header". See my txt files attached. in AS3 processing 16 rather than lower (10 or 12 my cam sh...

Re: First attempt Lunt 50 DS + ASI 174MM

Hi, In my last picture (see settings used under picture) my Gamma was at 50, so seems I found the neutral setting for that one. Since lower than 30 on Gain gives me almost black screen, I finally worked with 42 as setting, relatively close to 50 as _Zakalwe mentioning.. The seeing condition is influ...

Re: First attempt Lunt 50 DS + ASI 174MM

Hi Robert,

That is a good one to try as well, as DS went on to never be taken off anymore.... So have no clue what SS FD bringing me with this cam, as
with Skyris 132c I did not have this problem on SS and DS, but the ASI 174 is a different game as it seems. Perhaps because of larger chip ?

After just the proms, now time for the disk + proms from the same avi set shot on 11 November. Shadows/Highlights helped me to reduce the ghosts a bit, but still not to the level I am looking for. The attached pictures are yet my first attempt to make (almost) full disk + proms combined.. Wondering ...
