  1. Hi Please could someone suggest what i may have done wrong based on the stars in the crop of M42. This is after the basic PI pre processing and final integration. Looking at the individual subs prior to the last step they appear ok so i assume it is as a result of the integration step, or the star align ? subs were taken both prior to and after a Meridian Flip thanks Mark
  2. thanks - i shall keep looking to see if the re is anything i can do with the pre process
  3. again thanks, normally i would dither but last night APT was just hanging during the dither so i had to switch off or lose the whole run time. Darks bias and flats were included ( although it does look like i need a new set of flats )
  4. thanks for the comment - hardly stretched at all so perhaps it was the pre processing that has caused a problem
  5. Hi Does anyone have any hints on how best to process this, currently stacked, basic stretch and curves in PI. Spent a few hours hours on it today but i feel its out of focus and noisy however i am not used to this camera as yet so not so sure what i ought to be capable of taken last night with TS 65 Quad, ZWO 183C, aprox 2 hours of subs at 100secs
  6. Like the framing with the milky way falling into the Standing Stone - a very calm image
  7. i tried this myself over the last clear nights but didnt get anywhere near as nice an image . which camera by the way?
  8. Hi first attempt with OSC using the ZWO 183C Pro. struggled a little to get darks sorted properly as i feel the amp glow is quite high and no flats, but I dont feel it came out to badly - of course all pointers are appreciated 50 x 100 Sec subs TS Quad 65
  9. hi just going to run a new integration and will try to remember not to tick Master Dark optimisation, again just to try to understand what i am looking at - here is a master dark i ran today. any ideas anyone on why there are circles everywhere - just doesn't seem to be correct Or ? Camera is 2 days old so if there is an issue it would be good to know
  10. thanks for looking - i will see if i can find the post on Cloudy nights processing - was simply Screen transfer in PI nothing further here is a single Dark sub
  11. Hi Trying first light with a new ZWO 138MC Pro, testing darks i created a Master from around 10 taken at 120Sec -20 degree i expected some amp glow from reading other posts and reviews but can someone give me an indication if this as expected or ? seems greater that i anticipated thanks
  12. Hi having been away from the telescope for a few years i am trying to get back into imaging. spent the last few nights trying to grab some images of M33 as its one of the better targets available to me. only a few subs taken to test the rig but i notice that i seem to have either square looking stars or very intense stars. i have noticed similar on my TS 65 Quad so i am assuming i need to look outside the scopes themselves. i know how frustrating it can be to try to get everything working together so any pointers would be appreciated Thanks, Mark 7x180sec RGB no lum - quick DBE and stretch in Pixinsight Atik 314L Skywatcher ED 80 with reducer. Bart mask for focus PHD2 guiding ( although not so good as need to drift align) HEQ5
  13. Hi all Having struggled to make much headway with mono and filters I am going to have one last attempt at an "easy " target in M42, before I head back to the dark side of OSC I already had some personal success using my DSLR on this so have a personal reference Can anyone give me rough idea on the possible separate exposure settings to ensure don't blow out such a bright target . With the DSLR I remember taking 3 different exposure times. LRGB and Ha available on the 314 probably with ED80 Many thanks Mark
  14. Many thanks to all your excellent advice and suggestions, with ZWO colour camera it's not easy to get anything visible, but with gain at 0 and exposure set at around 0.6 ms I can at least see some sun spots so a start I am sure my neighbours wonder what I am doing with a towel over my head but only way to see the screen in an attempt to focus. ... I realise that mono is the way but I will point
  15. hi all just trying to start on solar imaginga nd wondered if anyone knows of a tutorial specific to solar with colour cam ( ZWO ) using Fire capture or sharpcap. a look through google show planetary rather than solar thank Mark
