My first image of M76 A bit rushed as clear nights are a rarity now

30x120s Bin 2 Luminance ,SW 102 , ZWO 183MM Pro , OVL field flattener ,guided , processed in Gimp

Took some Ha as well but poor results for some reason

Seems an Oiii filter may have brought out some more detail


i know its not great but just chuffed to have imaged it

It will stand out more when you get some coloured narrowband in there.   Looks like the 183mm is a sensitive beast, what temperature below ambient do you run it  ??

I imaged this for the first time this year as well.   I trusted the accuracy of the mount to get me locked on, and there it was hiding behind the low level noise.  Such a satisfying feeling, I can empathise with you being chuffed.  Makes you feel for one short moment that you have this hobby sorted.......

It was set to -10C using the latest APT which has improved support for ZWO cameras now. To be honest it was so cold i could have done without it !!

I agree about the feeling but i rush things now due to the weather.  i got runtime errors using CDC and eqmod and nearly gave up

if you would kindly post your image as well

Cheers Mike

Wow something to aim for ! Well done

i will have to invest in a complete HST set of filters. M31 is also on my list to do well with my modified 450D though i may try a 

mosaic image  with my 183..... a zwo dual narrowband filter looks interesting

How do you find imaging with a newt ? i have looked at getting a 150pds

The newt is a real photon grabber.    It is heavy and will take out low flying aircraft as it slews around the garden but it will put down an image of a faint DSO within  a 30 second sub, whereas my 80mm refractor  needs a good deal longer.   Collimation is not tricky once you set up a routine and have the right tools handy.  The main issue is the sheer weight of it.   Even on an EQ6 it does need a bit of TLC to get all the rotating axes in balance and the motors not screaming !!!  especially if you have guiders, mini-pc's and usb hubs hanging off it as well.

The 150pds is a great scope to get you started with reflectors.   There are some quite remarkable pictures taken with this scope.    Go on to  astrobin.com   and do a search of what people have done.    I sure there will be an imager out there who has got a 183mm with the 150 PDS. 

I look forward to seeing your results.

      These are my last images of 2019 taken with my ED72 and 183mm pro to be replaced by a 533pro
      These targets are not easy due to location trees etc except M1 , there was a bright moon as well so are all lucky shots
      but at last i have taken them warts and all
      Anyway a merry Christmas to you all and a Happy new year

      This has been a bit of a project.  Last year I worked out that my 200mm Canon F2.8 lens and ASI1600 would frame the whole of the Veil complex quite nicely.  I captured Ha and OIII data for the east and west nebulae with a Tak FSQ 106 and added this into the widefield image.  Although the Tak data had to be shrunk down it did add a bit of extra resolution where it was needed.  
      The difficulty for me has been the processing.  I have found it really difficult to tease out the faint wisps of detail and have tried the usual routines of micro contrast adjustments using curves along with Scott Rosen's Screen blend/mask inversion method but the results weren't great owing to the close proximity of faint and bright nebulosity.  I'd heard about the PI process tool for removing stars, Starnet, so loaded this and had a rare foray into PI.  This proved very helpful.  It was a luminence created from Ha and OIII using the 200mm lens with the Tak data mixed in.  Then the starless layer was added in PS with the screen blend mode at 50% opacity.  The nebulosity detail was so well preserved I didn't need a mask.  After blending I reduced the stars a bit more using the starless layer again and darken as the blend at 50%.  I should really unleash some of the stars to add a bit of "punch" but I've wrestled with this data enough for now!  I plan to use it further as I look deeper into the Gorgon that is PixInsight!
      Telescope: Tak 106 for E and W veils.  Canon 200mmL lens
      Camera: ZWO ASI 1600 pro mono cmos, Gain 150, offset 50
      Filters: Baader 7nm OIII and Ha
      E+W Veil 10x30 mins each channel for each nebula.  Whole complex 50x5mins for each channel
      Captured with SGP, calibrated, aligned and combined with PI, processed mainly with PS but PI for Starnet.  Ha mapped to red and OIII to both blue and green
