M76

[mikemabel]

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

Here we go..

HST image...   15x 1mins on each Ha, S2 and O3.   250mm Quattro newt  with Atik 414 mono.

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 

 

[Craney]

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.
