I can finally add something I'm proud of using this scope, I'm still very new to all this though.

Great image, my only suggestion would be to nudge the green channel down slightly as i think its a little bright relative to red and blue.

Here's a question... in RGB the OIII part of the Rosette looks a sort of washed-out red compared to the Ha parts.

Is there a trick with selective colour or similar I could use to turn it blue with being overly artificial?

Not sure which software you use,

in Pix, you can run Color Mask script to generate Mask for each color and brighten the part for OIII.

In this case, I was actually made to push it very hard... as most of my OIII subs went to the bin ;(

M42 Orion Nebula

Frames: 41×180″ & 20x30"

20 Darks/Flats/Bias

In my personal opinion, I do prefer the core being blown out as HDR MultiscaleTransform just wasn't dealing with it well and it preserves contrast.

Overall it took me about 20 hours from setting up and taking images, to doing iterations of this in PixInsight and finishing. 

Once I get a modded DSLR, I'll be sure to add some Ha data to this.

Any CC or comments are appreciated :)

A touch of lurgy at the moment has given me an opportunity to catch up on some imaging processing. The cone was the trickier of this pair- it’s much less bright and because there’s lots of gas around it, finding some background to calibrate on was not easy. Also, in my efforts to strip light pollution (both moon and LED) from the RGB subs I’ve removed any Oiii signal which I know is present somewhere in this! California was easier as it has higher surface brightness.


Cone:
14/2/19: Ha – 14x 10 min subs (yes- my wife is very understanding)
21/2/19: RGB – 40x 2.5mins subs


California:
14/2/19: Ha – 14x 10 mins subs
9/1/19: RGB – 12x 5 mins subs

Looking for the last upgrade.


Baader ClickClock looks luring...

Has anyone tried it with SW CC which is also 0.9 reducer and ASi1600MM?

That lock is 30mm, - I afraid my ASi  will not get in focus with it while focuser is Fully IN.

I can 100% confirm to you that you will not have sufficient back-focus to accommodate the clicklock I tried it and it did not even work with a Baader MPCC MKIII and that does not change the focus position like the SW CC does. By moving the primary mirror an uncomfortable distance up the tube I was able to just...and I mean just reach focus with my LRGB filters but I was not able to reach focus with my thicker astrodon narrowband filters. I was not comfortable with leaving the primary hanging like that as I did not believe that it would hold colimation. 

You could try pairing it with a Explore Scientific Coma corrector as that moves the focus out 3.5cm....but that's an expensive game to play.

Thanks a lot for confirmation Adam!
It looks like my upgrades are done for now.... :)

Great, thanks.

On transparent at the moment but may give that a go when I'm on black again.

      Selling a nice portable wide telescope with great glass and a great field of view
      I have two telescopes and I'm using the 80ED more currently and so this Telescope just isn't getting used anymore
      It has a longer dovetail (originally from the 80ED) so declination balance can be reached.
      Great performer for the price
      Collection only as P&P is like £40 (Northamptonshire - UK)
      Selling to fund a scope or mount upgrade.🤔

      Skywatcher 80 ED DS-Pro outfit including matched flattener and motor focus. Now only £350
      This kit gives you a great introduction to astronomy and imaging, which is why it's so popular.  You can see details over at FLO but there is:
      80 ED Ds-Pro OTA (Objective Lens Diameter: 80mm, Telescope Focal Length: 600mm,  f/7.5)
      SW Eyepiece (2"): 28mm
      2”/50.8mm Di-Electric Star Diagonal
      9x50 Finderscope
      Dual-Speed 11:1 2” Crayford Focuser (Backlash-Free)
      Supplied with Tube Rings & Mounting Plate - please note there is a longer black vixen type dovetail fitted, not the fancy new green short one you will see on the FLO site
      SW motor focus and fitting kit - I've never used this, hence it's not fitted (more details over on FLO)
      Dedicated SW 0.85x reducer/flattener (see FLO for more details)
      Aluminium Carrying / Shipping Case
       
      The RRP is over £720, so grab a bargain while you can.

      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 to everyone, I used to do some astrophotography in the past with a Celestron AVX and DSLR but after few month had to give up for several reasons, including light pollution (I'm living in zone 3 east London), and also working shifts. Now I want to start again, and this time more serious. I've been searching around for a couple of months to choose all the gear and I'm quite happy with the list so far although it's a bit over the price I planned at first.
       I will get an William optics Z73 with his 50mm guide scope, a flattener/reducer 0.8, light pollution filter IDAS D2 and as camera I will use a Canon 600D modded and I will buy a ZWO 183MC Pro, after so much research, I'm very happy with the scale and framing I will get with this combo, but I'm starting to get confused with the mount.
      My first idea was to go for an HEQ5 Pro, as my previous experience with the AVX has been awful, then I realized that the FLO, sells that mount with belt modification and also some cleaning and tuning if required, I heard that it's a big improvement over the stock one and the price it's ok, but another important factor for me it's portability. Unfortunately, my garden doesn't allow me to do much so I will need to carry around on trolley, for a km walk, I'm a strong person and been doing plenty of time with the AVX, so my confusion came recently when the iOptron mounts entered my radar. I start comparing the heq5 pro with belt, with the iOptron cem25EC and the CEM40 without encoders, and I'm so unsure of which to buy, the cem25 seem to be the equivalent of heq5 at least speaking of payload, but in some threads I read people saying it's a bit fragile so kind of remove it from the equation although the weight it's interesting for my situation, then the cem40, seem to be quite similar on weight to the heq5 but with higher payload and that's interesting too as I will buy a C11 at some point.
      Now it will all come down to the accuracy of tracking I guess, how the heq5 and cem40 would compare on tracking and guiding? If the cem40 it's better, I would probably go with that since it holds more and would last longer as I don't plan to get anything bigger than a C11, but if the skywatcher it's better, I could decide to go for that, and when I move to a place with better garden then get a second mount with higher payload.
      Apologise for the long post and my english.
      Kind Regards,
      Giovanni.
