My First Astrophoto Period!!!!

Recommended Posts

HEY its about time eh!!!! my first astrophoto with a dedicated cam using all the bells and whistles like iCap and Registax.

 Programs that are still alien mumbo jumbo to me, but after eating a whole bunch of youtube videos and a bunch more trial and error, I finally pumped out this abomination, or so it must seem to you Pro's lol

I had a very vague idea of how to set up proper parameters in iCap for lunar imaging but I tried several settings and used youtube also, regarding wavelets, I basically dragged sliders all over the place

and watched changes occur. There is much to learn about post work in iCap, but i'll give it the old college try lol, my sole reason for posting is for feedback, this is where you Pro's shine, oh do I need 

feedback. 

Anyway, it is my first astrophoto so no matter how much better it can be, well, it will do for now and I say that with a bit of swag because hey! at least I see craters there lol.

Exposure time.....no clue!

Number of frames....a whole bunch

Attempts.....way too many!

Wavelet values.....all over the place

De noising....didn't work at all I think

Codec...Y800

Resolution...12 something by ??? forgot

The conditions were horrid, a mak is not an imaging scope as I have learned the hard way, F1800 not good, I will definitely be looking at a much shorter FL scope,

Far too tight an image, I would need a 50 shot mosaic for full moon, or a focal reducer which I'm not sure anyone makes for my Mak.

Nothing wrong with a Mak for lunar or planetary imaging. They're not used as often for DSO imaging because the long focal length is challenging for long exposures. Great first image!

You'll find that the more frames you stack, the less noisy the image becomes. With wavelets in Registax you will find that Layer 1 is the smallest layer and the wavelet effect becomes coarser of you go up the layers. You'll probably want to use Wavelet layers 1-3.

Nice image.

I am very new to all this as well and you could say it is a challenging pastime and at times frustrating. When I first started a few months ago I looked at lots of images on SGL and thought they were nice images. Now I have had a bit of a go myself I think they are wonderful, incredible images and that they did not come easily.

It's a great hobby / obsession made a lot easier with help and advise from others on this forum and hope one day to produce images that I am proud of.

      I found this setup in internet and make me think, with AZEQ6 GT and 2 scopes, different weights and size, without counterweight in AZ mode! 
      - I can put a MAK100mm 3kg +- and a OO VX10l  12kg +- without counterweight?
       
      Does anyone have this setup mount and already used without counterweight with two telescopes of different weights? Is it really necessary to have a balance using in AZ mode?
      The problem to centralize the object with both scopes is true? With the SW AZEQ6 GT?
      Follow the images
      a TSA-120 with 6.5 kg i think and the other with 22kg i forgot the brand hehe you can help me?

      £180
      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 150/1200 f8 planetary Newtonian.
      Bought this originally intending to set up a planetary rig but circumstances call for sale.
      Will come with eyepieces and a collimation eyepiece. Not used by myself and has seen very little use. Mirrors in good condition
      Collection only
      £50

      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.
      Collection from Nottingham, or DHL for £20 (within UK)

      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!
