Very nice indeed. I had some great views of this magnificent object in France this year. Also always a crowd pleaser at outreach events

Thanks Michael, much appreciated.

How visible is it?  The various right-ups I have read imply that it is hard to make out in a small scope and needs a large scope or better yet a long exposure to see it well.  Is that true?

I can't tell with my scope because I have set up my Newtonian with the focuser pointing down to better balance the camera but this means that I can't look through it without expensive post-viewing surgery on my neck.

Cheers

Thanks John.

These are actually old captures that I have been going through and re-processing with my current workflow.  Not many new captures recently because the weather has been bad here for what seems like months with only the occasional good night when the moon is out of course.

Cheers

Mike

M16 is quite an easy target in my 15x70 and even 10x56 bins. At least it is from a dark site where it was 9 degrees higher up in the sky than it is at home. My 80mm F/6 triplet with 31T5 Nagler (15.5x magnification) with UHC filter shows more, but much more detail is captured visually with my Celestron C8 (also with the 31T5 (a.k.a. Panzerfaust ;) ), and UHC filter. The Omega and Lagoon nebulae are visually a bit better, but M16 is also a great visual object

Panzerfaust ?  Is that due to the shape of the 31T5 is similar to the that of the warhead or is it the weight  :)

I suppose I should try harder to find a target that I can look at comfortably - people such as yourself always speak so highly of the joys of observing and with 10" light bucket I should be able to see a fair bit of detail I guess.

This shot used a UHC filter but I've stopped using it for now because I really struggle with colour balance when I use it or my IDAS D1 - but they do definitely help to bring the faint detail out from the light pollution where I live.

A 10" scope should pick out loads of detail in these bright Messier nebulae (and loads more, my humble C8 has notched up in the order of 850 DSOs). A tube rotator should help getting the EP in a more comfortable position

 

"Panzerfaust" does indeed hint at the tapered shape of the massive EP

      The weather has been so bad I have had the time to finish a video on using astro filters with the Nikon Z bodies and Nikon camera lenses. There is a manual alternative to the FTZ allowing 1.25 inch filters to be fitted between camera and F-mount lenses, and for some lenses and end of lens solution make sense. FAstroTZ is described here:

      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?

      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

      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.🤔
