  1. Horsehead HaRgb

    Hi Andy I used http://gifmaker.me/ It's free and what I normally do is use the Snippet tool in W10 to take a quick low res copy of both images and then upload those - although you can upload much larger files to maintain quality etc. David
  2. Horsehead HaRgb

    Excellent demonstration and exceptionally well processed - wish I had time to image this object this year. With these demo's I like to create a GIF to make it easier to see the difference - hope you don't mind me creating one with yours. Looks like it would make a great neon sign for your observatory :-) David
  3. Fish head Nebula IC1795

    Very nice Carole :-)
  4. M42 LHaRHaGB, M44 and NGC 2244

    Here's the GIF I mentioned - looks like I can upload it :-) David
  5. M42 LHaRHaGB, M44 and NGC 2244

    As ever ....processing evolves :-) In my last iteration of the processing of M42 I used RangeMask in PixInsight to focus on the central nebulosity in order to brighten the region. I had used this facility in a number of areas during the processing and it struck me this ran against my preference of doing simply histogram and curves stretches to minimize my "painting" of the data (LocalHistogramEqualisation excepted of course lol!) In this iteration I also limited myself to one saturation boost In short I tried avoid manipulating the data as much as I could to remain close to what I captured - rather than, what can happen with me, "paint" a technicolor monstrosity that while pleasing to the eye, is somewhat too fake for my interest in this hobby. Not content with my opinion on the matter I showed the most recent image process above and the one below to friends for their opinion. To my surprise they preferred the one below - normally people like the snazzy, bright, decal look - something that is really striking in detail - and thankfully, this time they preferred the softer lighter touch I've used on the data in the image below. I notice too that while the image is slightly more noisy it has brought out more of the nebulosity throughout the image. I'm going to produce a GIF (don't think I can post it here) of the three takes on this (I actually like the first iteration I did too - it's a bit bright but looks more natural I think). When you blink between the three this latest version really stands out as a bit more detailed and natural. I've made loads of notes on how I got to this - important to be able to replicate the process, as I no doubt will have to wait a year to try again LOL! David
  6. My first RGB image - M42 HaRGB

    Wow! Excellent results David
  7. The Monkey Head Nebula in Hubble Palette

    I'm seeing green for two reasons, the second being how amazing it looks in this image. I've never understood why green is treated as an artefact to be processed out. I mean, I understand that if you don't the image looks pretty bad - but surely photons are photons and there must be some place for green ones in our images - like this one. However I think I've heard it said there is no green in space.... I remember when I was shooting the Cygnus loop with a QHY8 OSC the result was always green/red where everyone else's examples were blue/red. Some QHY8 owners went with the green/red palette and produced amazing images. I always manipulated the results to get it as close to blue/red as I could - as I was "following the pack" :-) So thanks Steve for encouraging me to see what I can do with green in my next narrow-band image - I won't have the same success you have, for sure, but it will be interesting to try.

  8. FLO Packaging Humor!

    Better than simply an invoice yes ? 😊
  9. Orion Nebula Ha Reprocess

    Enjoyed looking at these - number 2 is my preference 😊
  10. Cone in Ha and HaRGB

    Great work Yves - both are exceptional :-) David
  11. Observatory Gymnastics

    My equipment bent over backwards to get every last image it could of M42 as it set in the West on the 9th of February :-)
  12. FLO Packaging Humor!

    Received my AVX mount counterweight from First Light Optics and did a double take on the labelling! This really is the limit - bad enough the skies never clear and now you get the potential of "bonus" clouds with your equipment LOL! Very funny FLO - made me laugh out loud :-) David
  13. M44 The Beehive Cluster

    Excellent shot :-) I imaged this recently and didn't see any blue stars in mine? I'd be interested to know how you processed this to maintain the blue as I assume I "stretched" it out mine? David
  14. M42 LHaRHaGB, M44 and NGC 2244

    I've finished processing the Rosette that I started above - this is 4.6hrs and I had enough data to make it worth processing now :-) You'll see I've also got rid of the gradient by ditching the flats all together as I hadn't taken any rgb that night to use with the nb filters - DBE in Pixinsight helped a lot :-)
  15. Rosette Nebula in Ha 24/25th

    Nice work - like the Moon in particular - and your set up is very similar to the one I use at star parties (camera and mount) Did you guide these shots? I'm going to try unguided at Kelling with the ASI1600MM at 60sec intervals (although I will take my guide camera and scope :-)) David
