    Wonderful image, I love the colour rendition.  I'm about to rework my version of the Trunk based on processing knowledge people have given me here recently.  So I'm looking forward to seeing the full details on your website.

    Update:  Just had a detailed look at your website (my first time, very impressive, lots of information, beautifully presented).  Your images are really outstanding and your site is a pleasure to browse.  I'm in awe.

    Thanks so much Robin....glad you found the site interesting. In the early days, putting the site together was a lot of work.....now just adding the images as they come only takes an hour maybe.....as I put the info in and update links. Weebly is a free site hosting facility.....it was a great project for me....taking plenty of time but not costing anything.

    (I have one page that still needs updating re my present camera. Note to self:...."get it done next week"! )

    Great image.  I bet you have some awesome skies in Spain. 

    Carole 

    Hi Carole, yes there are some great skies in Spain.....BUT not where I am unfortunately. When I moved to Spain I was not into astro-photography at the time. If I was...I would not have bought near the coast and most especially not along the southeast coast. I am plagued with both high humidity and bad light pollution......AND....no chance that my wife will consider a move just so that I can get better night skies. What to do.....I just make the most of it when I can and stick (for the most part) to narrow band imaging.

  3. Normally my NB images take me a week or quite often more to complete, start to finish. This is one of the fastet I have ever done - started Wednesday night and processing completed on Friday afternoon. Two x  full night's data did the trick nicely! A total of 11 hours & 40 mins. (Full info & higher resolution on my web site).

  4. Well done Richard - looking good 👍. Good to know that the filter is now "at work". Interesting for some of us 'old school' guys  to see the result when using this type of filter.........such short overall exposure too!

    What scope and camera set up was you using

    Hi Paul.....thanks for commenting.

    This is with the Tak FSQ130ED and FLI ML16200 camera. Very shortly, I am going to fire up PixInsight again and this time, I will try adding the NB data to the RGB image.......if it makes an interesting change and is OK, I will post that also. While out walking the dog just now....I was thinking about it and wondering if it would be better or worse :icon_scratch:

  6. Originally planned as an SHO image - but there was little or no OIII in this area. Ended up as a bi-colour (HSS=RGB) with RGB imported into the stars only. IC 1311 is the small open star cluster in the top right quadrant. Full details on my web site.

  7. Thanks Martyn. No worries....I make my images for Pixel Peepers 🤣.......I am afraid I am one myself!

     

     

    If you do not know it already....you must click on 'Download full size' to actually see the full res image in telescopius.....then when you have the  little + sign....you can click on the image again to get it.....the one I put up is 4470 x 3600.

  8. I could not upload this image earlier today - not sure if it will go now until I hit the "Submit" button.

    It is related to my prior posted image - which is a crop from this one. I could not use the same colour palette on this full one as Crescent came out blue....whereas Blue/Green is more in keeping with the Hubble Palette end colour.

    It is nice to look at this one in high resolution....you can find the largest image on Telescopius....uploaded today, so should not be too hard to find.

    I've come to expect a lot when I click on one of your threads

    ......just kiddin'....thank you so much for saying that Ian.

  10. Hi Martyn, thanks for the comments. My initial hesitation with the full image was due to the Hubble Palette mapping. I am used to seeing the Crescent Nebula in Red/Salmon colours so when it comes out in Green & Blue in the final full image, it really is off-putting. But, since Ha is mapped to green and OIII mapped to blue....then one should not expect anything different!

    When I did the crop above, I was able to play with the colours to make that section look more pleasing to the eye (for me anyway). When I did that, The Crescent (in the full image - that you have not seen yet) comes out blue.....and I could not go with that. So....bottom line: the above image is fine as is....no more exposure time needed.The full image will show this area more green (again, overall ok without needing more data). This more green full image just took me some time to get used to ... but I will put t up on my website later and leave a link (and thumbnail version here)....to explain better.

  11. This is a crop from an image I am presently working on. Just cannot decide (for the full image) if I need extra data or not.  It is the overall colour though that needs attention.

    For this area though....the data looks fine (I think) : Ha-36 subs, SII-32 Subs & OIII-31 Subs (all 10 minutes).

  12. There really can be no answer from us looking at two JPEGs. If you are doing long subs in excellent conditions - then, as you see, a bunch of them will not pull out  too much more detail. You will get a better SNR with the stack but if there is not too much noise in the single sub.....well there is only so much that stacking will do with that too. Only to be expected I think........but each target will be different.

    I have often planned many hours of subs on targets only to stop at half my planned amount - simply because I knew many more hours would not make a huge difference. Now, (you may have noticed from my posts), I test what I have from time to time....after 3 hours of data; after 5 hours of data.....whenever it is convenient to have a look (and not at any set points). Sometimes it is just not worth getting  say 10 + 10 + 10 hours of SHO.....but you may find your time is better spent with e.g 8 hours Ha + 12 hours SII + 10 hours OIII.....or whatever....depending on the signal from the object you are shooting.

    I don't necessarily agree that the single sub here is clearer and deeper. You say you have just done STF. The stacked image I would imagine will lend itself better able to be processed than the single sub....I am sure the fine detail is there to be drawn out. Just perhaps it is a fact....that you did not need 10 hours of subs to get it!

    Have fun and enjoy the journey. Perhaps it will be clear again for me tonight (I have 3 different images needing more data)....but in the meantime I have lots of work to do in the garden!
