Horsehead nebula from SE London
« on: 17:39:57, 01 January, 2018 »
Got myself outside for the two clear nights on 27/28th December, albeit sub zeros temperatures.  Thanks to a "heads up"  in the forecast. 

Had to wait until the Moon went down on 27th in order to get the RGB and even then the data was still a bit iffy and required quite a bit of processing due to my LP location. Spent the rest of the time doing Ha (Luminance was unusable even after the Moon had gone down). Had to stop when the target disappeared behind the trees in the West around 2.30am.

Ha 21 x 900secs + 10 x 600secs - Almost 7 hours
RGB 32 x 150 binned total 1hour 20mins
Grand total 8 1/4 hours
SW130PDS & Atik460EX, HEQ5

Thats a cracker Carole. Something a bit odd down the left hand side that could do with cropping.

Great stuff Carole - took some perseverance by the sounds of it but well worth it.

Thanks Chris and Annie.

Yes, it hasn't shown on any other places I have posted it as it doesn't come out as large elsewhere, so I and no-one else had noticed it before.  Needs cropping off.

Posting the Proxy link from SGL is a little bit of an odd way to link to an Astrobin image :-)

Works just fine every-where else I post, and if I try to upload a file to UKAI it only like small sizes so I have to create one specially for UKAI much smaller than I need anywhere else.

What do you suggest?

I wasn't trying to be awkward but there are two choices for you.

1) create a smaller sized jpg (1000 x 700) under 500kb to post here. This is what I tend to do. A full res jpg goes on Flikr and the smaller one goes here.

2) create a DIRECT link to the Astrobin file on here.

Your post seems to be a complete copy and paste of your post on SGL INCLUDING the SGL meta data for the image so what ends up on here is a link to the SGL Proxy of the image and not a link to the actual Astrobin image itself i.e. your image link is

https://stargazerslounge.com/applications/core/interface/imageproxy/imageproxy.php?img=https://cdn.astrobin.com/thumbs/czVJ8wRug1HQ_1824x0_vEFfvLwC.jpg&key=e48e722c2cdd09be472b46bf278fa43722413a9ac137932c04e06056974b3c29

If you click on that link you can see it takes you to the SGL proxy image which is 1824 x 1389 and that is what come through to UKAI NOT the Astrobin image.

Hope that makes some sense. Though I am not an expert I suspect that every time someone looks at your image on UKAI, it is being pulled from SGL which in turn is being pulled from Astrobin. Now while we are happy to have SGL proxy images posted on here, doing so probably breaks a whole load of their terms and conditions plus something in the code gets lost between SGL and here. I'm pretty surprised it actually works at all!

Thanks Roger.  The headups wasn't on UKAI.

OK Chris, I see what you mean, I just thought when I had previously linked from Astrobin say onto SGL it would come up as the same Astrobin link when I tried to post it elsewhere.

Tried again with a direct link from Astrobin (below) and it comes up exactly the same size. 
I am not going to mess about with compressing my files into Jpegs. So I will just post a link to the file on Astrobin next time, though I do hate it when other people do that, but I don't see why it comes out a normal size on at least 3 other forums I post it on.   

I don't recall having this problem with linked images on UKAI until this last year, I have always done it this way, it must be something  to do with a website upgrade.

Believe me its complicated and comes under the general banner of "You can please some of the people some of the time.....".

What you are seeing on UKAI is the "normal" size for your Astrobin image because we don't downsize images as posted i.e. what you are seeing is the size of that chosen image size on Astrobin.  The at least 3 other forums you post on probably do downsize your images to fit with their posted image size limits. The Image Proxy from SGL is actually making a local copy of your Astrobin Image and then resizing it for SGL forum i.e. the SGL Forum software is "messing" with your image without you knowing what its doing. Personally, I would much rather do my own resizing so I can see the end result. I find big images benefit from even integer downsampling (software binning) as simple resizing involves an interpolation, even integer downsampling doesn't. In the past we had that resizing turned on but then got a bit (aka quite a lot) of moaning because the forum resizing algorithm is a bit basic and downgrades image quality.

Astrobin provide a Sharing link that will generate code for posting on here that provides a thumbnail which when clicked on links to the full image. Not ideal but I see it used a lot on other Forums due to the image posting limited they impose.

Hope that explains a bit and shows that it is complicated!

Got it, didn't know that was there.  Thanks, something new I have learnt.
