Have you looked at https://telescopius.com/ it is invaluable for planning.
-
The red based bi-colour for me, simply because it has a more of a coloured background, whereas the other backgrounds are a bit thin, and you have maintained the contrast.

Love it, it jumps out at you, you have controlled the contrast perfectly to bring out the interesting detail

Baader OIII filters - A Cautionary Tale
dave_galera replied to Melitastro's topic in Imaging - Deep Sky
https://www.cloudynights.com/topic/634098-halos-around-stars-with-astronomik-oiii-6nm-filter/ Might be helpful as it does refer to the same camera -
Baader OIII filters - A Cautionary Tale
dave_galera replied to Melitastro's topic in Imaging - Deep Sky
There are quite a few reports that imagers getting halos with Astronomik filters seem to be camera related, and there are a lot of imagers who don't get any halos with these filters, and like I commented above I don't get halos with 2" Baader filter/Atik camera combination -
Baader OIII filters - A Cautionary Tale
dave_galera replied to Melitastro's topic in Imaging - Deep Sky
So reading this thread got me worried as I also have a Baader OIII filter. Just checked 5 different sets of OIII subs with at least one very bright star in the frame, and .......... I haven't got any halos around any bright star, slight halation yes but not definite halos, but mine are the 2" version not the 1.25", so maybe this makes a difference. -
I have the same filter wheel and never had a problem with. Suggest you take the cover off and make the motor spindle is in contact with the rubber edge on the filter carrier. Another thought are the position sensing holes clear of dust and dirt?

Brilliant image, beautifully captured, very very nice

That is a serious mosaic....well done, beautiful detail

Advice on suitable/ideal CCD for an FSQ106
dave_galera replied to MakeItSo's topic in Imaging - Deep Sky
Consider the Atik 383L+ with future proof 2" filters, and if I was you I would get a camera that is a 16bit -
Brilliant and very colourful

+1 for talking to Ian King....he sorted me out..... -
Yep looking very good now, but there is a bit of noise there....try MureDenoise as its absolutely fantastic at removing noise before you combine the linear masters

That is coming on very nicely, the data seems very good

You could try using MureDenoise on your Ha, SII and OII masters straight after integration.......this is a fantastic script that gets rid of just about all the noise, but the images have to be linear and have absolutely nothing done to them for it to work correctly

I am sorry but I just don't like the green and the reddish background, what has happened to the normal SHO colours?

Very clear detail, well captured
-
Here you go: 1. Open the 'starless' image and the 'original' into PI and create an image of the 'stars' using PixelMath 'original' - 'starless' (it will be black with white stars) 2. Save the image of the 'stars' 3. Process 'starless' image as required and save as 'processedstarless' 4. Create new composite image using PixelMath as 'processedstarless' + 'stars' If you need any more explanation get back to me

Beautiful image, well captured and worth the integration time. I use StarNet++ on these type of images to remove the stars, then work on the resulting starless image to bring out details in nebulosity etc.......when finished add the stars back in which is dead easy to do in PI using PixelMath. This way processing the background detail does not effect the stars.
-
I definitely like the second image more in keeping with SHO, well done
-
Nice image you have captured..........IMHO its not cheating as the only alternative would be to pack a suitcase and take your telescope out there which would be rather expensive. Using iTelescope, as I also do from Siding Springs, gives you the opportunity to image targets that you couldn't normally do....you still have to set the telescope up with exposure time RA and DEC, pick the correct time to image and then process the subs.......

And something a little different, filaments of the NGC6960 Western Veil Nebula in OIII only. The image was captured from iTelescopes remote location in New Mexico with telescope T21, image captured with three hours integration, processed starless with StarNet++, PI and PS, and coloured in the blue-green light of the OIII emission. Thanks to John Ebersole for the inspiration to take this image.
-
Beautiful details and slightly different colouring to normal SHO but I think I prefere it....well done
-
Both brilliant images.....extremely well handled with regards to noise, contrast and colour balance, I do like good narrowband images, and the long integration times have paid off.
