Thanks!, love the image. I use Sharpcap and a T shirt for flats with an ipad for the white screen, maybe i need to change this? i'll look into better ways to do my flats

I also thought it was light pollution but as I started imaging after the flip I couldn't work out why it was all around the image, I will trial one of the gradient removers for ps, looks like the way to go. Thanks.

I just don't understand why it hasn't been this bad before? very impressed with your processing though, is there some software i can use in PS to remove the gradient to that level?

Yes, i even re-did them but it may be that i'm doing them wrong?

Hi, I just did a quick stretch to show the issue

I was using Skywatcher evostar 80ED, an ASI553MC Pro for imaging and a HEQ5 Mount. The subs were taken from 11pm to 3am this morning. After stretching the image i see blue stars all around the the outside of the image and i can't balance the colour with the centre of the image

Hi all, I have been imaging recently without issue but i'm very new to this, i went for the Markarians chain last night but it seems to have issues all around the image?, I'm not sure whether it's light pollution or poor Darks/Flats. I used a UV/IR Filter. Any help would be great just so i can find out what it is to make sure it doesn't happen again as this was a total of 4 hours imaging! Thanks. 1.TIF

Thanks for this, I am learning a lot Thanks to you, much appreciated!

Thanks for this, i think i have corrected the issue thanks to Thanks for this, i think i have corrected the issue thanks to Vlaiv's "save as" settings. I have applied Flats and Darks but there i a huge dust spot which i am going to clean before i next image!

Thanks for this, i now think i have fixed the issue, i have uploaded a new stack if you want to take a look, if not then thanks for your help, much appreciated!

I have added flats and dark flats but there is a huge dust spot that you are refering too, i will be cleaning before i image again

Thanks for this info, using your "Save as" settings has definately re-instated my colours, there does seem to be more green in my images but isn't that normal in these cameras? NGC4565- 28 x 5 min,101g.TIF

Thanks! That's a lot better than I have achieved in PS, there just doesn't seem to be enough colour in any of my images? Frustrating!!

Hi again, i have tried all of the above but i'm still not getting colour in my images? i have attached a dss stack to show the colour channels, shouldn't they be over to the left?

Thankyou, you just saved me from eternal frustration!

Thanks for your speedy response, i'm very new to this so please bear this in mind with my answers. I use DSS and i just put the stacked image straight into Photoshop, i then convert it to 16bit, level the colours, stretch using curves and levels until i'm happy with the image.

Hi All, I'm new to Astrophotography, i'm just trying to find my feet. Please could someone explain why my colour images coming out in black and white with very little colour, i have the following setup and use Photoshop to stretch the image. Thanks. HEQ5 Pro UV/IR Filter ASI533MC Pro Evostar 80ED 20 x 5Min Exposures at gain 101 on attached example 5min.tif

Love the picture, that's exactly the type of image i want to be able to get, i'll invest in the uv/ir blocker, i'm in Bortle 5 so i get a descent view, also our street lights go off at 1am so i'll be doing quite a lot of early morning imaging! I'll be interested to see how you get on with the blocker if you can let me know. Thanks.

Thanks for that, would there be any filters that you can recommend for imagery? for planets, DSO's?

Hi all, I'm looking for some advice as i have only been observing until now, i'm awaiting a delivery of a HEQ5 Pro to get in to imaging, this will be a while as no-one has any stock, i have a 10" Dobsonian now and i have bought an ASI533MC Pro so my question is if i take short exposures of the Moon to star practicing imaging, will i need to use any special filters as i know the ASI is not a regular camera and i don't want to damage the sensor. Thanks.

I'm in the UK, thanks for this

Thanks all, great advice and lots of helpful advice. Roll on tonight! 😀

Hi all, i recently purchased my first telescope, I have a 10" Dob, I'm in a bortle 5 area, I want to see Dso's ,I have lined up my finder to my scope, i can easily find m42, however after 10+ hours of viewing, the orion nebula is still the only nebula i can find! I have a 2" ep which I use for finding, I also have a light pollution filter attached, I use stellarium for locating nebulas. Any idea what I could be doing wrong? I have been trying to view the jellyfish nebula as it's easy to find but I only see stars? Any help will be much appreciated. Thanks.
