  1. Thanks for the insight guys! At the minute I will have to stick with ps as my laptop is too old/slow to cope with a lot of the other processing software. I've tried startools, and every process takes forever on my laptop, and pixinsight won't run on my laptop at all! I do have the astro flat pro plugin on photoshop, which I find does work to a point. 

    But seeing as there's a month trial for astro poxel, I will definitely try it, and see how it runs on my laptop.

    Agree. I wouldn't go any contrastier than that, I have a fatal weakness myself for toppling into "garish".

    You didn't say what you were using for processing but I'll make my by-now-standard pitch for Astro Pixel Processor here. It is AMAZEBALLS at removing gradients and light pollution, and you needn't have a physics PhD to use it.

    I currently use photoshop, though I am tempted to move to something more astro specialised once my years subscription comes to an end in few months. Might have a look at astro pixel processor 

  3. Had another go at processing this data, Didn't do anything majorly different, just got a bit more aggressive with the stretching and saturation. I'm still struggling with noise on the left hand side of my images, due to a street lamp which shines from the west.😒 I'm sure it's possible to process this out of the image, but I'm still very much a novice in that regard. Regardless, I think I prefer this version.

    Forgot that - I just chopped the cigarette lighter end off and swapped to the right size connector for the DSD. You can buy them there the wires screw in so no soldering required!

    Ok, that's definitely an option. Do you mean something like this...

    I have a DSD power hub and had the same q. I've been using https://www.harrisontelescopes.co.uk/acatalog/power-supply-10a.html#SID=1667 for a year now.

    No idea if it's better than the cheaper ones on eBay, but I've had it for over a year and it's still working.

    Thank you, exactly what I was looking for! It's worth the extra £10 over the ebay option for the peace of mind of knowing it works!

  6. I've recently ordered a DC Hub from Deep Sky Dad like the one from the link below:

    https://shop.deepskydad.com/product/dc-hub-2/

    It doesn't come with a power supply, so I need to order a 12V DC supply which can supply at least 8A, which I can then connect to the mains. I'm not overly keen on spending £60 on the pegasus astro PSU, and there are some available on ebay/amazon for about £20, but not sure if these would be any good. 

    Any recommendations would be welcome!

    Yes banding can be an issue...it's also been pretty warm recently which won't be helping.

    I know it's a bit old now but I followed the video from Astrobackyard

     

    Thanks for the link! Had another go at processing the data using this tutorial.  Still far from perfect, seems much better than my original

    I think this was taken with my general light pollution filter... interesting that you're only using 1.25 doesn't that restrict the FOV? I guess it depends where in the imaging train it is.

    To be honest, it does cause some vignetting on the corners and sides, but some flats seems to deal with this quite well. But I'm not sure if the troubles I'm having with the processing is partly due to this filter and the vignetting not being corrected properly. I didn't have this many issues with processing before, but other factors might also have a part to play(warm weather).

    I am tempted to invest in a 2ich L-enhance though!

    Thanks for this, I will give this a go later on. Out of interest, did you use a filter for your image? 

    I have recently started using an 1.25inch UHC filter which I clip on the front of the camera via an adapter. I'm not sure how much (if at all), this has improved my imaging.

    Hi

    Nice shot.

    You've thrown away a lot of the nice darker bits. Leave room for them. There's almost certainly a lot more to be had:)

    Most astro software will shift it. The cleanest I've seen is StarTools' Wipe. Siril also does a good job and has the advantage of removing the banding on each frame before stacking using its sequence thingy.

    To minimise it, lose the dark frames and give a bigger dither between each frame.

    Cheers and HTH

    Hi, I think I've lost a lot of detail trying to control the banding!! I'm dithering about 10 pixels (on the guidescope) between each frame at the minute, I'm assuming that should be enough?

    Thanks for the tips regarding software, I might try stacking in Siril to see if that helps

    Nice shot.

    5 hours is quite a bit of data to work with, how have you processed it?

    For the 600d what iso are you using? Don't bother with the ddark. Are you dithering between shots?

    969595871_Heart4hours.png.da747763e09b4ab16e27db4276ef9b83.png

    This is about 4 hours of data using the same camera.

    Hi,

    Yes, I dithered between each frame, and shot at ISO 800. I haven't bothered with darks before, but gave them a go this time to try to reduce the banding. I think there's something in my setup which is causing this which I can't pinpoint at the minute. 

    Processing - I stacked in DSS, and all the post processing done in Photoshop. My basic workflow is: Curves stretch, colour balancing/background processing with Astroflat pro, and some tweaks in Camera raw filter to reduce noise etc. Yours looks much better than mine

  12. Been working on this image of the Heart Nebula over the last couple of weeks. For some reason, the banding on my 600d was really bad, maybe because of the warm(ish) weather, so processing with my very limited skills was a challenge. 

    The image consist of about 5 hours of 3 minutes subs. Calibrated with flats, bias and darks (which I don't usually use, but did this time to try to control the banding). 

    Any constructive criticism welcome! Also any tips on how to handle the banding with the 600d would be appreciated!

  13. I came across an app called Telescope.touch on an astroberry group on facebook. I'm very much a Linux novice, but I believe it's an app to control your imaging session via indi(not specific to astroberry). 

    I've had a play around with the standard (free) version of the app, and everything seems to work, although I haven't had the courage to risk a rare imaging session using it yet. From what I can see, it should control everything including mount, camera, guiding, focuser etc.

    The full version is £10. Does anyone have experience with this app? Is it worth the extra outlay to get the full version.

    Lovely shot.

    For targets like these with the blue-green stuff, we use a UHC filter. They're only cheap items and bring the nebula to the fore. Keep your existing frames to restore star colour.

    600d banding: dither and take more frames to even the background.

    Cheers well done and HTH

     

    Thanks😊

    I actually did dither for this image, I'll try a larger and for frequent dither next time to see if this helps.

    I have also just got a new uhc filter, so I will try to add some data with the filter when I can. How would I go about combining the data?

    Thanks for the advice👍

  15. My first attempt of the Western Veil nebula, taken over the last couple of nights. Total integration time was about 3hr 20 min, taking 5 minute subs, and I took about 20 flats and bias frames. The equipment I used was my HEQ5, Evostar 80ED and modded Canon 600d.

    Not going to win any awards, very noisy with some banding also. Also not convinced my processing skills is up to scratch, but relatively happy with the final result as I'm only starting out.

    Any advice on how to improve from here is welcome, I'm guessing the recent hot weather doesn't help with the noise levels of the 600d!
