  1. Hi everyone 

     

    last night I took 30x30sec exposures. 
     

    i was hoping to capture the horsehead nebula and the flame nebula. 
     

    ive tried to edit in siril but I keep getting these huge grey marks on the photo. Any advice 

     

    this is after background removal and green removal

  2. Hi all

     

    this evening I managed to record Jupiter for about 10 minutes 10x1min videos 

     

    i put the videos in lynkeos to choose the best frames but every single one is blurred. 
     

    My setup canon 700d Sky-Watcher explorer 200p 

     

    no Barlow lens 

     

    Whilst I can achieve focus without the Barlow I believe it may have been a mistake on this occasion. 
     

    it looked clear in the live view but on a computer when I zoom in it’s just a fuzz ball. 
     

    i don’t get it.

    Grab yourself a shutter release cable, that should deal with the wobble. don't bother with a Barlow, all that will do is increase magnification and crop the image. The Orion nebula will fill most of your frame there if you have enough exposure. Focus is only slightly off, to my eyes at least but a bahtinov mask will help you sort that out.

    A tracking mount will, ok I am going to be honest based on my experience here, a tracking mount will drive you insane for a good few sessions until you get to grips with it. Once you have nailed down setting it up and aligning it it opens the door to the incredible images you can see on this board.

    Orion is a bit of a special case because its so very bright and only needs "short" exposures. If you want to shoot stuff that requires exposures over 30 seconds, which is pretty much everything else in the sky, you will need to be tracking. Once you get over 60 seconds you also want to be looking at guided but don't worry about that for now.

    Personally I would skip the mount upgrade path, i.e. adding the tracking motors, and head straight for something like the EQ5 SynScan mount.  

    As for stacking, yes its a bit of a mystery to start with. My route through the various options started with Deep Sky Stacker, which is free and perfectly serviceable, then onto Astro Pixel Processor which isn't free for stacking, and PixInsight for post processing which also isn't free to quite an amazing degree. 

    During daylight you can shoot a set of calibration files and reprocess your existing image, so if you are at a loose end today you can try that.  I cannot stress enough how important the calibration files are, that's the Darks, Flats, DarkFlats etc. each set does something very specific to remove noise from your image and increase Signal to Noise ratio.

    Here's my first Orion, 2nd January 2017, the nebula is one of the out of focus blobs, the slightly pinker one. :) Thats 16 sec at F1.4 ISO 400 on a Nikon D800E, 85mm lens.

    Thank you! Ordered a bhav mask. Hopefully it will help.

    It looks like just star trails, possible wobble, for static camera exposures you need to apply the 500 rule , link below 

    https://astrobackyard.com/the-500-rule/

    that will help you gauge what you can and can’t do to avoid trailing,

    nice effort , congrates 

    Richard

    Could anyone figure out what mine would be ? 
     

    ive got a canon 700d 

    skywatcher 200p explorer 

     

    also if I get a tracking mount will it solve this issue ?

    That's very good - I'd hate to show my first attempt at Orion! Probably wobble if you're touching the camera to take a shot. Given the angles you're dealing with, the tiniest of shakes will show. Eradicate that and you can start to think about polar alignment to get good tracking. You would like to be able to get 10-20s of exposure time before stars start to trail.

    I did think so. Even though I’m only tapping the screen it’s probably still causing a shake.

    It looks like wobble to me, most likely from touching the camera to take the shot, as you said.

    An intervolemeter is a must if your camera does not have a built in timer function so you can let the rig settle after handling it before it starts imaging.

    Get the wobble under control and you should be good to go...or at least able to identify other issues that may be at play (incorrect polar alignment etc:D)

    what equipment are you using?

    I’m using a skywatcher explorer 200p and a canon 700d 

    Should I have used a Barlow lens?

     

  7. Hi all. 
     

    this is my first shot of the Orion Nebula. 
     

    i think it’s ok. But could be better. 
     

    i tried stacking but didn’t understand how to use it. And every image seemed to have some sort of blur. I don’t know if it would be a tracking issue or my slight tap on the camera screen to take the photo. 
     

     

    I have attached two other photos of the ones I was going to use stacking with but they’re just ever so slightly blurred.  The exposure of each shot was around 3 seconds. Anything longer and they start to blur even more so

    I’ve ordered the mask for the scope also. 

    any advice appreciated.

  8. Hi everyone.  I recently had a powerseeker 127eq but I sold that and got something with a bit more ‘umpth’

     

    i now have a skywatcher 200p 5eq.

     

    ive got a canon 700d and I’m wondering what kind of settings I’d need to capture the Orion Nebula etc. 

     

    i have all the necessary adapters.  

  9. Hi all

     

    i just got one of these cameras from Amazon. 
     

    ive plugged it into my mac and it just won’t work. I’ve tried oacapture and astrodmx 

    oacapture says unable to connect astrodmx says access denied. 
     

    ive downloaded an application called manycam which finds the camera and displays it on the screen. 
     

    i can only assume this is a software permission issue? 
     

    as both the former are from untrusted developers according to apple. And I get a warning when I try open them. 

  10. Thank you for the replies. 
     

    you’re right, for now I will focus on learning how to use the telescope. It looks ever so complicated. Wish me luck lol. 
     

    im in the East Midlands. In a Little village which is pitch black at night.  
     

    just waiting for a clear night now. 
     

    il check out the moon later and see if one of the pieces is correcting. 
     

    thanks!

  11. Hello everyone. 
     

    ive just been gifted a Celestron powerseeker 127eq. It came with two 20mm lenses and one 10mm lens. 
     

    i haven’t managed to use it yet as it’s pretty cloudy. 
     

    I’d love to be able to see Saturn and perhaps Jupiter. I’m unsure what lenses I need? 
     

    I’ve read a lot about a Barlow lens? 
     

    If anyone could shed any light. Thanks :)
