  1. Thanks for the great comments guys Erik
  2. Hi guys. Sorry I have been absent for such a while! I just realised it's been about a year since I posted here last! How slack haha! Been busy with work, and buying of a new business, and haven't had much time to get outside, plus the weather hasn't been really great or consistent, but I have managed to get a few images in! Thought I'd share the best of what I have achieved over the past year, hope you like them All were imaged through the RC10 on the G11, in Lakes Entrance, Australia. With the Sculptor Galaxy, it was my first image with the new QHY9, and I used the wrong setting, so there is a slightly noticeable band across the lower half of the image. Tarantula Nebula in Ha, 6 Hours, 36, 10 minute subs, binned 2x2 with the QHY9 Eagle Nebula, 11 Hours, 44, 15 minute subs with the QHY10 Sculptor Galaxy 6 Hours Exposure (First light with the QHY9) 3 Hours L, 3 Hours RGB Keyhole Nebula, 2 Hours, 8x15 minutes with the QHY10 NGC 4372, 3 Hours, 18x10 minute subs with the QHY10 Gabriela Mistral Nebula in Ha, 10 Hours, 30x 20 minute subs with the QHY9 Gabriela Mistral Nebula in HaRGB, 25 Hours total, 15 Hours in RGB+10 Hours Ha, with the QHY9 Thanks for looking Erik
  3. Thank you for your replies William, I am not sure what the decoupler ring is supposed to look like, so I can't be certain, but there was something about a redesigned, or upgraded focuser mentioned in the paperwork with it. The only "Ring" it has on it is like an aluminium collar used to screw the focuser to the body of the scope. It doesn't have any type of adjustable screws or anything. The moonlite however does have four tip/tilt screws, but the recommendation was only to touch them if there was a defect in the OTA's optical alignment. I'm not sure how to test for that. I will attach the stock focuser and see how it behaves with the TAK scope as well maybe? I agree that the optional decoupler ring may not be necessary, as the moonlite is able to be adjusted. Like I said I am reluctant to turn anything as it is apparently perfectly set in the factory. However the scope may be out of wack? I do have a Glatter collimator. It also disagrees with the star test, and again, with the laser in the moonlit, when I rotate the focuser around in a circle, the laser spot follows a non-concentric circle in respect to the secondary spot. Then again, it is only held in by the compression ring. I can't help think that the focuser must need adjusting, not the secondary, because according to my star tests, the secondary doesn't need touching. I will see what happens with the stock focuser and keep in touch. Erik
  4. Hey all I started a thread here a while ago, probably close to 12 months ago. I was having conflicting results from my TAK collimating scope and star testing my GSO RC10. I took a few measurements and put it down to the centre spot on the secondary mirror not being placed correctly (now found to be incorrect!) I proceded to collimate off the star, and imaged away, things seemed ok, been getting good images, but I wasn't 100% happy. Today I have confirmed that the centre spot has been placed correctly on the secondary. I am a bit lost as what to test next?? When the star test shows concentric circles, the TAK scope shows the centre spot incorrectly, and vice versa. I'm not sure how to explain this and have it make sense to you guys! I'm hopeless when it comes to putting things into words lol! Let me know if I need to clarify something. 1.) I have been playing around with the moonlite focuser. I found, that when looking through the TAK scope, and rotating the focuser around, 360 Deg, the FOV I can see in the primary, moves around as if an axis somewhere is not in the centre? Like watching a wheel turn, but the axle is slightly off centre. Whilst this is happening, the black centre of the TAK scope moves a little in respect to the secondary spot, but only a fraction of a mm, then returns to it's original, "incorrect" position. 2.) Applying pressure to the focuser body, in any direction, also causes the FOV of the primary to shift slightly. I'm pretty sure the focuser and mirror cell will move as one piece, so what is happening is understandable, but should there be any play here? I don't think this is related to my original problem, but just an interesting observation. Moonlite says that their focusers are perfectly collimated before shipping, so I am a bit reluctant to touch any screws there. I'm not certain, but it feels like the focuser is not 100% centred with the secondary, and I have collimated the secondary to suit the focuser's position, without knowing. Is that possible to do? I can't think why the TAK scope pattern won't agree on the star test. My thinking is that the star test is really the only accurate way of testing collimation, but Something is not right with what is happening? If anyone has any thoughts on this it would be greatly appreciated !
  5. That's a great image! Looks like the bubble is about to pop out of the screen! Erik
  6. Awesome Olly, well done! Erik
  7. Thank you everyone for your great feedback Erik
  8. Thanks guys Yeah that was what I was trying to achieve, to get the blue and yellow tones to stand out Erik
  9. Imaged over a week ago, I only manage to get around to processing it last night. It is my first Globular, and I found it quite hard to process, getting the blue and yellow stars to stand out. Worked out quite well, and I'm really pleased with it. http://www.astrobin.com/full/41785/?mod=none 20 x 5 minute subs. Erik

    Thanks Paul, yes, at the moment it rises to about 50 Deg by midnight. I started imaging by then, and followed it right up past Zenith. Thanks Yeah It looks great though the eyepiece. The red side of the Nebula stands out a fair bit more though. Thanks all for the comments Erik

    Think you may be right. I'll have another play with it and tweak the colours. Erik

    Thanks guys. Yeah that dust makes it look a bit 3D. Really happy with the bright diffraction spikes. Just looking at it again, think there is a bit of vignetting round the centre? Erik

    Hey all. I had perfect timing with the clouds rolling away as the moon disappeared. I decided to revisit one of my favourite DSO's, the Trifid Nebula. I attempted this one last year with my 10" Newt, with OK results, but I think this one topes it. The new RC has been giving me really good results so far, and I'm stoked with this one Imaged over about week with the QHY 10. 10 Hours with 15 minute subs, guided with the ONAG. Hope you like it High res version: http://www.astrobin.com/full/41574/?mod=none All feedback welcomed! Erik
  15. Thank you, yeah I think the background is a bit blue also. I think it's a bit better in the second version, but my eyes started to get a bit tired after staring at both of them for so long! I might have to mask off the light and tone the background down a bit? Erik
