  1. What happened to the iOptron CEM120

    well well : https://www.ioptron.com/product-p/7300.htm
  2. That is a quite wonderful visual setup, I hope it serves you well. Great to see a Panther in action, intriguing mount.
  3. Primaluce Eagle manual

    PrimaLuce rock. They knew what the password was and replied to me on a Sunday, in time for some playtime tonight under the Moon. They even had a sense of humour about my stupidity. Can't ask for more than that, legends.
  4. Primaluce Eagle manual

    Thanks. Wish I had read this before I threw away the box
  5. Primaluce Eagle manual

    Cheers. My interweb search-fu needs some work it seems 😁
  6. Primaluce Eagle manual

    Thanks - The default wifi password is the first hurdle 😁. I imagine everythjng else is pretty straightforward. Yes, the Eagle2 one.
  7. Free online course heads up

    I did this course a couple of years ago and thought it was absolutely brilliant. It is now back and enrolling if anyone else might be interested. I still watch the videos on occasion. Duke University's Introduction to Astronomy course taught by Professor Ronen Plesser http://duke.is/su9c13
  8. Primaluce Eagle manual

    Anyone got a pdf of the Pimaluce Eagle manual? Am setting up my new one this weekend and either did not get a manual, or have misplaced it. Waiting until Monday to play with my new toy is killing me :). Cheers Matt
  9. Final F9 Bubble

    Cheers Chris - Once the results came out from the first session, I was committed to a long one
  10. Final F9 Bubble

    Thanks Chris - you should have seen my first attempts - persistence and some good advice and encouragement are the reason this worked out for me.
  11. Final F9 Bubble

    Thanks Rob! I did think I may need a tilt adjuster, but thought it would just confuse matters as I had enough different factors to get right to start with, which is also why I went native FL even though I have a 0.67 reducer. I don't think I need one for how it is working as it stands, and given it works, I am very loathe to touch it now :). I have a baader diamond and the motorfocuser, but couldn't even work that out so focused manually with a bahtinov mask for this image, which is another factor in doing a single channel per session! This image has changed my plans to be honest, I was not expecting an F9 setup on an HEQ5 to be much use to me as a DSO setup. It was earmarked for photometry and spectroscopy work, I was just playing around to get everything collimated etc first. The Chroma filter was just being tested as well, that was earmarked for my AA115. Given it has managed this, I am not touching it and having it as a long FL rig :). I will move all the science plans to my Mewlon, which I have just bought the Tak reducer flattener for and will give that a go. Even longer FL for that one, at 1700 reduced though !!
  12. Final F9 Bubble

    First real foray into long FL imaging. Many thanks to all those who helped me out in my voyage of discovery thread with advice and encouragement. This is final version - for a while at least! This is the often imaged Bubble Nebula in the Northern Skies. This was taken with my astro bargain of the decade Altair Astro RC6 at native F9 (1370 FL). Atik 414ex camera on the mighty HEQ5. I decided to really go for it for this image, so went for a complete night's session per channel and to get as much Ha data as I could stomach. HaRGB image. Baader RGB - 5 mins subs each. One session per channel ~ 60 subs each. Ha - Chroma 3nm - 38 x 20 mins subs - 3 sessions. 29 hours total! Processed in PixInsight in the end. I tried Photoshop, but my skills were just too rusty! Another day maybe...
  13. The Horse so close you can almost pat it

    That last one does it for me too, that wispy section under the nose is awesomely done in your work here.
  14. The Bubble. An ongoing project.

    Here is another version which takes the stars from the RGB and is more of a superposition rather than an LRGB combination. It allowed a bit more sharpness without crunching the nebula too much and also makes the image a bit brighter as a result as the stars are less soft. Still not quite right, but slow and steady and all that. Thanks for all the feedback, it really is appreciated. Astronomy and imaging in particular can be a bit of a lonely furrow... EDIT: (may be a bit too bright now i see it online!)
  15. The Bubble. An ongoing project.

    I agree - pulling out sharp data from an oversampled image is tough. I am running at native focal length, a mighty F9, so long exposure times too, and haphazard guiding, so a softness is to be expected at < 1"/pixel I guess, but I still think I can do better. The stars in this are still a bit sucky, despite a better effort at the nebula itself. The Bubble looks nice, and I think it could be sharpened in a non-plastic way a bit further, but the stars could be significantly better. The Ha gives such great detail, but mixing that with RGB with stars about x10 the size is the challenge next methinks as there are halos and a lot of the star fuzziness comes from trying to fix that.
