  1. Hi Sheeprug. My telrad has just failed in the same way. Everything else works just fine it is the red circle LED that has failed. Where did you locate the new one that you used to replace your defective one please? Thanks Julian
  2. The Theia90 1/10th wave star diagonal is a combined star diagonal and filter changer, with a micro meter tip / tilt adjustable mirror.

  3. Is anyone using one of the new Altair Astro Hypercam 1600 mono cameras? I am keen to move from a Canon 650D DSLR to a CMOS camera. I like the 1600 mono camera and see many great results from the ZWO ASI 1600m. The Altair Astro seems to have a slightly better spec so I was after any reviews on this camera?? ?
  4. Thank you Vlaiv, I appreciate your response. A new storage hard drive may also be required then!! ?
  5. Thanks Sam, that's a cracking result and doesn't appear to have much noise either. You have set yourself a steep learning curve though, new camera, new acquisition software and PI ?. I have read various reviews of this camera and one downside I have seen is that the sensor window is not AR coated. However, on the ZWO spec for this camera it states that it has AR coating?? Can you confirm this? I am so tempted to make the jump and order this camera, the ZWO 7 position FW and Baader 36mm unmounted NB filters. With NB though, do you find it more difficult to find a decent star to f
  6. Hi Sam I am considering the move from Canon 650d to a CMOS. Been considering the Altair Astro Hypercam 183m pro cool or the ZWO ASI 1600m pro. Obviously you went for the ZWO, now that you have it and played with it, is this the camera to go for?? Also what filter wheel and filters did you go for??
  7. I am about to purchase Gradient XTerminator, this should help me in this situation. Thank you again, your help is very much appreciated.
  8. Thanks, that explains it I think Canon has an option and can take a light frame & then a dark frame straight afterwards. I wonder if this would help??
  9. This is a single light frame pre flip (converted to jpeg as tif too large) This is a single LF post flip (inverted prior to stacking in DSS to match orientation of those images taken pre flip)
  10. Vlaiv, this is a copy of that image. It appears that the AG is repeated on wither side when I only get the glow on one side. Was this due to the flip? No other light leakage, view finder covered as well?????
  11. I am a little confused with my calibration frames after a meridian flip during an imaging session. During the session, half of my light frames were prior to and half after a meridian flip. The images after the flip were 180 degrees out to those prior to the flip. Therefore, in my saved directory, I just flipped the after meridian flip images 180 degrees to match in with the pre flip images prior to stacking in DSS. The camera orientation to the scope was not changed, the mount just flipped after M31 went through the meridian. This raised the question, when I take my flat
  12. Emil, nice neat work dude. Mine gets a bit crowded with wiring as the box is a little too narrow to take the battery and other gubbings side by side
  13. Just completed my modification to ensure that one socket which powers the mount supplies 14.5v and the rest 12v. Rather pleased with the result. Also replaced all wiring inside with silicone coated 20a wire.
  14. Really sweet mate. Just ordered that voltage current meter/display for my box. Going to use the current voltmeter already in use to monitor the output of the boost convertor (when it arrives!!)
