  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. 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?? ?
  3. Hi julian489289 what setting on PHD do you use.? Are you Drizzling as well? I wondered what those blips were on you PHD data graph Alec Like ThisCelestron 8SE, Skywatcher Evostar 80ED DS-Pro, ASI120MC, Canon 1100D & 550D modded, AZ EQ6-GT Hi Alec, I dither between subs and I have found that you must increase the pause between exposures sufficiently enough to allow PHD to settle down after each dither. I do also drizzle 2x in the stacking parameters. The blips are a graph setting which show when a correction has been made by PHD. Julian
  4. Thanks to all of your advice. Leo Triplet in Leo Explore Scientific APO 102mm, Canon 650 D Unmodded camera on a SW HEQ5 mount. These subs were dithered to minimise noise. This result is 10 x 600 second guided subs with associated calibration frames, 3 darks, 25 flats & 25 bias. Shot at ISO 400 Has been stacked in DSS with x2 drizzle function and then been processed in PS CS6 using Noel Carboni's tools. This is my best attempt to date of this target and probably the last this year.
  5. Thanks A G . Yes I must agree it is a great scope. Thanks for your and other member's valued input it has been most helpful.
  6. Thanks AG. I have my dither set to 5, so I would assume that would be classed as extreme. I usually set the delay to 5 seconds but may now increase that to 45s for the guiding to settle down?? I am not too sure of the theoretical resolution limit of my scope and camera combi though, Explore Scientific 102mm 714 FL APO and Canon 650D.
  7. Thanks AG. You say that the effective use of drizzle is subject to certain conditions re scale and subs. What are those conditions so I know if they can be met or not? Is it not right that If I am dithering my subs that I need to drizzle??
  8. Thanks Steve, I was just told that if I dithered I needed to drizzle!!
  9. Hi Marky1973, thanks hopefully it will work and will have to try x2 & x3 to see what difference it makes to a normal stack?. Don't really know what the drizzle function really does? I thought that it improved the area of interest but don't really know why or how?? Hopefully someone can shed some light on the benefits of drizzle??
  10. Thanks D4N. I am not familiar with the red region of interest box to stack only park of the image that one wants??
  11. I use an 18mp Canon 650D DSLR for my imaging and stack images using DSS. I have no issues stacking my images in DSS usually. However, recently I have tried to stack using the x2 and x3 drizzle function. DSS takes a while longer to process with these drizzle options and stacks all of my subs. However, when the program moves to autosave the stacked result, DSS shows a yellow exclamation mark in a triangle and goes no further. It gives no error message. Has anyone else had this issue and how did you resolve it? Is the18mega pixel image too much for DSS to stack in drizzle mode? Hope you guys can help, thanks Julian
  12. Well I finally got out on a clear night to try out guiding with PHD2. With all of your kind help and suggestions, all of the issues that I had before are now sorted, with a guiding rate set at 0.5 this sorted the calibration and gives a great looking graph. On calibration, set at 1850 with 0.5 set, PHD calibrated itself with only 7 steps in each direction. Previously it was over 40 steps on some occasions. 10 minute subs with pinpointed stars, PHD is fab!! Thanks again
  13. Also I have found a version 2.5.0, I will try this as well
  14. Do you think changing these settings will sort how the cross hairs track the star on calibration ie returning back to the star before doing north south ?
