  1. Clutch levers locked Move the counterweights out a bit to balance the scope, check the balance with the levers unlocked.
  2. The certainly look like Meteors to me. I well remember the excitement of my first "blips", excitedly pointing at the screen and wife's response. " That's very interesting but what would you like for tea..........." Regarding large space junk or the ISS reflections, The radar sweeps across the sky so you should get a series of "blips" that slowly descend in frequency and the timings can be checked using ClearOutside and other web sites. Perhaps others have suggestions as to the slowly descending signal
  3. I have Linux (Unbuntu) and Windows laptops and one 500 gb and one Tb external drive. The processed images are stored on both laptops and on both external drives. The external drives both have copies of the Fits data and Avi files. When imaging I use a 16 or 32 gb SD card for the initial data capture.
  4. A lot of newbies struggle with collimation and we get a lot of questions about it at the club. You will get better at it with practice. One problem I see is that overtightened tilt screws form little dimples in the aluminium body of the secondary mirror support and these dimples force the secondary back into its original position when the screws are nipped up so try not to over tighten the three outer screws.
  5. Look up Astro Babys Guide to Collimation - Newtonian Telescope - Reflector. Might help.........
  6. Re the post on washing on the line at midnight, If you point the scope at it and back illuminate then you have a means of taking flats....
  7. It depends on you skills in tying in a sensor to your system but the best I have used is ....... Hydreon RG-11 Rainfall Sensor It works on the same principal as modern car wiper automatic sensors.
  8. Hi. Can you post the camera model and which software you are using?
  9. Equipment details EQ6-R Pro, Skymax 180 Pro, ZWO AS!224 mc usb 3.0 2000 frames 50% rejection level, stacked in Autostakkert, processed in Registax 6, image polished with Gimp and windows image processing. Thank you for the praise will let wingman know
  10. My 81 year old wingman who helped me take this image was keen to know so he could add it to his records. Many thanks. I will let him know.
  11. I have looked on my lunar map and elsewhere but cannot identify this part of the moon. Any ideas?
  12. two ghost heads looking away from each other
  13. You holding out on me Bro? I said the camera would improve your guiding. If that's the guide scope what you got hidden in the house that you haven't told me about?
  14. Ok here is what I came up with. Industrial bearing suppliers do double split shaft clamps in incremental sizes so 3x 38mm clamps obtained. I would have liked to have used stainless steel ones but they go from 36mm to 40mm so had to make do with plated steel versions. Some M6 stainless studding cut to 55 mm lengths and three stainless knurled knobs (all from that well know online shop) The legs are adjusted using the Skywatcher clamps and the shaft clamps are then slid up and hand tightened. These hold the leg adjustments and the legs cannot slide up the tubes. I had to make up spacers so that the knobs would clear the clamp.
  15. When you look at the PHD guide log the periodic error really jumps out of the data. Its unmistakeable. Just clear one point for me. I do not attempt a visual guide but just let the mount run...right?
  16. Ah...I see what you mean. The error I am making is that PHD is "guiding" while creating the PEC file which is clearly wrong. Will do your method when the clouds clear.... Thanks vlaiv
  17. I will read the write up on PHD again to be sure but it does say you can run both together. My experience is that once you have created a PEC file the tracking improves ( the numbers reduce for Dec , RA and RMS). I only get the PHD error when trying to use the recorded PEC file at the next imaging session which points to a syncing issue.
  18. If you set Ascom to record six cycles while PHD is doing its stuff when the sixth cycle ends PEC will kick in and you do see a reduction in the error graph but even though I always park the scope when finished turning on PEC correction at the next session using the file created results in PHD complaining of unexpected movements. As each graph overwrites itself it gives you something to watch while waiting for the next image. I clearly do not yet have a good handle on PHD and PEC but perhaps someone can come in and advise as when it does work it does help.
  19. I used Blocklayer.com to print out the scale. A most useful website.
  20. I made up a device using a finder scope (with cross hairs), a compass and a digital angle finder. I plotted in 10 degree intervals the horizon. Its surprising how a few metres change in location can open up the visible sky.
  21. But Bro, I can't patent it now its in the public domain
  22. I would not use a guide scope for planetary as the exposure times are short. 2000 frames at just over 100 frames per second is an exposure time of 18 seconds. I have seen good results with the moon using small aperture skywatcher maks with Alt Az mounts however for planets the bigger aperture will be of benefit. For processing I can suggest Sharpcap to capture the AVI's, Autostakkert to analyse the frames and stack, Registax to do the initial processing of the stacked image, then Gimp to add some polish and finally a tweak with Windows photo editor if required.
  23. On an EQ6-R I find that the leg clamps can allow the inner leg to creep up the outer when the mount has 16 kg on it. I am a bit nervous about breaking the plastic levers if I go too mad but has anyone else experienced this? I am going to engineer a fix for this problem so its not going to be an issue but if you have had the problem and had to do a fix I would be interested to know how you did it.
  24. I like Mihaighita's method of checking balance as it would also highlight any change in the rotation drag of the mount itself. I used to check compressors by wrapping cord round the drive pulley and using a spring balance to measure the start and rotation pull as part of routine checks.
