  1. Hi all, Trying to improve my images of Saturn before it gets too low, I went up to the Teide National Park, despite the windy conditions (it was about 20 knots by the coast, with gusts higher than 30 knots) and, after quite a lot of struggling up there, when I was resigned to failure because of the late hour (and Saturn already quite far from the optimal position), the wind dropped a little bit and I managed to get the following picture: Now the technical details: The gear: 50th Anniversary Celestron CPC 800 GPS XLT GSO 2.5 Barlow Lens Risingcam GPCMOSS02000KMA ZWO manual filter wheel whith ZWO RGB filters The software: ToupSky (I took 2 minute videos @ 46.69 gain and 26 ms for R, 22 ms for G and 42 ms for B ) Autostakkert Registax (slight touch with wavelets) WinJUPOS (for derotating the video, then back to step 2. and, on de 2nd time to combine RGB) Fitswork (to reduce the background noise) The Gimp (color curve adjustment and a bit of gaussian selective blur) It is amazing what a difference it makes to go up the mountain, I could reduce the exposure time by almost a half from what I need by the seaside. With less wind would I have got the elusive hexagon?. Regards, NV
  2. Is this the price for the head only or also comes with the column and the tripod? Regards, NV
  3. Hi all, After replacing the broken altitude motor in my CPC, last night I took it outside for testing it and made this picture from my terrace by the seaside (with a lot of sea dew depositing on the corrector plate and a seeing of about 1"-1.25"): The gear: 50th Anniversary Celestron CPC 800 GPS XLT GSO 2.5 Barlow Lens Risingcam GPCMOSS02000KMA ZWO manual filter wheel whith ZWO RGB filters The software: ToupSky (I took 2 minutes @ 46.69 gain and 45 ms for R, 40 ms for G and 80 ms for Autostakkert Registax (slight touch with wavelets) WinJUPOS (for derotating the video, then back to step 2. and, on de 2nd time to combine RGB) Fitswork (to reduce the background noise) The Gimp (color curve adjustment and a bit of gaussian selective blur) Probably a bit overprocessed, but considering the conditions, I'm quite happy with it :-). Regards, NV
  4. Hi all, This is the final chapter of this story which, as you can see below, had a good end : I took this picture of Saturn last night from my terrace (by the seaside, with a lot of dew coming from the sea and leving the corrector plate pretty dirty) and it was such a pleasure to have my CPC not only back to life, but operating way better than it did before . The target stayed centered and practically unmoving for minutes and minutes, without having to manually recenter it!... Such a pleasure. Now the technnical details for the picture (in case you were interested): The gear: 50th Anniversary Celestron CPC 800 GPS XLT GSO 2.5 Barlow Lens Risingcam GPCMOSS02000KMA ZWO Luminance filter (I also took RGB videos but I haven't had time for processing them yet) The software: ToupSky (I took 3 minutes @ 46.69 gain and 15 ms) Autostakkert Registax (slight touch with wavelets) WinJUPOS (for derotating the video, then back to step 2.) The Gimp (color curve adjustment) Regards, NV
  5. Thanks @symmetal, I think I'm going to see how it behaves by trying gotos and doing tracking before. If it does work properly (fingers cross), I'll let it be as it is now. By the way, from the three screw sockets only two are actually in use (by its corresponding screw, I mean). The third is not needed because the motor is fixed to a kind of holder which is the one that lets room enough for the oscillations to hapen without afecting much to the shaft. Pretty simple but well thought of engineering, I think. NV
  6. Thanks @Lonestar70 but this is exactly what I did. Anyway, I uninstalled it and looked at the flat part and it did have the mark of the screw, so I did place it properly... Then I reminded that the azimuth motor was exactly the same and decided to take a look at it and, yes, as you can see below, it also oscillates: Therefore either they are both misinstalled or that is the way they are ment to operate. Hopefully tomorrow (or rather later today) I'll get a chance to try it out properly. Best regards, NV
  7. Hi all, Finally I received the motor and, before I did the replacement I conected it to the board in order to test it and, yes, as you can see in de video below, it did work (hurra!): https://youtu.be/rmx6skIi_1c However, after installing it, I noticed some oscillation in the entire motor set, as you can see in the video below: https://youtu.be/m94rUzcQaBU Since I never saw it working before its failure, I don't know whether such oscillating movement is normal or not. Can you please help me out with this?. Silly me, I've justo noticed that I had my phone's camera capturing video in slow motion so it is hard to noticed the oscillating movement. Ah well, I've uploaded yet another video at normal speed below: https://youtu.be/1MV6Dd9u9O0 Hopefully this one is more clear :-). Best regards, NV
  8. Here you have my own try on adding false colour with the Gimp. I used a tutorial that I found on the Internet and translated it to the Gimp as best as I could by using @Nigella Bryant version as my template:
  9. Thanks @stargazer33 and specially to@Nigella Bryant. I love it!. I tried to add color myself by using gimp but could't. So much to learn... Actually, I sent the picture to a friend who is a professional astophysicist and he told me that to get granulation you need seeing of about 1 arcsecond. Since I live at the seaside, he suggested me to try taking these pictures early in the morning, the colder the day the better and as soon as The Sun gets higer than 20 degrees from the horizon. The 0.85 reducer/flattener is already in my wish list all right ;-). NV
  10. Hi all, Here you have a picture I've just made (and processed) of The Sun: The gear: Sky-Watcher Evostar 72ED DS-Pro Sky-Watcher HEQ-5 Baader ASTF Risingcam GPCMOSS02000KMA The software: ToupSky (I took 1000 frames with 0 gain and 0.428 ms) Autostakkert The Gimp Making focus was a real pain because there are no spots at all... At least I managed to get some granulation :-). Regards, NV
  11. Thats right, I've just check. Both holes have the same diameter (2 cm) but the black HEQ5 ones have an inner plastic that reduces it to 1.8 cm. The down side of hammer the plastic out is that the counterweight will become looser when using it with the HEQ5, I think. NV
  12. They took quite a while to arrive but finally the eq3 counterweights are here and, as @Stub Mandrel said, they fit nicely at the heq5, as you can see in the picture. Thanks a lot NV
