  1. Thanks @newbie alert, I will try the PHD2 drift tool (unfortunately I don't have views of Polari from my little observatory). Also thanks @Cosmic Geoff, I will try what you suggest, while I wait for the bearings to arrive. I already have received the new DC connecting set: Which I purchased locally (since the shipment costs to my place from DigiKey were astounding). Best regards, NV
  2. Thanks for sharing your experience @Cosmic Geoff. I will be in the lookout for the situation on the "large adjustment nut". About using the CPC on a wedge for DSAP (Deep Space Astrophotography), yes, so far I am not having much luck, even after using the f/6.3 reducer-corrector. I still need to try with a camera that have a bigger sensor than the one I'm using (an imx290 that I bought for planetary imaging). Thankfully I also have a Cannon 600D, so I will be able to test this assumption . Yesterday I also noticed that the DC socket is a bit loose (which was the cause for some connecting issues that were driving me crazy!). Now I also have a new task to add to my to-do list (thankfully there is an excellent how-to in IFIXIT by Michael Wofford), together with cleaning the inner part of the corrector plate . Best regards, NV
  3. Hi all, As some of you may know, I am the (proud) owner of a second (maybe third) hand Celestron CPC 800 which, on the past, has required some adjustments. Lately I've moved it into a little observatory I've made at my home and, to make things more interesting (ha ha) I placed it on a wedge (hoping to try my hand with AP, although I'll be perfectly happy if I get to make it work as an EEVA setup as well). The thing is that, since the scope was placed this way, I've noticed that, sometimes, it gets sort of stuck in the RA movement every now and then. This is clearly noticeable when moving it with the clutch off (disengaged?) however, if I force to move it back and forth a few times (also with the clutch off), it goes back to normal. I've looked around the Internet and, after finding Gary Bennett's excellent article "How To Replace Factory Original Nylon Azimuth Bearing Balls" , I believe that I need to take a look at how it is the situation with my CPC's bearings and, since for doing so I have to go through the task of dismantling it, I've already ordered new bearings, just in case. However, before doing anything, I would like to ask you about your opinions on its guiding performance, which you can see below: If I am not mistaken, I remember reading somewhere that normal accuracy for this kind of setup is about RMS 1.25", but I haven't been able to find the source again... Anyway, if this is true, this is more or less what I get in Dec. Best regards, NV PS: I believe that I have the scope pretty well balanced (meaning that it doesn't move on its own when the clutches are off) by using a proper rail counterweight and two workout ankle weights, wrapped at the holder placed in lighter arm, as you can see below: PSPS: Also, please notice that PHD2 Log Viewer says that in the session I had a Polar Alignment Error of 11.6' (despite my having performed one ASPA).
  4. Hi all, Last night we've got an amazing view of a Moon's halo (with Mars!) over here: Canon EOS 600D astromodified Tamron AF 17-50 F/2.8 (IF) ISO-3200, 2.5 s F/2.8 Thanks for looking, NV
  5. Hi all, I've added a little roof to the rack so no water can fall on it from above (or from its side) and I'm now looking into ways for connecting the aluminum grid to ground and to add a polycarbonate lid as well... So, definitely, this is a work in progress. Meantime I've been doing some tests on my setup and today, after replacing some dodgy connectors, everything was working like a charm :-). I also took this gorg eous picture with the usb-monitoring camera from "the control room" ( aka my little office): Thanks for looking, Carlos
  6. Hi @Peter Drew, I live in El Médano. How is the weather like by the "farwest coast" (so to speak)?. I have an amateur astronomer (and amazing photographer) friend living in Arona and he always complains about the clouds falling from the mountains when he has all the gear set up (he has pretty good views to La Gomera and the SW sky, though). Hi @Rusted. Thanks for your concern. Maybe I should have said that, when wiring this room, a dedicated RCD (residual-current device) was installed in the electric panel. Anyhow, for the sake of safety, If I understand you well, what I need to do is either find a way to isolate the power supply's enclosure or replace it altogether by something like this (*): Or do you mean that I need to encase the entire rack?. This could be tricky, since hunging wires need to get out of it, and also both, the power source and the computer, need to be ventilated for them not to overheat. Regards, NV (*) With 8.3A I think it is a quite oversized , but the step right below this one seems to be of 2.5A which, I think, is not enough for my telesscope (now I'm using a 6A one).
  7. Hi all, Since nothing but clouds (or dust or wind) have been coming my way, I decided to make some improvements, starting by following @Synchronicity suggestion to wire the power source from behind. Also, I added a red led strip controlled by a potentiometer, as you can see below. Thanks for looking. NV
  8. Thanks @Synchronicity, yes, that is the way I've been told by a electrician friend of mine I should do when cabling electric wires outdoors. But this is not the case, I won't open the roof if it is raining. Or do you expect that I'd have that much condensation around here?. I placed all connections on top because what I do expect is for the cables to get wrapped arround the mount sooner or later, so that they will come out and disconnect before producing further damage. Does this make sense?. Regards, NV
  9. Thanks for your concern Michael, You are absolutely right and rest assure that I'm working on this. To be honest, living at the South side of Tenerife and by the sea, I'm more concerned with salty haze, wind and dust than with rain (although last week we had a rare episode with quite a lot of it, by Canary Islands standards, that is, and I got some water leaking where the roll-off roof meets with the other roof, fortunately that was away from the electric stuff). While I find a way to add rubber bands to the closing surfaces and brushes (or something like that) to the roof rails, I'll add a little roof (or better a full cover) for the electric components as soon as I can. Initially, I was considering to install a Gewiss IP56 enclosure with a transparent lid, but they were way too bulky and troublesome to get opened and closed... Regards, NV
  10. My 5 cents here: I also have a (extremely tall) street light right in front of my house and, although a technician at the city council has assured me that is looking for solutions for that, the truth is that nothing has been done so far (two years and counting). My first try at solving this was to go bold and paint it with red paint (by using a combination of a windsurf mast and a brush extender, and what a very difficult task that was, I can tell you!) and it worked wonderfully during three days, which was how long it took the city council to come and clean the mess I made (probably tipped off by my neighbours). My second try was to install a black retractable side awning, similar to this one, which more or les worked, as long as you placed the telescope very close to it (which also meant to block most of the available sky). I don't know, maybe this could be a solution for you as well. Best regards, NV
  11. Hi all, Can you see the pictures now?. Regards, NV
  12. Weird because I can see them... Tomorrow I'll edit the post and upload the pics instead of copy&paste them. Sorry mates and thanks for noticing. NV
  13. Hi all, Although the observatory is still a work in progress, this weekend I decided move in the telescope and see how everything looked like (and worked) in place. Here you have a picture showing how the observatory it looks like form the outside: Here you have the telescope already placed in the observatory: And here are the electronics I've placed so far. Notice the mini-pc that serves the telescope and the little webcam at the corner, which allowes me to monitor it from "the control room" (actually a small office space that I have at home): This is how the setup looks from the webcam at the control room: Although I'm quite happy about the results, the roll-off roof, which I ordered made specially by ECS, is not as weather tight as I hoped it to be. So, while I figure out ways to improve it, I've decided to add a cover, at least for the telescope: If you'd like further information about my little observatory, please do let me know. Thanks for looking :-). NV
  14. I've processed another video with the same setup. Here you have the result, beside an image from Mars Mapper (copying @chiltonstar's way of presenting) The blob I was referring above was Cerberus :-). I believe I did get an image of Olympus earlier that night, but I had way too much gain in my setup (and probably the seeing wasn't so good either) so it didn't come out too nice: Thanks for looking, NV
  15. Hi @Tommohawk, Thanks for your inputs!. About the colour, I just let Registax to automatically balance the colours. Yes, I agree that the result looks a bit muted. About the exposure time, I tough the same as you did, the shorter the better (with a nice histogram and as a little a ROI as possible, that is) . I'll have to look into this 5-15 ms range because cranking up the gain brings too much noise to the sign. 200 FPS is a dream with my gear (an USB 2 cammera and a 10+ year old laptop) but, well, I've got to fiddle with what I have ;-). About Marps maps, the resource pointed out by @paul mc c is just what I was looking for, do take a look at it. Regards, NV
