In the immortal words of Britney Spears... oops I did it again. I think I may have a problem...
Couldn't resist this lovely old thing though and did, I think, get a proper bargain if all's well.
This one has Eiko (Circle upside down "Y" Hilkin, Carton etc) optics, 60mm, 800 Fl - so f 13.3 so am hoping for something special for retro double-star & lunar work, will update here on condistion when it arrives.
As an aside, although my expectations are not high, I can't wait to try the "Super Ramsden" eyepiece - sounds like something out of Wallace & Gromit
I was watching a few old refractors on EBay and got carried away with all that wood & the carefully written index card...
Its a Prinz 330, in theory the optics should be OK-ish (Japanese Circle T) and I'll have something super cheap that's a nice object & will do a job to have a go at solar (with appropriate modern filters of course - not the passport to blindness included with this kit).
Also prevented me from bidding on a lovely looking Pentax J-60 that is going to go for way more money than I wanted to spend on this whim
Look forward to updating on whether I have bought a pile of old rubbish or a usable piece of nostalgia in due course...
I'm going to rent a pier in shared observatory at Astrocamp.es Nerpio, Spain.
My setup is 10Micron GM1000HPS and I'm planning to order Lacerta Photonewton 200/800. It's well corrected carbon fiber Newtonian.
I don't require any equipment being contributed, just rent 50/50. Total: 300 euro+Tax. hence 150 euro +tax per person.
I'm addressing this problem with our Scopedome shutter since December 2020. The problem occurs every once in a while either during opening or closing the shutter especially approaching the full-close position wherein it creates a loud "bang" noise.
After inspecting the dome, I just found out that the gear is now not touching exactly the latch hole of the shutter. Herewith attached below are the images showing the problem.
Any tips/suggestions on how to resolve this issue, particularly on the aligning them, what to use etc., if needs replacement?
Excuse me if there are incorrect terms. I'm not that familiar with dome components.
Thank you very much. Clear skies.
Hey guys, hoping to launch my Observatory build this year (2.7m Pulsar), and looking for some advice on electrical requirements. Apologies for the brain dump, but when I started typing this up, I just seemed to keep coming up with other questions:-)
My observatory site will require a 20m cable run from the house, which I am hoping will be as a spur off existing circuitry, although still to get my tame electrician to give me the low-down on the best solution.
Normal approach is to run a sub-surface conduit for both data and electricity supply, however it occurred to me that an alternative approach might be to have above surface conduits running from a supply point at the house to a receiving point at the observatory, somewhat along the lines of caravan hookups at camping sites. Would be interested to hear from folks on this approach, especially if anyone has gone down this route.
Assuming we go down the sub-surface route:
1/. What would be an appropriate depth to lay the power and data conduits?
2/. Has anybody had data quality issues when running Ethernet in close proximity to a power conduit? Data medium will be over CAT6, so I’m hoping that the more stringent specifications will be sufficient to remove this as a possible problem. I’m aware of general protocols, which advise against laying data cables parallel to power cables for extended lengths. In the event that this is still an issue what approaches have people taken to providing similar data solutions for their own observatories?
3/. I’m also interested in future proofing the obsy with regards to power sockets. Straight up, the following supply requirements spring to mind:
— Dew control (transformed to 12V DC). Possible I may continue to use my existing batteries for this purpose. How have you guys tackled this?
So I’m thinking 4 double sockets should cater for these and provide me with sufficient expansion for unforeseen circumstance. Is this sufficient? Am I missing something?
What is the maximum advisable current draw? Intention is to have all supplies run through a fuse box local to the observatory and of course all plugs will utilise standard domestic fuses as well.
With regards to lighting what solutions have you guys gone with? I was thinking about just using a single standard red outdoor light, but it occurred to me that shadows might be an issue and so got to thinking about a surround lighting approach, perhaps using something similar to this:
On the possibility of an entirely WIFI based approach to data. Is this realistic? This would likely require booster units for the existing house WIFI, however I’m thinking that even then, data transfer rates for imaging might be an issue if I graduate to remote operation.
