  1. Past hour
  2. What cameras do you have that you can use on this scope? There is no such thing as slow scope for imaging That scope has massive focal length, and that presents some challenges. As far as I know, Maksutovs have fairly flat field so you should be able to use fully illuminated section of the field without any sort of correction needed. Quick search gives fully illuminated field of about 30mm (but don't quote me on that one - I'm not 100% certain of it). With focal length of 2700mm, this is equivalent of 15mm/1350mm, or 7.5mm/675mm. By no means wide field setup, but should be capable of capturing galaxies, planetaries and globular clusters. To be a good match for this scope, camera should have more than 14um pixel size. Of course, you don't actually have to have such camera, any camera will do if you bin it to required pixel size / resolution. Let's say you pair it with ASI071 You can get 1236px x 821px image covering ~30' x ~20' of the sky with resolution being 1.46"/px at 180mm aperture. I would not call that slow, although I would call it "constricted". But not much more than for example my 8" RC paired with ASI1600 which gives me 37.2' x 28.2'. Trouble of course is to find suitable mono camera for this scope that is affordable. Only options at the moment are expensive CCD sensors close to full frame. KAF-16200 would be good choice (not that I'm suggesting to get one just to use it with said scope )
  3. I’m not sure about imaging DSO’s But, I have taken some great planetary shots with it, shame it’s sitting on a shelf really.
  4. This one does not look like a Man's Cave at all!!! And where should the main lab go? To collimate, to solder AutoFocuser... drill additional holes for mounting plates and etc? no, thanks.... not for me... I am way too lazy to clean 3 floors on a weekly basis.... P.S. How to get to the second and the third floor? I have not noticed any teleporting device in the picture...
  5. Item delivered and hole cut thanks
  6. Sounds like a lovely little scope. Any photos of the little champ you can share?
  7. Thanks Wim, yes ignorance and stupidity combined with wealth is apparently a popular subject!
  8. Don't know if you have already, but if you have the Time of Minimum for primary and secondary, you can submit for inclusion in the JAAVSO - there's details on the AAVSO Eclipsing Binary page. Cheers
  9. I bet you there is already some twit that has put an observatory on to the top of his super yacht.
  10. Nice observation (And yes - this is an object with requested observations as it goes towards a predicted increase in brightness when the smaller black hole passes through the theorized accretion disc of the second - I had a go at magnitude measurement a few weeks back but got clouded out...). is correct for the naming source, but it was named as such because Blazars encompass both BL Lac objects and OVV (Optically Violent Variable) quasars as sub types. (The distinction being the BL Lacs are related to radio weak galaxies, whereas OVVs relate to radio loud galaxies). In reality, Blazars are a sub-type of the larger quasar group ("Quasi-Stellar Object" - appears point like like a star, but the spectra/variability is non-stellar), where the relativistic emission jets of the feeding black hole point along the line of sight for blazars - BL Lac and Blazar are often used interchangeably, but that's not quite the whole story
  11. I have one of these scopes which in truth is only sitting on my scope rack dust collecting. Has anyone tried the Meade F 6.3 reducer on one of these and is it possible to image with the. I realise even if the reducer does work it will still be slow and fairly long F/L. I have a Brightstar mammut which I have never used with fairly large pixels that may work on it ( at least I think it will ) I believe they are 8.6 x 8.3um. Any thoughts, even if it's forget it. Alan
  12. They normally use a robot to secure the F9 cores to the deck of the droneship. This robot wasn't suitable for the heavy core and they only secured one leg. The droneship was over 900Km out in the Atlantic- far further than a F9 landing- and hit very heavy seas with swells over 8 metres. I saw some figures on the core entry- it was moving at 10,300 km/h at MECO and would have accelerated as gravity took hold. That was a LOT of energy to dissipate without destroying the core. Hypergolic fuels take no prisoners. When they go bang the don't do it by halves. This is why they test though...there's only so much you can do in design. Spaceflight is HARD and there's a million different ways to get it wrong and only a single way to get it correct. It was like the failure of the COPVs. They move fast though...only 6 months after the COPV failure to the release of the findings.
  13. It's just a ploy to part the fool from his money, a toy for a wealthy twit, you'd be better off with a superyacht to get to dark skies and and a deckchair and stabilised binos to watch the stars when the captain turns the lights out for you. Now where's my Euromillions ticket...
  14. Isn't the equipment somewhat essential? Being short sighted, I need "equipment" just to look up at a clear sky. This thread hasn't been hijacked, has it? We were discussing the reasons for not posting a "List of members equipment at foot of post."
  15. Isn't this supposed to be a private dwelling? I am Dutch, but when I got to a private party, I don't expect to go that way. (If you catch my drift.) I expect free drinks and free views. (Oh @gorann, what a nice thread you started.)
  16. Today
  17. I have a 70mm - 300mm lens second hand coming in the post soon. So i can have a play and see how iy compares.
  18. Wearing my Heath-Robinson hat, the question of internal temperature could be overcome with a Peltier TEC and inside/outside heatsinks and fan(s). Cooling the internal air when too hot and warming it when too cool.
  19. Excellent looking prom capture, about the action around at the moment.
  20. It's a cross-section drawing except for the dome. Well, I say "drawing" with tongue in cheek! More a sort of "artist's impression" by a failed artist. The dome isn't over the telescope so no views would be available (or very restricted).
  21. Still some nice proms around, despite the minimum
