  1. Past hour
  2. It was failed sealing that caused the problem with desiccant to dry ordinary air. Maybe I should re-examine my sealing method - I relied on silicone bathroom sealant. For the few days during which the casing stayed sealed and the air dry, the ASC worked perfectly with the water cooling. Except it needed a bit more than the 2W dew heater I was using - that is not a problem.
  3. Not a million miles from you Marvin. The village of Saint-Plancard in Haute-Garonne. We spend about half the year there in scattered chunks. I guess you'd be about a two and a half to three hour drive. I got my 150pds second-hand and, frankly, the focuser was so well-worn I replaced it. So you might need to check the condition if you buy a used version. I have a good spare focuser that I bought for a different project but it won't fit your Space Probe. Have you checked Leboncoin for used 'scopes? There is the occasional bargain to be had through LBC, though most expectations seem way too high. PM me for directions if you fancy a drive down some time.
  4. I think assuming that the accusation is correct without knowing the evidence at this point would be unwise. On rare occasions it can be really quite difficult to tell two honestly-produced images apart short of doing a lot of pixel-peeping and even then if one has been uploaded to SGL and mangled a bit that may not help, though it should hopefully be easy enough to provide an intermediate image from processing to demonstrate one's authorship. Hand it all to the mods and let them deal with it. James
  5. There is a reason why everyone wants to look through the big scopes at star parties..... If you love DSO and can easily get a big scope under dark sky, why wouldn’t you? Paul
  6. ASI 290 - 1,4e Unity Gain. QHY 290 - 1,3e Unity Gain. CSX 290 - 3e Unity Gain ??????????
  7. If it's going to be your first scope then a fast newt isn't a good choice, focus can be very fiddly. A frac is the best option to start.
  8. Does anyone have any thoughts on why someone would post the work of another as their own? Paul
  9. Not a great deal of entertainment in the full disc though they look beautifully sharp. The proms however are very nice indeed. James
  10. Definitely one for the mods to address. The mods work in mysterious ways, but it would be good to know that the matter has been dealt with. Is there a protocol for dealing with these things? If not, one might be a good plan for the future? I should imagine that things could get heated when people’s integrity is rightly, or wrongly called into question. Paul
  11. I would love to see a flat frame. I might be seeing a dark ring in the background towards the corners?
  12. I started with a 10" Skywatcher, and then went for a 15" Obsession after several years. It's better for every type of target, within max fov constraints. In addition to DSOs, it's very good on planets, but note that they will be at low altitude from Ireland/UK for the next couple of years, so views will suffer unfortunately. I was kinda thinking that I should have gone bigger, then saw a 20" Obsession being set up, and saw it drop a couple of feet as the ramps collapsed as it was being wheeled out of the back of an estate car at a star party. I still of course lust after bigger, but I know that 15" is a good, practical no fuss size for me at the moment. What I really lust after now are dark skies, good seeing and transparency... and it all to come together at weekends and to get the opportunity to get out there You only live once: enjoy researching your options, and go for it when ready! PS I'd suggest considering say a 12"...
  13. Heya, Not much sizzling other than a pretty nice big prominence grouping. Had a little time with it this morning. The full disc in CaK Very best,
  14. Currently mount only (but will add guiding asap) and later I will try to get a scope
  15. I assumed that to be the case, though in this particular example I'd not be surprised if the architect had decided to ping people up to the top floor on a length of elastic. James
  16. It’s the business! Have no fear; you have invested well.
  17. Agree with the above. It’s really amazing what you have shown us, a fantastic post and series of images.
  18. I suspect the staircase is a spiral round the inside of the building. Otherwise there's no way to get to the scope. Can't see any way of getting into the dome though, or to get the scope up to that level
  19. Hi cotak, This has not been denied nor confirmed by iOptron. I did ask and they just keep silent about it ... ¿ from where did you get the information or is it based on an ancient post in Cloudy Nights forum ? ¿ or is it an assumption from your side ? Sorry, but I think it is time to put down facts and not guessing or assumptions or I have heard from somebody ... regards Rainer
  20. So I've had the chance to do some work with my replaced Hypercam 1600M over easter, and I must say it has performed very well. I can't wait to try it out on some nebulae after the summer. :) Attached is a very short 75minute RGB of M3 in pretty much full moon which shows in the background noise..
  21. Today
  22. Seems like a fair amount of confusion all round Gaz, not least for myself Hopefully someone can clarify it for us.
  23. I bought the medium format f4 Pentax off Ebay recently and from a Japanese supplier. It cost me £120 with charges and VAT so quite a good price really. Anyway, it's in very good condition and is a lovely piece of glass. I've mounted it on the EQ3 Pro, now with a qhy mini guide scope: It weighed a couple of kilos with the adapter and camera. I initially fitted it to a fs 1100d and did some subs the other week but had problems with the flats not working properly and with red halos around the brighter stars. It turns out I think the halos are caused by the Astronomik cls ccd lp filter... Very annoying but I'm pleased with the lens itself. I've been doing battle with the subs I took - I'm well out of practice with taking and processing dslr pics! I always get terrible lp gradients. I've had Pixinsight for about 3 years... So I finally got around to trying it, mainly to use the gradient removal processes (ABE and DBE). Works quite well but didn't eliminate the gradients entirely . I'm impressed with PI's colour calibration. It's certainly a powerful piece of dedicated astro software. Anyway, here are the subs I took the other week with an unmodded 1100d. Nothing very exciting in terms of targets - just stars, really. The first lot I tried with the FS 1100d were 60s but seemed to be underexposed for the targets though, as usual, transparency was poor. The subs below were all 90s but seemed a bit overexposed - exposed to the right, overall. I'm going to have to try taking 75s ones! Also, I need a lot of them... None of the stacks are very good - if only I got more imaging opportunities.... Some stars in Herc. 23x90s: In the region of LDN712, 7x90s: M71, 7x90s (too faint to make out!): NGC6823, 6x90s: NGC6802, 14x90s: All stacked in dss. Louise
