    Diagonal for dabling

    Blimey you have to be on the ball when you post a Wanted eh?
  2. That really is very good looking! Agree with Jiggy, would happily have those on my wall.
  3. Just carried out a sidereal test of the SW Star Adventure Pro. According to the mount, one Sidereal day is.... ... 23hrs 56min and 34s! (+- 30s for gaffer tape slippage) Very happy with that result. It also means I'm not very good at polar aligning or balancing my ED72 on it as the last night had quite a bit of slip. I blame myself.

    Before you head in the loft can you give me a range of cost? Not sure how much these things cost used. “One million dollars!!”

    Sounds good depending on the $$.

    Hi Cleetus, preferably 2”
  7. I've a new mini-frac (SW ED72) for imaging but wouldn't mind doing a bit of light visual, so looking for a di-eletctric diagonal on the cheap. Thanks!
  8. Exactly this one but I've not actually used it yet so caveat emptor until i've actually generated some flats with it... https://www.amazon.co.uk/gp/product/B07GJBF4P3/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
  9. That's so pretty! And that's just newt spider vanes causing those lovely spikes?
  10. My cheapo tracing pad flat field generator.
  11. I'm being an idiot. this foam has an "edge" of a set size that goes all around. No reason I can't do away with the edge and cut a larger block to fit. And that I shall!
  12. It seems this Lidl case is a weird size that nobody sells foam for. Might have to convert it in to another case and shell out for something more "standard" Thanks all.
  13. I can't find replacement foam for this disaster! I haven't slept in weeks.
  14. Wow these look amazing. And FLO doing their own branded premium scope is a wonderful thing!
  15. This ^^ more than anything! I did a sharp intake of breath when solar filter was mentioned.
  16. My first (kind of) and so far totally unused frac. Though I only got it on Thursday
  17. This is fantastic! There's so much going on!
  18. How did you get on with them John? Thought about wheeling up my dob as my back isn't getting any younger.
  19. Not for my lovely Fuji X-T2, but I'm leaning toward buying a modded camera just for astro. Good luck! I hope it works out for you.
  20. It's new shopping list time. I'm going to be doing some _modest_ astro pics with my Star Adventurer and a SW ED72 (if they ever get back in stock). Visually, I see a huge difference when using a UHC or OIII filters on my dob. Would getting the 2" versions of the same filters to screw into a flattener and used with an unmodded DSLR be a sensible purchase for nebular in a Bortle 4 sky? Unfortunately I'm not really in a position to try other people's gear as I'm far from the nearest society. cheers.
  21. Hey, I'm thinking of attaching a spare SW finder to a Star Adventure dovetail L bracket which has a 3/8" spigot, or directly to a ball head via an adapter of some sort. Anyone know what that block thing here is? Looks like it would do the job, would attach the finder shoe to that, and then to the ball head. It's not mentioned on the amazon item I found it on. cheers, e.
  22. (Cross post from...elsewhere. Thanks @Davey-T. Stunned by what you guys have been able to achieve with this little gadget) This is my first stab a tracking and stacking using a Star Adventurer, or anything in fact. I've never tracked and stacked before and I'm an imaging noooob. I'm using a Fuji X-T2 mirrorless camera with an adapted vintage Pentax Super Takumar 200mm/f4 at f5.6. ISO 2500. Happy enough with star shape (apart from the aperture blade spikes) so I think my polar alignment is ok. Used a 5litre bottle of water to weigh down the tripod. Obviously the North America Nebula. (Well, not that obvious) Bortle 4/5 back garden, Moon not yet risen. 15 lights at 165s (best I could get with those cloud things), 10 darks and 10 flats. Flats shot by holding the camera to a white screen on my phone. Stacked with DSS and processed in PS and Astronomy Tools Action set using AstroBackyard's methods here. Transparency wasn't the best, i think I was shooting through thin cloud most of the time. To be honest I'm not delighted with it: The nebula is a bit dim eh? Very low contrast on the nebulosity. I don't think I could go much longer untracked than 2'30" or 3' on the Star Adventurer. There's a red cast. Stars that should be bluer all seem to be a bit reddish. Not sure why. White balance? I think I probably had it on auto but I was shooting raw so would think I'd be able to deal with that. It's a bit noisy. Big pointy stars. What I think I need to do to improve it: To increase nebula contrast, I'm thinking of getting myself an old 600d off fleebay and getting it modded. Maybe one day getting an h-alpha clip filter for it. It would leave my gorgeous Fuji X-T2 to have normal human being settings, and not weird astro settings. Redness? I don't know. It doesn't look very natural to me. Noisy? More subs I guess. I could drop the ISO but then I'd need have longer subs, and the SA won't be up for it. Spiky big stars. I have a stop down ring that I forgot to use. Note: Don't forget to use it. Does this make sense? Any further advice on improvements i could make would be hugely appreciated. (I'm a budget astrophotographer if you hadn't guessed) Thanks all!
