  1. 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.
  2. 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.
  3. 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.
  4. (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!
  5. Hi all, (whoa it's been ages since i've been here. ) This is my first stab a tracking and stacking using a Star Adventurer, or anything in fact. I've never tracked and stacked before.

  6. redid using the workflow I spent, ooh, hours working out. The moon looks a bit less mouldy now yet still can see some colours. . Thanks so much for the input @johnfosteruk
  7. First clear night in yonks and it's a blooming full moon. So flat and glary. Determined to actually get the scope out though. 16 still RAW images from Fuji X-T2 on an untracked 10" dob. Did pre-processing in Lightroom to get the saturation up, exported tiffs. PIPP to roughly line up and produce and AVI, then much playing in Registax as I'd never used it before. Apparently a full moon isn't so flat.
  8. I've been looking for a cheapo solution to attach the cheap and ubiquitous red-dot finder to my Celestron 20x80 but didn't like the official clip thing that Celestron sells. Bad reviews complaining of it easily snapping, and to me, overpriced. After much research and counting of pennies, I went for this all steel, no-snap solution, costing a whopping £6.90 (with free shipping). From the top: 1 x 20mm Dovetail to 11mm Rail adapter. £2.69 with free shipping. https://www.aliexpress.com/item/20mm-Dovetail-to-11mm-Rail-Mount-Weaver-Picatinny-Rail-Scope-Mount-Rail-SA089-P15/32800225228.html?spm=a2g0s.9042311.0.0.b0d14c4dzyuqK1 1 x Picatinny/Weaver 20mm Rail Base Adapter (used to attach scopes to rifle barrels) . £5.11 with free shipping https://www.aliexpress.com/item/20mm-Picatinny-Weaver-Rail-Mount-Base-Adapter-Tactical-Hunting-Rifle-Gun-Scope-Mount-Converter-Laser-Sight/32792605686.html?spm=a2g0s.9042311.0.0.b0d14c4dzyuqK1 1 x bit of thick plastic to act as a shim. Anything will do.
  9. It was an amazing moon. A tiny break in the clouds for us in Ireland, just enough to grab this featuring J Herschel, with my iPhone (with a small amount of help from a 10" dob). That is JH at 4 o'clock isn't it? Gassendi at 150x was amazing. The detail from the crater floor was gobsmacking.
  10. It's been a fantastic month for Mercury. Last year I went to great lengths (drove a bit) to find a horizon low enough to see Mercury for my first time. This year...it's just there.
  11. I had this exact same problem using a similar scope. With a finder scope it would help as you have less magnification. I find with the charts in S&Ts Pocket Sky Atlas, and really paying attention to the layout of the stars in the chart against what you see in a finder scope, hopping around gets easier and you'll never have to cheat and get a GoTo scope.
  12. I've spent wasted money on a cheap Seben laser collimator...which needed collimating. I then wasted so much time trying to get it perfect. I can't understand why anyone would get one. The Howie Glutter is probably a damn fine instrument, but I can think of better things to spend my money on. I've splashed out on the very fancy red anodised Cheshire from FLO and and a nice collimation cap. Very happy with the results, though it does take a bit more effort than a laser. https://www.firstlightoptics.com/other-collimation-tools/premium-cheshire-collimating-eyepiece.html
