  1. Despite the murk, 46P was actually naked eye (with a hint of averted vision) tonight. Here it is headed into Taurus: brightest close star is t Tau. I'll be out on 16th for the close pass to the Pleiades.
  2. I periodically have a go at imaging this bright spot in the broader Merope reflection nebula in the Pleiades. This is 13 x 30s C9.25 w reducer / Atik460/ AZEQ6. Accidentally binned 2x2 - although that's probably all the seeing was worth. Laplacian sharpening in Nebulosity (software). Sure NASA/HST are grateful I've verified the main structural features their effort picked out. Tim
  3. From the Malvern Ridge near Black Hill this morning. These are with 100-400L on Canon 7D. Had no luck closer in with the camera attached to an ETX90 tube. Too low / distorted for any Jupiter detail, but can just make out a couple of satellites here.
  4. Quite pleased with this for only 40 mins luminance and given it's so tiny (5' x 3' or so). A bit of structure in dust lane. Structure-wise I've seen worse from C14 and 16" instruments; must have had a spot of seeing. C9.25 w. reducer / Atik 460 / AZEQ6 8 x 300s. Incidentally, almost exactly two years the AZEQ6 has been outside continuously in all weathers with only a John Lewis bag (and later a Green Witch cover) to protect it; bit of rust on the chrome screws, otherwise no probs ! Tim
  5. Thanks. Bit nerve-wracking setting up for it. You don't get a second go!
  6. Just as a post-script to this, I did today decide to return the scope to the dealer, who after I'd shared the wisdom of this forum (and some photos from Etsy / Ebay showing the same item sometimes even available made new to order !!) returned my hard-earned. So another educated dealer. I don't think anyone was acting in bad faith here, and I've learnt a lot about the scientific instrument reproduction and/or fake business.
  7. Okay. With Philj's and Cosmic Geoff's help, and further research, I've convinced myself it's a repro. So thank you guys. Disappointing from the romantic historical associations point of view, but polished up (which I can now shamelessly do!) it will make a nice piece of interior decor in the garden room :-) Interesting though how many apparently reputable (and accredited in some cases) antique dealers are pushing these as original. There's one out there without a doubt exactly the same as this, but polished up with new leather at a ticket price over £1200. I found one auction house lis
  8. I also wondered if these were made with rolled and soldered tubes - for which I think B&C were famous; I certainly have a drawtube made that way from Fullerscopes using the old B&C kit. Or were they extruded from bored/cast/machined tube? No obvious solder seams on this example.
  9. Thanks for the comments guys. Yes, I guess it could well be a repro; for £75 though I'm happy to keep as a decorative piece. Anything substantive I'd normally research to the n'th degree before purchase. Of course I'll have to now research this one to double-death just for the sake of knowing !! One thing I'm pretty sure of, there are a few of these out there that look exactly the same. The weight of this one btw is 1.1 kg. I wonder how that compares with your similar example philj? Also, the fit of the tubes is very good - perhaps too good? I'll let you know what I come up with after
  10. Okay, so it's not an astronomical telescope as such, but it could be pointed at the sky, and it is the only telescope I have that actually...telescopes! I picked this up today in a local antique shop for less than the price of a NB filter, and it's just nice to hold such an iconic and well-made collection of brass tubing and glass. Made by the illustrious Broadhurst & Clarkson company (later bought up by Dudley Fuller in the 1970s) at Farringdon Road, some of these had stitched leather cladding - missing from this if ever present - and existed as a military variant as part of a WWII snip
  11. It's difficult to get a sense of scale in this astronomy game; but we try. So here are 8 pics of the ISS passing between Vega and Epsilon Lyra last night - which is a second's worth of my Canon 7D firing off as fast as it can. The background is a single 30 second tracked exposure for a bit of context. Details: Esprit 100 prime focus/Canon 7D:1/1000s ISO1600 +30s background. The trick if you want to try this is to use planetarium software to find out exactly when the ISS will be near a bright object, then pre-align and focus on or near that object, then wait for the ISS to appear in the f
  12. Today is really the day for this comet, with Owl Nebula and M108 coming into view, but the forecast looked dicey last night, so I thought I'd bag it. An Atik 16200 would be nice about now, but this with the Canon 7D will have to do for now. (Esprit100/AZEQ6/Canon &D. 90s x 14). Suspect I may just get the three objects in frame tonight (if it clears) - may be close thing. Tim
  13. It's quite a special object at any focal length. I've tried with my Esprit 100, but the SCT is about right if the seeing plays nice. This image is very much seeing limited; those central stars would sharpen up in the right conditions.
  14. Not posted for a bit, but I did recently capture some half way respectable OIII data for the Crab, which I've here combined with some Ha/S/Lum data from last year - some of it reprocessed. This is with the C9.25 with reducer and Atik 460, which I think gives a nice image scale for this object if you want to see the pulsar properly and a bit of structure (but don't bother at this scale without an off-axis-guider). Colourful Ha(red)/S(green)/O(blue) palette :-). (About 12 hours all in) Tim
