  1. Some on here may remember that several years ago I wrote an article on astronomy for the disabled, I now plan to publish this article along with another I have written titled astronomy from the inside as a small FREE ibook in the hope it can help those who are less able to either take up or continue with their hobby. So where does the help come in? I need a cover image and am hoping that one of thew members will donate an image royalty free, of course you will be credited and if you wish a link to your astrophotography web site will be included along with a link to this site and my local astr
  2. Thanks guys, its 1.25" fit, but I'll put it to one side as I dont want anyone to use it and damage their eyes.
  3. Does anyone have an idea what this prism/diagonal might be used for? It looks like some kind of Herchel wedge, its all solid metal, no plastic at all and was found in my late brothers astronomy gear.
  4. In all honesty your lightweight scope and camera set up screams buy an astrotrac for ultimate portability, you'd even be able to put the whole lot in a rucksack and cycle out to a darker site out of town if you wished.
  5. I've just been shooting the moon tonight with a DSLR & 300 mm lens. my settings where :- Manual mode ISO 400 1/400th second shutter speed F8 I had the VC on, on my lens and was able to hand hold the shots without a problem. Also auto focus works well on my 500D, but oddly better when I use AI servo focus mode rather than one shot. I hope that helps
  6. Ah John has just pointed out something I wasn't aware off, it seems your using the barlow to achieve focus, to use a reducer you would screw it to the nose piece in place of the barlow, but in doing so you may not as john pointed out have enough inward focus to achieve focus.
  7. Thanks guys, its looking lovely at present and I've missed it whilst it was so close to the sun, I'm really looking forward to winter this year
  8. I couldn't resist chasing the moon through the clouds yesterday evening,this shot was taken hand held with an EOS 500D & Tamron SP70-300VC lens shooting through double glazing and from the bed as always I just have to wait for my DSLR adaptor to arrive and I can use my late brothers 80mm to hopefully get some better shots thanks to my heath robinson birding clamp thats mounted on the hanging pole above my bed.
  9. Try to avoid zoom lenses if you can as they can leave reflection artifacts, prime lenses are best, I've had some really good results in the past with a cheap 28mm sigma manual focus lens.on a crop sensor
  10. As said unscrew the barlows lens element from the end, that way you can use it as a short extension tube to enable you to achieve focus. I would also look at getting a screw on focal reducer if the barlow is a 1.25" one, you can pick a 0.5x one from most astromomy retailers. You should be able to push your camera to ISO 1600 before noise becomes a real issue that you cant clean up in post processing, also shoot RAW if you can, doing so gives you a lot more control over the image in post processing.
  11. The QHY5 is also a fantastic little lunar and planetary camera, both in colour and black and white versions. Also having T threads its very versatile connection wise, though you can of course use 1.25" or 2" nose pieces you can also screw it directly to other connectors, such as the rear of the WO's reducers.
  12. I've had both the 9mm and 6mm, lovely eyepiece that's hard to beat at double the money. I actually preferred mine to my radians!! Those two and my 19mm panoptic where always out of the eyepiece case. The early issues where with a spacer that hadn't had its edge blackened, this caused all sorts of glare problems. The early fix was to take it apart and use a marker on it, but it was rectified by the second production run. Well worth the money, new or second hand. Ps I only got rid of mine when I gave up visual astronomy.
  13. Has anyone got the email submission address's for submitting images to astronomy now and the sky at night magazine. I dont have current copies and cant get any at present but have an image I want to submit Thanks
  14. I agree mike but I thought blueastra had the opticstar 130 which has an ST4 port
  15. I would grab a ZS66 or megrez 72 second hand, not only do they work well as a widefield imaging scope, but are also great grab and go's as well as good little guide scopes. I've had my 66 for ages now and wouldnt part with it, even if I did get another refractor. I used to have both it and a 10 inch dob, so used it on the nights I couldnt get the dob out, I was pleasantly surprised by what I could see with it.
  16. I have gone as high as using a 3mm eyepiece with mine, no issues at all. I would agree that its most likely you barlow shifting the focal point, and its well known that the 66 has limited forward focus travel. Theres more info in a review I did here http://stargazerslounge.com/equipment-reviews/57622-william-optics-zs66sd-updated-15th-feb.html
  17. Distant suns is good, very reminiscent of starry night, better still the lite version is free, so give it a try. There are others but some of them are very glitchy and push the phones processor to its limits. I dont know of any red screen software, it would have to be built into any astro app as it can only run one app at a time. Of course you could get some red filter film and just tape it over the screen with a little masking tape. Scetching wise, just get one of the art apps, most have different size brushes.
  18. JMI do one, alternatively you could add a dual speed crayford to the visual back and operate it manually Rother valley optics carry the JMI ones I believe.
  19. It sounds overly complicated to me, I just have an ST4 cable between camera and mount, then the USB from the camera to the laptop running PHD, the mount handset connects via a serial to USB converter and I use redshift 6 for my pointing/remote control of scope.
  20. The QHY5 runs fine on vista as does the capture software, it also works superbly on the CG5GT mount, I use all three. I havent come across the issue with the QHY6 before but I'm sure there must be a solution on the QHY forum somewhere, its not like them to not have a driver that works with PHD. Did you try talking to Bernie at modern astronomy Steve? he's usually up to speed on all things QHY
  21. Forget the tarp, moisture will condense on the inside, run down onto the mount and get in the electrics, you need a decent cover such as the telegizmo 365 series that are waterproof, windproof, breathable so you dont get moisture build up inside and thermally insulated to protect from heat/cold extremes. I left my CG5 out all winter (and a foul one at that) and never had a single issue. The other thing I would suggest is covering screw, bolt and nut heads with some hot melt glue, completely protects them from corrosion and dirt, deters light fingered toe rags and peels of easily if you need a
  22. Something no one has mentioned is that with a goto mount you still need to be able to identify and centre two alignment stars in order for it to work. Goto isnt always the right answer and in your case I think the sky scout would be more beneficial.
  23. Your right Taz, you've been spoilt, and without spending a lot more money on an APO scope and/or a top end set of eyepieces your set up wont compare with what you see through your top end sight. You do also have to make allowances for our dirty atmosphere, which comes into play when you look heavenwards, unlike at ground level and over the short distances you use when shooting. Just keep going at it, and enjoy what you can see. Ian from airgunbbs
