  1. Hi all I've been converting my NEQ6 to belt drive using the Rowan kit, and cleaning and regreasing for the first time. All the bearings appeared ok and still full of grease, so I only added grease to the carefully-cleaned worm gears. Having reassembled and adjusted the backlash, everything seemed fine until testing through a complete revolution of each axis. RA is sticking and stopping the motor at just one point on a full rotation of the mount, so I'm thinking the brass worm gear must be the culprit. I tried loosening off the backlash and also the steel worm, but it was still sticking. Any ideas where I should look? I now have as secondary issue in that in trying to strip the RA axis down again to have a deeper look, one of the bearings is stuck fast and won't allow the RA shaft to come out . Thanks Nick
  2. Hi I’m struggling to get started in Nebulosity 4. I’ve followed the tutorials carefully but am struggling to reveal any Nebulosity in my images with ‘Levels / power stretch’ (again, following the tutorials carefully and using low power, etc). The images I’m trying to process are around 30 x 480 sec subs of the Rosette Nebula and 40 x 120 sec subs of the Pleiades. Both using an FLT110 refractor at F7 and an unmodded Canon 5D3 (I captured RAW + JPEG). In both sets of subs, I can see nebulosity in the raw subs but it disappears after stacking and power stretching doesn’t reveal anything. If I stack the JPEGs, the nebulosity is there. While capturing, the histogram peaks were around 30-40% for each colour channel. I have plenty of darks, bias, flats, etc. Any ideas to get me started? Thanks! Nick
  3. Completely agree with the above. The software is a joy to use and you feel as though you are achieving a lot with your time.
  4. Hi Mark. It was the shape of the extension tube that meant the camera and eyepieces did not go in the same distance. Using a different tube solved the problem. I'm not sure about reflex camera control.
  5. I'm getting the parts together to build an allsky camera using a DMK31. I've got a 6 inch acrylic dome from an underwater camera enclosure which I'm mounting on a waterproof plastic enclosure. I managed to bag a bargain on ebay with a Fujinon F1 lens for about £20. The bit I'm struggling with is how to approach dew control. The enclosure I have is quite big (260x185x125) so I have room for options. Should I use a dew tape? If so, where should I put it? The only other thing I can think off it some sort of small DC fan heater, but can't find anything appropriate.
  6. I went for a Skyshed Pod in 2011 and love it. I considered a roll-off roof, but didn't really have space and my wife didn't want another wooden structure next to my workshop shed. I considered the pulsar, but didn't want to have to tackle motorising the dome for imaging. I had a good look at another Pod owner's setup which helped make the decision. It's so fast to get up and running, and everything stays clean and dry in the plastic environment. I have 4 storage bays, which works well (though I haven't quite figured how to best store all the scope and camera cases). For most imaging sessions, I just need to go out and move the dome round every hour or two. Interestingly, I've never had a dew problem either (all my dew heaters are still unused). Imaging at the zenith is a problem, so I added a zenith table last year but have only needed to use it a couple of times. I don't find it too noisy to slide on and off. I am conscious of noise as our gardens are small - I did change my mount to reduce noise! I'm in the Cambridge area if anyone wants to view a Pod. Nick
  7. My garden is solid clay and changes from boggy to completely dry throughout the year. I put a 2 foot cube of concrete in as the pier base and I haven't seen any movement in 3 years.
  8. My lovely wife treated me to a mono camera for Christmas and these are my first efforts. One was taken using a WO FLT110 on 15th Jan, the other using a CPC925 on 20th Jan. I did the stacking in AutoStakkert (Registax wouldn't open the files) which was a joy to use, and tried a bit of wavelet processing in Registax. Any advice for improving next time always appreciated! Nick
  9. Yes, it is the OSC version. This image was with a William Optics FLT 110 with TMB flattener. I've been struggling with the learning curve of mono (Atik 314L) and wanted to try OSC. The near-live appealed so that I can learn during the session. I'm having fun so far - just watching an image of M81 evolve as I type.
  10. Here's my first go at imaging using the new Atik Infinity. It's a real joy to use. My processing is a bit crude, so will have another go.
  11. I was setting exposure above 30 fps, e.g. 1/100 sec. IC Capture is showing 30 fps as an option, but won't receive frames at more than 15.
  12. My DMK31 will only deliver images at 15 fps or lower - it will not deliver images at 30 fps. I've tried numerous USB cables and several PCs across USB 2 and 3, including via a powered USB hub. Any ideas? Thanks Nick
  13. Hi all A 2006 Pentium D (home built) desktop PC has been running my Skyshed Pod for the last few years. I've always left it turned on (unless updates, etc shut it down) on the basis that it can't hurt to have a little heat in there to keep itself dry. It's had a few problems recently, which I now know is faulty memory (or memory slot). I do have a Sony touchscreen laptop/tablet hybrid which has been relegated to Minecraft duties. Any thoughts on benefits of a laptop vs fixing up the PC / frost heater? Nick
  14. Hi all I'm still a novice imager that struggles for time, so enjoy taking kit with me on camping holidays. However, I've just downsized from a big touring caravan to a Ford Tourneo (Transit) camper and need to travel light (three of us and a dog). So, I'm wondering what the best kit to take would be, and ideas for storing. Everything I have is in big flight cases (apart from the mount). I'm prepared to get a smaller mount if that is the consensus. My first trip will be to Kelling Heath over the August new moon. I'm thinking maybe go widefield (which I've never done) to get some good stuff in the bag. Here's the main kit I have: 80mm Zenithstar II ED WO FLT 110 Triplet Lunt 60mm solar CPC925 (deforked) Ioptron IEQ45 with portable pier (head is in a padded case) Photo tripod Atik 314L+filter wheel EOS 5D (inc wide angles and APO F2.8 70-200) Mono Imaging Source Various standalone or PC-based guiders Herschel Wedge So, main thoughts are around which scopes (or just camera and lenses), mount and ways to carry the scopes without the big flight cases. Thanks! Nick
