  1. Quite! I don't think the recent spate of good, unseasonal weather helped TBH. I've imaged there a lot before and it's never been that bad! Surprise View used to be an excellent imaging site but I will definitely take your advice - a scoping exercise in Summer could be very enjoyable in its own right!
  2. I managed to get out to my nearest dark site at Surprise View last night for the first time in 2 years for some widefield Orion action. It was not a successful evening - on top of various antisocial "human entertainment", 5 billion lumen headtorches/cycle headlights and a "sheep in wolf's clothing" Corsa that had clearly ram-raided Halfords parking right next to me and leaving the engine running, lights on and blasting out Niche Bassline at high volume, one of my cameras ceased to function and now appears dead - I'm gutted! I managed 50m luminance, 25m Red and 50m HA...? So, to the question - has anyone tried Minninglow Car Park, DE4 2PN for imaging/stargazing? If so, how did you find it? Was it better or worse than my description of Surprise View above? I'm also open to suggestions of other sites - it would be lovely if there was a stargazing friendly campsite, farmers field or similar to use, I'm willing to pay. Thanks! Rich ?
  3. I know this isn't what you asked but I have this camera and use the Orion/Skywatcher 76mm scope rings to secure it. They are a good snug fit.
  4. #1 is a winner, well done Rodd, beautiful image!
  5. I use a variety of focal length camera lenses - 55mm (Super Multi Coated Takumar) 135mm (Jupiter 37A) and 180mm (Nikkor ED180) all manual focus with a Canon adapter. Because I'm a bit short in terms of flange to focal plane distance, I tend to find that infinity focus tends to be around 2/3rds of the focus travel. I have always had very sharp focus with all the lenses at this 'virtual' infinity mark on a 4/3 sensor (like the KAF8300). It may be worth mentioning that all of these lenses focus externally i.e. the lens changes in physical length when focussed. I wonder if IF lenses react differently to incorrect register distance?
  6. +1 for step down rings for an aperture mask
  7. Could be pinched optics, it might be worth checking the tightness of the primary mirror clips. The mirror should be able to move slightly - when tightening the screws, a lot of people put a little bit of thin card inbetween the clip and the mirror, then remove it to leave a very small gap. It may be that the camera picked up the problem but the mk1 eyeball missed it. Always worth checking anyhow.
  8. I use a two powered Startech Industrial USB hubs daisy chained and have two QHY163m cameras, a filter wheel, a PoleMaster and an Orion SSAG camera all plugged into said hubs running down one USB cable without issue. HTH Rich
  9. You'll be fine given the size of the chip, just focus under infinity on the lens.
  10. That's lovely Rodd, you certainly continue to deliver! Great stuff ?
  11. To add to my previous post, I use the SGP Framing and Mosaic wizard and Platesolve2. It really is a joy to be able to enter an accurate rotation figure and see exactly what you're going to get. It also makes multi-session imaging and mosaics a breeze! I'm either at 270/90 (long side of chip parallel to the dovetail) or 360/0 degrees. Once I've used the star trail/slewing technique mentioned by Olly I'll do a quick platesolve to be sure I'm dead on.
  12. I have used this very combo and it works very well - you will have back focus to spare as it only adds 5.5mm. I prefer to have my chip orthogonal to the RA and Dec axes as I find it makes it easier to plan framing and mosaics. I've now sold my Geoptik adapter and have the very rotator pictured in very good condition for sale. If you're interested drop me a PM ? Rich
  13. Great image, well done!
  14. Great bit of kit, I wouldn't want to be without mine now.
  15. That's a great image and I agree with Gorann, the sharpening works!
  16. You're too kind sir, many thanks! Yes, good skies make all the difference with OSC I find - I also suspect that the QHY8L is a good match for the ED80. TBH it was a pig to process though ?
  17. I have had great results from OSC but find that dark skies are a must. A bright target like M31 gave me a good return after 10 X 600s using a SW ED80 with its dedicated FF/FR and a QHY8L. Not sure how this will work with a fixed mount, unless you're planning high gain 'lucky imaging'. I find processing OSC to be just as time consuming as mono, although calibration time is of course reduced due to the lower number of subs. HTH Rich
