  1. Been processing some old data from last year while the clouds were about. This is a LRGB+Ha image, 12x240s L, 12x120s RGB and 12x300s Ha. Processed in PixInsight and PShop. Esprit 150 & SX-H16 camera.
  2. Has anyone ever found an alternative tripod/pillar mount for the Evolution 9.25 heavy duty tripod that can hold the Evolution motor head and OTA? The motor head has three threaded holes at 120 deg around the edge, and a central hole for a locating pin on the tripod base. The tripod base has three captured screws that screw into the motor base, and a central locating pin. The nearest I’ve found is a Baader adapter plate that fits on a Baader metal t-pod tripod. The reason I ask is that my existing tripod base is getting heavy for me, and I’m looking to see if there are any lighter options that can handle the 9.25.
  3. That might limit the trailing on a single sub, but what about the relative trailing in a stack of subs over an hour or so?
  4. How do you deal with field rotation with this scope?
  5. I think the problem is that most software I’ve tried (PShop, etc) do not accept FIT images, so I’m trying to find something that does.
  6. A typical all-Sky imaging sessions leads me with 1000-2000 FIT images. Is there any software that creates star trails from FIT images? Or can auto detect meteor FIT images? (Not sure if this question should be here or in software)
  7. I bought one of these from Amazon for power/current measurement. It comes with bare ends so I put a power plug (male/female) on each end and just put it in series with with the dew straps for measurement.

  8. What would be the best filter choice for Jupiter/Mars viewing with a Celestron 9.25” + Baader Hyperion 8/24 mm eyepiece?
  9. I have a first gen Evolution. I've noticed recently that the Celestron logo displays a fast blink when switched on, either running from the internal battery or external power. According to the manual this indicates an error, but gives no indication as to what the error is (-Contact Celestron!). However, everything appears to be working normally, either with the HC or via Sky Portal on an ipad, and it has been for some time. The current firmware versions are HC: NXS 5.31.9200, MC: 7.17.0098, and the last time I update was a year or two ago. Anybody any ideas on what the error could be?
  10. I'm looking to find a battery as a remote option for an all-sky camera (12V, 1A, 1.5A peak, camera & heater, etc). I've noticed that most of the astro shops only seem to offer the Celestron battery options. I'm sure there used to be a lot more options offered some time ago. I'm looking for a reliable Li solution that will run the camera for around 8 hours, so maybe 8-12 Ah (although ratings from manufacturers may be optimistic, so perhaps a little more). Any suggestions?
  11. The dew shield on my Esprit 150 only extends about 12cm from the lens. Should it go further?
  12. The tripod leg clamp on my Evolution 9.25 broke, but I managed to get a replacement. However, I’m not sure how you get the tripod leg cover off to allow the new bracket to slide on. I’ve undone the grub screws but it still won’t budge. Does anyone know if the cover is screwed or glued on, or just very stiff?
  13. I’d just like to say that I have owned starlight xpress cameras for many years and have been very pleased with them. On the odd occasion that I have needed some service I have received exemplary service and advice from the company. I currently own a SXVH16, SXVH18, SXVM25C and an SX Lodestar, with my rig currently using the 16 and the lodestar. I would have no hesitation in buying new cameras from the company, and I hope they have a long and successful future supported by the UK astronomy community.
  14. It’s a bit like art, some people appreciate it and some don’t. There isn’t a right answer, but everyone is entitled to their view, likes and dislikes.
  15. I think one of the major reasons is as a field flattener for imaging. Imaging Newtonians or edge variants have optics before the camera to flatten the image. These are not present in standard SCTs so the reducers give the flat field.
