  1. Tis indeed the second one from iTelescope. They get things nice and oriented. I actually prefer the data from my RC6 though, despite the gradient I can see after posting. Just goes to show how much the $$$ racks up to get those last few % improvements and how well you can get things working with a scope that costs less than a single filter in the iTelescope setup.
  2. Been meaning to do this for a while. Not exactly a like for like, given the home scope was just over 6 hours and the iTelescope scope had just under 3 with a bit of a few missing Green subs (half the number of B,R). Home scope: Altair Astro RC6, HEQ5, Atik 460ex. 0.69 arc-sec/pixel iTelescope 21 : Planewave 17CDK, Planewave Ascension 200HR, FLI PL6063E, 0.96 arc-sec/pixel Which is which?
  3. I think you are probably right. Means I can get exactly right equipment combo per application as opposed to a do it all single rig which might need to compromise somewhere
  4. Has anyone seen one of these up close or even in action? Rotarion Tempted to utilize something like this for a combined spectrograph/imaging setup as opposed to a multi scope operation.
  5. I have the RC6 and run at native F9 and I use an Atik 414ex (equivalent to your 314L and an Atik 460ex. Great little setup for me.
  6. Been a long time since I had the opportunity to spend a bit of time gathering data. Native F9 with the little RC6 on my HEQ5 with an Atik 460ex for an LRGB image of around 12 hours total. 2x2 binned RGB. Multiple sessions and a lot of discarded subs due to rustiness and those pesky high clouds blowing over, but more than happy with end result. Nice to be back processing my own data.
  7. I bought a second hand ST80 in my early days of astronomy and it still gets regular usage as a guide scope as I have moved to focus more on astrophotography. Not many bargains in astronomy, but this scope is one of them because it is so flexible.
  8. For those rebels who actually look through their refractors, and to those who have an aversion to clutter, I suggest you look away now. A kind of dual imaging setup, one which is based on flexibility than both scopes imaging at once. Each one can guide the other, giving me options in one setup.
  9. Isolation of the flooring itself if possible sounds like a good idea, but simply building pier on the existing base is how I am going to proceed - thanks.
  10. I would scour the classifieds for the older generation ccd cameras and filters (assuming you want to go mono). This will get you started at that budget. Cameras like the Atik 314L for example AstroBuy Sell: Atik 314L colour
  11. Something I found in my experience in this hobby is that it is worth finding a configuration that works and sticking with it. This comes from having a setup and tweaking over and over again over the course of session after session to fine tune how it works and behaves. Having a scope which requires basically disassembly to convert between use cases breaks this and sets you back to square one each time and is the classic case of jack of all trades, master of none. I don't doubt the Edge 8 is awesome in whatever configuration it is capable of, but that will come from being in that configuration for an extended period of time, making the flexibility of that scope a little of a double edged sword. If I was to buy one of these scopes, it would be for a particular purpose, not because it could in theory do many things.
  12. OAGs are more fiddly to get working, sometimes require adjustments to the imaging train to get guide stars and overall I have found to be more than awkward to use. For the multiple scope use case you mention, I use the same ST80 guidescope and guidecam and put it on a whole variety of other scopes and it just works. There are loads of stars to choose from, I can choose whatever framerate I need and never have to rotate things just to make it work. Astroimaging is hard, and the simpler things are, the more likely it is to result in usable images, and starting out, its all about minimising things that can go wrong. I am not saying OAGs can't work with small refractors, but they are not required, there is no mirror shift to worry about which is the main reason OAGs are used and you can get good guiding with a less complex setup. Be nice to yourself and get things working to the point where you don't have to worry about them.
  13. Hi Rob, To my eyes, its got better contrast, tighter stars and just has an overall crisper feel to the views. Its way more tunnel visioned given the different optical characteristics. The 250px is brighter with the huge aperture advantage, and I use it more than the Mewlon as its a Dob, and I have yet to get a simple AltAz for the Mewlon, but whether its imperfect collimation or something else with the 250px, I just think the views through the Mewlon do it for me. My first light report still holds true : Mewlon First Light
  14. Leave off axis guiding for another day. For an 80mm scope, use a finder guider or a little guide scope.
