    Celestron AVX

    Are you dead set on an Avx? Why not consider the skywatcher heq5 pro as an extension tube is already made for it. The heq5 also has a slightly higher payload and can be upgraded with a belt mod for even more accurate tracking. Flo even sell it prefitted if you want it from the off

    Celestron AVX Mount.

    I love my AVX and get on quite well with it. I didn't get on with the polar scope at all, some weird poses and contortions meant that polar alignment was a lengthy and often painful experience and have opted for QHY's polemaster instead of struggling. In terms of mods I upgraded to the ADM saddle and haven't regretted a penny on it, no marred dovetails +1 to the balancing issue, that can be a nuisance but you get used to the feel of it

    Controling dew, help?

    I have a deep cycle battery hooked up to a distribution board I made. Went with Phono plugs and sockets with variable resistors so I can lower the current. But you can choose your own plugs and such to suit your power supply. Dew control is top right of my board

    Controling dew, help?

    I have an 8" edge and made my own dew heater strap with nichrome wire. I made it to draw up to 1amp and that's more than sufficient to keep the dew off with a standard shield. HTH Clear skies
  5. Just a quick fyi on the reducer, it reduces the amount of backfocus from 133mm without to 105mm with it. Just something to keep in mind planning your setup
  6. The choice of adapting your existing finder or buying all new gear is entirely up to how you want to allocate your budget, as I had my finder just lying around I adapted mine and bought the baader guidescope mounting. This just slots into a synta style base. I also made my own dew heater as I kept getting dew after a while. Had the Evoguide been released a few months earlier I would have had that and used it as a travel scope too, but that's the way things go, mine works well as it is so not worth laying extra cash out to have a pretty one. Who can see it in the dark after all?
  7. I use an Altair Astro Lightwave 0.8x reducer/flattener with my ED80 and that works a treat, take a look at those. With your guiding question, I use a 50mm finder as my guidescope and it corrects the AVX a treat when I'm imaging with my ED80.
  8. Someone else with far more experience will no doubt correct me but as I've previously been tempted to look at the hyperstar route and don't think it's the best way to go. The issues that I heard of with it were that with the focal ratio being so fast focusing has to absolutely spot on. Given sct's predilection for mirror flop this can be difficult to achieve. There were questions as I recall regarding the size of the imaging circle with some vignetting. If your determined to image at very small F numbers given you've said you have an NEQ6, you might want to look at Celestron's Rowe Ackermann Astrograph. That has a larger aperture and is designed to operate at F2.2 instead of being modified. Better spending money and getting it right than forcing the wrong equipment. You'll get some better advice in the not too distant future I'm sure but something for you to look into whilst you wait.
  9. For dso's your better off with a ed80 or something similar, the mak and Schmidt have long focal lengths which make guiding and polar alignment absolutely critical to any imaging. The difference between the mak and the Schmidt is that the mak has a concave corrector plate in the front which makes it heavy. Schmidts have a thinner flat corrector but use an additional flattener to make a flat field. Another point is both the mak and the Schmidt are prone to dew problems and have long cool down times.

    old or new?

    Flo have an opened box heq5 pro with £50 knocked off in the offers section

    want to change my setup advise please!

    I have had an 8" Newtonian on my Avx which is similar to the heq5 in terms of capability and capacity. It's an unwieldy beast on a non permanent setup as it catches too much wind for the mount to cope with. My ed80 is used far more and as previously stated is quite resistant to wind effects (Though not immune I should say). The wider fov is quite helpful on dso's which are surprising large once you get going. Never once regretted getting the ed80 it's a remarkably able scope, focusser aside it's terrific

    A friday night Markarian's Chain

    When I've done it in the past I've switched the file output from raw to regular images for daytime work. This is an easy setting to switch on canon cameras not sure about Nikon. You can have a single set of bias frames and reuse them for different pictures. You only really need to do flats each time to get rid of any dust bunnies in the imaging chain and differing illumination levels over the sensor.

    I've found that the disparity in image sizes when using my canon happens when I've switched between Raw files as the output to jpegs. The raw files being those few pixels larger. Great shot too
  14. With regards to your idea of having an 8" Newtonian on your Avx I would suggest caution. Whilst the mount can manage the weight, the slightest gust of wind moves it around quite a bit meaning that you'll be limiting your viewing opportunities to only perfect conditions

    Wanted dustcap for polar scope

    I have an ADM one from the knob kit for my AVX, don't know what diameter cap you need but they can't be all that different. I measure 34mm with the rubber o-ring
