  1. What scope to get?

    I recommend seeing them in person if you can, I've got the vx 8 and it's a formidable beast for a first scope. But if you know what you're getting into it's a great telescope, just know that your expenditure won't stop with just the telescope and mount. There are a multitude of extras and aids to consider as well as a wide array of eyepieces. First will be a decent power supply, mains if your close to your house or a power tank if you plan on going out and about
  2. full spectrum camera and filters

    OWB filters take away some of the red like the camera's original filters did, Astronomik do clip in filters for different cameras. You could set a custom white balance to correct for the red tint if that's available for daytime shots and switch back to normal for astro work, you need to experiment to find out how with your Sony as I'm only familiar with canon. The uv/ir filter will be fine for the present whilst your still getting to grips with your equipment.
  3. full spectrum camera and filters

    Will full spectrum cameras you can't achieve focus without some sort of filter, the spectrum is too broad. If violet is in focus the far red shifts out of focus due to the difference in wavelengths. The UV/Ir filter is so that you can achieve focus on nighttime targets such as nebula, you can use it during the day but images will appear to have a red tint as the camera is more sensitive to red then it used to be. The full spectrum mod removes the Ir cut filters which are less selective than astronomy filters and remove somewhere like 70% of light emitted in H-alpha which is what many nebulae are. The infra-red is useful for lunar and planetary shots using either an Ir pass filter or a long-pass red filter, these cut the blue end of the spectrum so that you can still achieve focus. Just note that for pictures taken with an Ir pass filter you won't be able to focus though the viewfinder but you can through a screen. To use your camera as normal during the day you would use an original white balance filter (OWB), or you can reduce the red during processing of images in Photoshop or the like so long as you take your pictures in raw mode.
  4. 1st ever picture

    Starting out is the best, the speed at which you'll advance is terrific. I'm into my second year of imaging and I'm now getting some cracking pics. But as always with this hobby everyday is a school day
  5. First telescope thoughts.

    In terms of working out magnifications and such try this https://astronomy.tools/calculators/field_of_view/
  6. When I built my battery box I was told that leisure batteries are better as they deliver a more constant voltage during discharge and can go below 50% without being damaged. Jump starters and the like are designed for shorter periods of high output. That being said they are cheaper so can be replaced more often anyway
  7. Baader 2" 7nm Ha filter

    Yes but best if your DSLR is astromodified. Here is the horsehead with that very filter taken with my canon 700d
  8. Markarian's Chain

    They are 10 minute subs but my guiding was spot on and should have done 15. Didn't swing round until nearly 2am so I was pretty tired to be out so long what with getting up for work at 5 the previous morning. Bit more data and it'll be a treat. Of course it looks like a cracking piece of sky so I'm thinking of a nice big mosaic with a longer fl to get better detail. But now I've said that there's bound to be clouds until April šŸ˜‚
  9. Markarian's Chain

    Had a go at Markarian's Chain on Thursday night. Should have done longer subs but I'm pretty pleased with what I got
  10. Another Rosette Nebula

    Looks like a good number of people were grabbing data on the rosette last night but here's my first go at it on my SW ED80 12x 600s with a Baader UHC Filter 20 Flats / 30 Bias 5 Darks (The darks library is small but slowly increasing)
  11. Target recommendation

    You can never go wrong with M42
  12. Outreach Laser Pointer

    Rother Valley optics has a 5mW green laser for about Ā£30. I find that these pointers tend to drain batteries even when not being used, just something to be aware of.
  13. Deep sky imaging showcase 2017

    Orion Nebula (M42) East Veil Nebula (NGC 6960)
  14. Moving from visual to imaging

    You don't need to get the st80 as a guidescope. You can mount a webcam or a small sensor astro camera onto your finder with an adapter. This reduces the overall weight which is the key with dso work. Planets really want long focal lengths so Maks or Scts are best for those.
  15. Not sure about breaking up a galaxy but there are several simulations showing what we think will happen when the Milky Way and Andromeda collide. They show both galaxies shedding large numbers of stars as the two black holes slingshot each other. Though none of us will be around to see it unfortunately
