  1. looks good! i've nearly finished one using a FYSETC E4 board for my Vixen GP mount. Very impressed with the whole thing. I'm finding the hardest bit is mounting it inside a case with cable plugs etc!
  2. Not many clear nights these days it seems! This was taken on the 10th Jan. 47x 1 minute exposures at ISO 800 on modified Canon 60D plus 50mm lens with an Altair triband clip-in filter. Camera was on a Vixen GP mount with an Onstep setup. Processed in Astro Pixel Processor.
  3. finally a clear (ish) night so gave the onstep on GP mount another trial with a better PA (2.4 arc-min) It's doing really well IMHO (this a C8 with a 0.63x reducer and a Canon 60D) guiding accuracy seems to be around 0.63" going as low as 0.42" at one point! onstep-guiding291223.tiff
  4. yes - really easy. basic skills will be good enough!
  5. I can confirm control of the onstep is good via Astro Photography Tool and PHD2. once a couple of platesolves and syncs have been done, it's very accurate at slewing to what you want. The guiding accuracy was not great, but it was really poor seeing, i have a polar alignement error of over a degree and had a fully loaded C8 on the GP mount (way over what you should have on a GP for photos). Although the guiding wasn't great it was a massive improvment over the GP mount with the SS2K on it, which basicallly wouldn't guide at all. I guess the SS2K motors and using spur gears compared to the belt drive and modern steppers for the onstep have helped here. I think I can get the guiding better with some decent seeing, a proper PA and may a bit more time spent on balancing. Certainly the poor guiding isn't down to the onstep, it's the amount of gear I have on the GP. We will see.......
  6. hi bought this for my vixen GP mount and it works really well. looks like there's an eq3 version. they are quite responsive to email questions I've found. https://www.terransindustry.com/en-gb/collections/onstep-v4-kit/products/skywatcher-eq3?variant=42521248596161
  7. thanks guys, i might be able to stretch to a samyang 14mm which looks pretty good, looks like I could pick one up for 180 ish. 300 too much for the 135 as I'm saving up for other more expensive stuff!!! yes the sponge is getting rinsed haha a nifty fifty does look good but think it turns into an nifty eighty on an aps-c sensor.
  8. After some recommendations please..... I've just bought a astro-modded Canon 60D body. I don't have any lenses for it. Most of the camera's time will be on the back of a telescope but I might want to use it for very wide field or even "normal" daytime photography! I don't have a huge budget (up to £150 ish ) and happy to buy second hand. I think it needs to be an EF mount as I have a quad-band clip-in filter and EF-S lens protude backwards into the camera body and will hit the filter. What lens would you buy? thanks in advance 🙂
  9. my belt-modded and regreased etc neq6 nearly always guides below 0.5" regular periods in the 0.3's. best ever was 0.22" which I had to do a screen grab of after my jaw had dropped..... guiding022.tiff
  10. can recommend this: https://culturehustle.com/products/black-4-0 as long you are not associated with Anish Kapoor!
  11. thank you, I know I'm going to enjoy reading those posts
  12. looks like it clouded over at 03:04 and never cleared up. what time was your flip?
  13. kudos! wow that is some setup Windjammer! 2 filter wheels in series is it? And a drill chuck in there?
  14. hi, my onstep has pulleys with an offset which might help?
  15. and if you're struggling for backfocus, it can be handy to not have to accomodate the OAG. but still prefer the oag for weight minimisation and keeping that weight as near as possible to the centre of rotation - to help with guiding performance. so far so good !!
