  1. Here's an updated shot. Clear skies again last night, so after finishing work at midnight I went out just to get this image. 47 x 60seconds @ ISO1600 on a Star Adventurer. Same lens and camera as before.
  2. Well, I'm impressed with the Z6. I purchased the Z50 back in July and recently upgraded to the Z6 plus I got the Nikkor 50mm F1.8 S lens (I don't only do astro stuff). Last night I was out until 4:15am to get a shot I planned, and wow. My favourite photo so far. Yes, I had to take a separate shot of the Milky Way, but it's where it should be. Can't wait to do more 'closer' images of our galaxy's core without being interrupted by clouds.
  3. In my short experience shooting with a SA and Nikon Z50 with the 50-250mm kit lens, flats are more important than darks. In fact I've stopped doing dark frames altogether and I've been getting great results. I'm looking to get the WO ZS61, so hopefully that will be a improvement over the kit zoom lens.
  4. I just sold a Samyang 14mm f2.8 lens for this reason, coma. Even stopping it down to f4 didn't fix it. I suggest stopping it down and see if it goes away, if not, don't use it for astrophotography. Even though I got a good shot (see photo), zooming in you can see the star issues.
  5. I've been having good results with my kit zoom lens (Nikon Z50, 50-250mm F4.5-6.3). I'm fairly new to this, so I'm excited to get a dedicated astro lens. Would something like the ZenithStar 61 be really good?
  6. Hi Graham, and thanks. 1. That is a Benro Mach3 Alum 4 section (around £120). I don't know about the Manfrotto, so best to do a specs comparison. 2. My Nikon Z50 can't use an intervalometer, and the camera setting max out at 30seconds and 9 exposures, so I use a spare android phone attached to the tripod using a cheap cycle mount, tether it to the camera via USB and use qDslrDashboard app as an intervalometer. I could use the camera's wifi to connect to the phone, but it's a bit unreliable and uses more battery (which the little Z50 uses after 2-3hours of non-stop shooting). This way
  7. Just done my 2 best images with a SA now that I have a car and can get to a Bortle 3 site. Had the SA since October, but only recently been able to use it properly due to work and weather. No guiding. Lights and flats only. Nikon Z50 (not astro-modded), 50-250mm F4.5-6.3 kit lens 90second exposures @ ISO1600 M31, 36 light frames. Rosette Nebula, 70-80 Light frames.
  8. You're welcome and thank you. It seems that darks and bias frames are only more necessary when you really pump up the ISO and for dedicated astro cameras taking 3+min exposures. Flats are an absolutely must have. My Nikon Z50 has limited battery life and I've found that not taking darks has made little difference, if any. Plus there are no Z50 spare batteries in stock anywhere at the moment, and they're £50-60 a pop. I've only just purchased a car, after 6 years without one, to enable me to travel to darker areas. I used to lug this kit around on my electric bicycle, but that can only ge
  9. Here's a shot of my setup. Nikon Z50, 50-250mm kit lens F4.4-F6.3 Star Adventurer Benro Mach3 Tripod Spare mobile phone using qDslrDashboard (USB tethered), a cheapo cycle mount to attach it to the tripod. COOWOO lens warmer 2 USB power banks (1 to power the star tracker, 1 for the lens warmer)
  10. I didn't use any darks, just flats, as the lens produces a heavy vignette. For M31 I only had 36 useable (as I said the clouds rolled in) 90secs @ ISO1600, and I had 70-80 for the Rosette, same exposure settings as M31. Yeah this mirrorless Nikon Z50 is a gem. Just did a little more processing on M31, using StarNet to do some star reduction, it maybe too much for some, but I like it.
  11. No moon Friday, but not as many subs as I would have liked due to clouds rolling in. But I'm happy with this M31. This little Nikon Z50 and kit lens really is good. Last night was completely clear, so I thought I'd see what this un-modded camera could do with the Rosette, wow, not a bad 1st attempt.
  12. Didn't end up with as many subs as I would have liked due to my inexperience, but it turned out okay. Just goes to show, I doesn't matter how many YouTube videos you watch, actually going out there is much more valuable.
  13. Hi everyone. Looks like I will get some favourable weather in the coming days, but the moon is out and full. I finally have a car so I can get away from light polluted Weymouth, and tonight I took a drive and found a great spot to shoot (see image). So to the point, I want to shoot Andromeda during these moonlit nights since the moon will be directly behind me. How much will it still affect my images? I'm still a beginner, using a Nikon Z50 and the 50-250mm kit lens @250 (F6.3), but I do have a Star Adventurer now, so I'll go out and shoot if nothing for the practice (my polar alignme
  14. I finally got to use my Star Adventurer the other night, and I've had it since October! Stacked 26 shots at 30 seconds each at ISO800 with a Nikon Z50 and kit lens @ 250mm. Very please with my first outing with the Star Adventurer I prefer to not go to far over ISO800 as you start getting diminishing returns, you can look up a chart showing the ISO performance of your camera. Anyway, here is the final image, The Orion Nebula.
  15. Hi, Are the three screws for calibrating the polar scope done up (do not over tighten), and have you calibrated the polar scope?
