  1. I never thought about filter sizes, thanks for bringing that up. I also came across the QHY 163m variant. Does this have the same, larger backfocus requirement?
  2. Nice, that's quite a range of different cameras! I'll try find some reviews on the Altair versions. If not, I'll probably go for the ZWO considering its great reputation.
  3. Cheers Adam. I'm looking at the Altair astro 183m now. It's a little cheaper than the zwo and comes with a nice case. Seems all the same to me, are there any caveats you know of with the Altair counterparts?
  4. Okay, thank you. That's nice for just one hour!
  5. Hi, I'm considering taking my first step into the money pit of mono imaging, but I'm stuck between two options. The 183mm or the 1600mm. Currently I'm using a William Optics Z73. The 183mm is more appealing to me at the moment because of the price, I could buy it along with the filters and it would still cost less than the 1600mm alone. I like the FoV of the 183mm as well, as most objects fill the view with that sensor and my scope. But I heard somewhere that the 1600mm is more sensitive? Or Less noisy, can't remeber. Either way, is the 1600mm going to be that much better or not? Or is it just down to the size of the sensor? Also, what models are best for either of these cameras? Considering the ZWO, QHY and Altair options I wouldn't know what's better. Or is it just down to price and availability?
  6. Okay. Thanks for the input everyone! I'll try looking into the Omegon scope more, but I'm leaning towards WO. As @blinky said, at least I know what i'm getting.
  7. Hi everyone, I'm in the market for a new apochromatic refractor for widefield imaging. At the moment i'm set on the William Optics Z73, but then came across this: https://www.astroshop.eu/telescopes/omegon-apochromatic-refractor-pro-apo-ap-71-450-quadruplet-ota/p,60855. I've not heard of this brand before, does anyone here own this telescope or know about it? Price point looks great for what it is though. Any other recommendations for a widefield refractor to take into consideration? Cheers and clear skies, James.
  8. Yeah, I've done that already, looks like I'll need a few more mm off then, thanks for the heads up!
  9. Oh right, okay that makes sense. Thanks again for the help! Clear skies
  10. Update: If anyone was curious about what this could be, it was down the the belt. I had to take it off, flip it around and adjust the tension again and the clicking was gone. Glad the drop didn't cause any damage!
  11. Just gathered a few more test frames, that weird coloured blob seems to be moving across the frame?! Now another bright blob around Vega has just popped up! These are some nasty looking reflections, but I don't know what's causing them. L_0009_ISO400_120s__20C.CR2
  12. Luckily enough, tonight is a decent clear night so I've been able to do a test run. Stars are looking nice and round all the way to the corners now, so you were correct, thanks a lot alacant! Do you have any idea what that odd looking thing is under the bright star? I'm guessing some sort of reflection. Looks like I have a slightly twisted spider vane as well.
  13. Hi people, So I've been a bit of a fool and managed to drop my entire HEQ5 Pro mount head on my foot (Ouch). I was carrying it upstairs 'attached' to the tripod so I could make some adjustments to the DEC axis since there was a slight amount of play. So I set the tripod down and bam, the head rolled off and landed right on my foot. Silly me didn't realise the head screw wasn't done up all the way! So I gave it a test to make sure it was okay, got the hand controller out and moved it in both RA and DEC and it seemed fine. Then I decided to proceed with what I was going to do in the first place, adjust the worm gear engagement for DEC since there was a bit of play. After following astro baby's guide, I can hear this awful clicking sound when rotating the DEC axis a certain direction. I've attached a video below to show what I mean: HEQ5 Video.mp4 Any help on this would be greatly appreciated, I really hope I haven't messed it up too bad. Cheers, James.
  14. Yeah I know. But the clouds rolled in quickly so I only had time to quickly look at polaris out of focus. I did briefly view the star in focus but it still looked to have that fringing on the edge, but the clouds soon rolled over so I couldn't tell properly. I thought that the out of focus star test for collimation was supposed to look the same in the edges as it does the center ? It looks to me like the dark circle has shifted slightly when at the edge of the frame. And I've already cut off some of the focusser, looks like it may need a little more cut off as you suggested, though. Hopefully I'll get a longer patch of skies tonight so I can actually test the stars in focus. I just assumed that the out of focus star test looked bad at the edges - but we'll see. Thanks for helping out :).
  15. Well this is not the result I hoped for star test at the centre: And at the edge:
