    I bought the Starizona reducer for my SCT a couple years ago. I sold the celestron reducer quickly afterwards as it was going to accumulate dust. Starizona have great reducers!! I also bought those for my refractors. Never looked back!!

      Yes indeed I must say the more I use it the more I'm liking it you can really tell it's a big step up in many ways from the Celestron one. 👍

    Thanks for sharing your results with this reducer. Stars look definitely better than with the celestron FR. And very nice interacting galaxies that you captured. Let's hope and wish for clear skies (although this start of summer in Australia doesn't look too promising tbh...). All the best!

      No worries and yes Indeed they sure are looking better. I'd like to maybe try this Galaxy without the reducer one day and get in closer. I know the weather of late is just dreadful I hope we all get a break soon. Cheers and clear skies to you soon 🤞:)

    I just put the Starziona Large format corrector / reducer on my C11. IT oozes quality, allows a lot more light to come through for my OAG-L and seems to correct the field very well. Images look excellent. Feels like I upgraded my cheap second hand C11 XLT (bought for about $1100) to an EdgeHD for less than half the price.

    • @OlliesSpace

      Hey Thanks Bill - I've always found this curious too as I've read they haven't changed this reducer since we were all using film cameras? Seems they are missing a real opportunity here. Yes the reducer is looking much better the overall image sharpness seems a lot better to me too, I always found the Celestron ones a bit soft, although that could be my imagination.

      Hey Jason Im pretty sure it's a keeper like you say, I've already ordered that Baader clicklock fitting so hopefully helps keeping all centered or at least will make me feel better with my whole image train feeling secure. Always a little unnerving with just a compression fit. 😬

    That looks like one heck of a nice reducer/corrector to me!! I'm not the biggest fan of the celestron/meade "classic" 0.63x offerings as the image seems soft and they tend to introduce some chromatic aberration too, hamstringing otherwise very capable scopes I reckon! - I think the clicklock sounds like a great idea too, I didn't know what all the fuss was about 'till I got one myself :-D

      Hey Luke - I think that's a good way of describing the performance, like you say the images always come out a bit soft and you can see that nasty fringing on the stars. I wonder if they just didn't bother developing a new one rather pushing the Edge series more. Shame like you say because the scope is very capable. I actually got the Click lock today! It does look very solid. Now I need to watch your video pal, it's on my list I need to find out why your hair got blown off 🤣🧑‍🦲

    I've got a similar experience as you with the Starizona reducer. It's definitively a step up from the Celestron one. The only thing I don't like is that I get some flare on bright stars probably due to pinching effect from the compression ring.

    Hi Ollie, I don't like the SCT to 2" adapter. So the Starizona SCT Corrector has M48mm female threads and I plan on using a SCT to M48 adapter and I think this will be more secure as it all will now thread on as the SCT to 2" can be a bit loose...

    I purchased the Starizona corrector for my C8 and was finally able to use it last night. I'm a little confused by your back space calculations. I have the Celestron OAG and have my Starizona attached to the OAG M42 female adapter (4.5mm) then the OAG body (29mm) then the OAG M42 male adapter (12.5 mm). I have a ZWO filter drawer (21mm) with an Antlia Quad Band filter, Then I have a 6mm spacer and finally the ASI071 MC Pro with 17.5mm. The total backspacing is 90.5mm which is on .2 mm longer than the Starizona 90.3mm backspace requirement. What was your reason to add an additional 5mm on back spacing?
    I have my OAG prism as far down as possible and I don't get any shadow on my ASI071 APS-C sensor. I also didn't have any issue obtaining guide stars with the ASI174MM guide camera on my target last night, M51, despite noticing the M42 OAG adapter seems to cut off part of the OAG camera hole when looking down from the OAG camera position. I have the guide camera sensor long side set parallel to the main camera long side so maybe only a small portion of the guide sensor is obstructed along the top.
    I find the Celestron OAG helical focuser a little too sloppy. I wish the camera slot had acloser tolerance to the camera cylinder. The two locking screws seem to tilt the camera cylinder so it rubs against the OAG focuser cylinder and you feel resistance in when turning the focus ring. I decided to try a 1.25" parfocal ring on the guide camera cylinder so I could remove the camera and not loose focus. It also helps center the camera and when the locking screws are tightened the tilt is minimized.
    I use the Baader Click Lock. Thanks for posting this video.

    • @OlliesSpace
      @OlliesSpace  8 місяців тому

      Thanks I think I may have got my spacing slightly wrong here and so long as you've got to your distance I'm sure you're good. Yes the helical focusser can be a little sloppy like you say. Hope you get some awesome images with the scope now, it's been a great piece of kit for me.

    I purchased the Starizona SCT reducer for my C9.25; however mine is a Mark III, so it really reduces the C9 to f/6.3 (f/6.26 with my optical train), but my sample at least doesn't do a great job with broadband B filter: stars are a bit under-corrected at extreme corners of my ASI 1600 sensor (which is even smaller than that of the 2600). Apart from that it is a great piece of glass, capable of transforming a standard C9.25 in something even better than a C9.25 Edge HD, in my opinion, as resolution is increased also on axis. Stars in your frame look pretty good and keep in mind a thing: I bet you will notice no improvement using a Baader Clicklock. I use it on my OTA, and I think the remaining distorsion you are experiencing is not related to the clamping method. Your stars couldn't get any better than that, I think. It would be great if you could check your B channel and report me back whether it is corrected or not. In case I could consider buying a Mark IV ;) Greetings from Italy!

    Great video! I have a question regarding back focus. Looking at the Celestron OAG documentation, I see that the female M42 adapter uses 4.5mm of back focus, while the male M42 adapter uses 12.5mm of back focus. The OAG body is 29mm thick. Then there is the filter wheel (20mm) and the camera sensor offset (17.5mm). So, if I do the math, I get 4.5 + 29 + 12.5 + 20 + 17.5 = 83.5, which is roughly 7mm short of the Starizona SCT reducer ideal back focus (90.3mm), so something is not adding up. Did you add an extension that was not mentioned in this video? I am thinking of getting similar equipment, so a clarification would be very helpful. Thanks a ton! And keep the videos coming, they're great!

    • @OlliesSpace
      @OlliesSpace  Рік тому +1

      Apologies I never got to this comment. Just checked and my setup from reducer is 11mm spacer > 4.5mm OAG connector > 29mm OAG > 12.5mm OAG connector > 6mm spacer > EFW 20mm > Camera 7.5 mm (no tilt plate so connected direct to EFW). Hope this helps. I use this specific configuration as when I connect my camera to my refractor I just need to add a 16.5mm to my 6mm spacer to get correct backfocus. Hope this helps.

    I don't know about this Starizona reducer, but the Celestron F6.3 reducer is sharper in the center than my Celestron 8 EDGE HD with the F7 reducer. Probably because it's f7 instead of F6.3. Now the new Starizona reducer makes the Celestron SCT 8 inch F7.1 again, so center sharpness can also change. I don't know what your experience with this is?

  • @KJRitch
    @KJRitch 10 місяців тому

    Are you able to drop the Celestron OAG prism low enough to get enough FOV to the guide camera sensor? I measured the width of my Celestron OAG body at 73mm. Half is 36.5mm to get the center point. I've calculated the closest the bottom of the prism from the center of the OAG body is 10.5mm. The size of the prism glass is 12.5mm x 12.5mm. The M42 OAG adapter is about 37mm diameter and 18.5mm radius. The prism height and the distance from the center will be 12.5mm +10.5 = 23mm). But part of the M42 circle will obscure the top of the prism by 4.5mm. I read the diameter of the Starizona SCT corrector is only 27mm diameter. Does that mean the prism will only pick up about 3mm of the edge of the corrector even with the OAG prism at its lowest level? The Celestron 6.3 correct lens diameter has a much larger diameter of 40mm. I have an ASI071MC Pro which has a similar sized sensor to your 2600. Have you set your prism at the lowest setting? Maybe not a problem since seeing your results. Just wondering about this since I'm interested in one of these correctors. Thanks.

      @@OlliesSpace On my Celestron OAG with the prism set to the lowest setting its about 47mm from the bottom of the OAG housing. It appears to clear my 23.6 x 15.6 sensor but when I take a flat I get a shadow at the bottom of my flat. I raised the prism and the shadow went away but when I put my M42 OAG female on the bottom of the prism is barely visible. At the lowest setting of the prism the M42 OAG female covers 1/2 of the prism but it would leave a shadow on the flats and I presume on the light frames. Are you getting prism shadow on your flats?

Even if the focus part is turned all the way to the left, it is slightly out of focus. The focus knob rotates 32 turns from far to near. Please let me know where your set is in focus.
    By the way, Celestron's original 0.63 reducer can be reduced with a back focus of 105mm.
