¡EXCELENTE!...😊
I love an Askar ❤❤
I‘m not 😂
@@exif6839 I guess it's personal preference. 🤷🏼♂️
@@jojogivens7475 this was a joke. But I love my TeleVue NP101.
@@exif6839 it's taken that way 😂😂🤣
Can a dslr be used with this scope ?
La modelo viene incluida con el ota?? 🫢🫢🫢
Just ordered it. Let see how it performs
This is potentially my first dedicated astrophotography telescope
I this reducer still capable to shot with full frame without vignetting?
It's beautiful I want one of these pentzval
WO Red Cat 51 II VS Askar SQA55 🤔🤔🤔
When is it available for purchase?
how much tension to put on belt? should it be very tight?
thanks!!
Using the music instead of giving more information verbally is a wasted opportunity.
Really misleading video.. 0:22 The back focus is wrong, it is way too large (71.5mm) it needs to be 55mm ... if you mount the camera like this. he is seriously out of balance. he leans back on the camera with full weight..when putting a vixen rail on it.. you cant rotate camera cause of focuser ...i dont know who build this but he or she dont know Sh,t about camera gear .. jeeeez
I ordered one as soon as it was announced. This is precisely the type of telescope I was waiting for both in terms of performance and price. My sample should arrive some time next week, I cannot wait! I also heard rumors that there is an 85mm version of this telescope coming out as well. I am also looking forward to that one! If the price and optical performance are good, I am definitely buying it as well.
Please don't use AI voices it really is not the future right now, it mispronounces words and is very unemotional and robotic.
Thanks for your advice😄.
Chromatic aberration? LOCA?
Focal length? Max aperture? Cost? Field curvature? MTF graph?
Hello😄, how about checking out our website for more product information? www.sharpstar-optics.com/Products_1/SQA55.html
How much equipment weight can the SQA55 focuser support? Would an ASI2600MM + filter wheel + Falcon rotator work without possible focuser play?
Its a helical focuser - the mechanics are internal. It doesn't use a focuser draw tube like most telescopes where it moves in/out from the back; no amount of weight added to the telescope is going to shift the focuser.
Please do not use AI voices it's distracting
What is the coupler hole size for the focuser shaft. Is it 5mm diameter?
Hello, it is 6mm diameter. You could also find this info(Product Size Diagram) on our website page: www.sharpstar-optics.com/Products_1/79.html#saf-detail-1
It leaves but one question. When will we see an Askar EAF?
Hello, we don't have a plan for this at the moment, but we will feed your suggestion back to our technical department.😄
Very beautiful refractors
How would this compare with the redcat? Would love to see real world comparisons.
Looks bad look like they spray painted it.
What is attached just before the camera? A filter drawer??
Yes, an Askar filter drawer😄
Really cool innovation. Out of the box thinking. I love it.
What is even that thing?
Hello☺, SQA55 is a quintuplet air-spaced SDglass Petzval astrograph, which can be used for astrophotography and daily photography~
What an interesting concept: a telescope with a variable aperture? Use it as a telescope by night and a photography lens by day. The optics for both are a bit different (flat field needed for astro vs. more forgiving at the edges for daytime photography) and what about chromatic aberrations and vignetting - imaging looks really nice, I must say. Looking forward to seeing someone test this in the field. Really applaud Sharpstar for thinking out of the box.
Nice scope
👌
When do you get to review it Trevor?
I think I'm in love.
Too bad it is still a ZWO, but time will tell what Sharpstar has to offer in a few months.
How long is the length when in focus with a zwo camera attached?
Hello! This length is also related to the length of the connected device, we recommend that you could find a near-ground target and turn on preview mode to focus.😄
I have just received Askar D1 and D2 Filters. Motivated by your video. However, I am trying to follow the steps in your video, but your mouse moves so rapidly, that at times playback multiple time to figure out what you clocked on where. With you would have kept the mouse on what you clicking on. At around 8:58 you say "save the images just in case", but I can't figure out how did you say the 3 images, I could see your move move all over the screen ? Exactly what are you clicking on to save all 3 images ? At 9:17 you select ArcsinhStretch, after this I just could not follow what you doing as the mouse is going allover so rapidly, cannot make out what is being selected. Tried replaying 9:17 onwards repeatedly but now able to grab what is being done. At 14:29 are you clicking on the Execute Square at the bottom of LRGBCombination and then also on apply Globally, arrow went to both so cannot make our what was clicked on, both or only Globally.
Hello, would you mind contacting us by email?😄 support@sharpstar-optics.com
This video is out of date. The riser is no longer plastic but machined aluminum and is secured by 3 machine bolts. It is solid with no flexure. I'm very happy with mine.
This is really good video. I just struggled with Askar 120 APO but thanks to the back focus adjuster my issues were solved. Thank you for making good products and looking after the customers.
Is the EAF bracket the one that comes with the EAF or is it a separate purchase item?
Hello, the EAF bracket is the one that comes with the EAF😄
Already ordered can't wait for testing this new product amazing stuff from Askar
Hope you will enjoy our product😉
How much is it? Take my money!
Hello, the price is $1,695.😉 You could contact your local dealer for more delivery info. sharpstar-optics.com/Contact_1.html
I bet they use words like "affordable" and "Resonable" when they properly advertize it! 🤣
👍👍👍
Hello!
Very nice! Thinking of getting it
I would feel better about your scopes if you say what glass you are using and provide more detailed information on the tested optical quality. I have seen posts that some scopes have been returned due to optical issues too. I am concerned about quality control.
Hello😊, 140APO and 185APO are both triplet air-spaced APO lens design, including one piece of ED glass. We do not differentiate between specific models and refer to them collectively as ED glass.
The M48 thread can be replaced with M54 thread instead, for ASI2600MC Duo?
Hello☺, you'll need to get a M48x0.71 to M54x0.75 adapter depending on your backfocus.
Hi Team, I photographed the Crab Nebula with your amazing C1 filter, here is the video and I think you can promote your product with this video because the result is awesome th-cam.com/video/Zr_r4GQ3QMw/w-d-xo.html
In my case, both focuser and tube seem to be stuck, can't unscrew them. Any advice?
