If you like 2” eyepieces be aware that I could not reach focus with a 2” GSO Barlow and 2” 30mm APM Eyepiece! The focuser hit the stop ! Text SVBONY no response!

Thanks for these videos. I have several D50s on the shelf and I thought it would be fun to make a full spectrum camera. Do you have a naked sensor or were you able to find the right size glass to replace the filter?

Your Mouth Smacking while You were speaking is extremely agitating... couldn't watch to the end or even 3 minutes.

Quick question.... When using CPWI and PHD2 together, do you need to run the Celestron Alignment BEFORE connecting with PHD2? Or can you simply connect your scope to CPWI, then run PHD2 and let PHD2 do the calibration/alignment?

Thank you for showing us the steps, I just bought it and I need to find out everything. Thank you.

Is the lens cell made of metal or plastic ? I have a Svbony 102/714 mm ED refractor and it is excellent, with very nice image quality, with a lot less chromatic aberration than my Bresser 102/1000 f10 achromat.

I tested this scope for two weeks and had problems with focus and images were not as sharp even with image correction filter. Quality of the telescope was awesome. I have the Sv48p 90mm that is awesome and I use it for imaging rig.

I'm not expert in optics, but I think the old lens has astigmatism, stars looking like crosses. The replacement looks better, maybe once you tame the tracking issue and also if you add a generic field flattener, star shape will improve even more. In case you are interested, there is a god scope that normally doesn't cost too much in the used market and is really good, the Orion/celestron/Skywatcher ED80. Underrated scope, but is very good. But if you plan to keep the svbony, that's fine too, we gotta use what we have! All the best. Clear skies!

Thanks for the video. I wanted to buy a replacement to my Celestron AZ102 660mm which isn't perfect, but now I think the AZ102 is much better than even the revised version of 48p 102mm svbony. I'm glad I cancelled my order.

Pinched optic case...??? Or lens curvature defect...???

My experience with Stellarium is that Explore Scientific telescope mounts are not compatible with it. This may be old news. You wold think if you are using ASCOM the brand wouldn't matter. I have an Exos 2 GT with PMC Eight and when I try to select ASCOM from the download list it refuses to open it. It does accept all the others on the list. I'm using APT which works with Stellarium. You select a target in Stellarium and click the CTRL button on the laptop and the target on the screen at the same time and the mount slews to the target. Make sure you have Stellarium selected as the planetarium in settings. I hope this helps. Thanks for your video. I'd lost connection with the mount and couldn't figure how to reset it. I hadn't noticed the Profile Explorer Diagnostics link. thanks again.

thank you so much for taking the time to walk us through this. this is exactly what I needed!

Awesome video very well explained thank you

I’ve bought a eq5 mount, seems very complicated but I’m hoping to test it all out when I get some clear skies

A simple telescope, a star map and dark skies is very enjoyable.

Man I just ran into your channel. This particular video was super relevant to what i'm working on right now, albeit with a 6 inch mak. Prepping for jupiter, my first planetary attempt. I'm a fellow hoosier down in spencer, indiana. Hope you keep them coming.

Doesn't work all that well for astrophotography, if the deep space object cannot be seen in the finderscope or the telescope. You just have to take a 10 or 15 second exposure and if it show up, use a bright star to center it by moving the bright star and then take another exposure. And, if it does not show at all, move the scope a bit and retry. In my Bortle 6 sky, I spent a lot of time doing this, until I bought a GO TO mount.

I have the Helios 2x40 ones, I love them. Whilst I like my regular 7x50 binoculars for airplane spotting for me those are already too shaky. With the 2x ones I have zero shake and being able to see a whole constellation with dimmer stars added that I don’t see without these is what drew me to them. Im in a very “light polluted” area but ive also taken them to somewhere really dark and i was just blown away.

Hello are you still using that Orion atlas EQ mount. The school let me borrow theirs from their old storage room for the planetarium. I am hoping to use it as i only shoot on an Alt-Az mount

Theyr being pulled by a plane. So easy to see theyr not in space

I have a Celestron 102mm XLT on a CG-4 mount with an Astro-Gadget go to conversion kit. At 1000mm focal length, it comes to f/9.8 focal ratio. Sounds like yours. I polar align and capture with Sharp Cap Pro. I do not do guiding. Don't really need it. Usually run 4 second exposures unless I am using a dual band filter, where I use 15 second exposures. In the past, I have limited total exposure time to 15 to 20 minutes, but recently extended total exposure to 1 to 3 hours. I live stack with no post processing. I do post photos on my channel. You are welcome to come and visit.

This is a good eyepiece, it's actually about 58 degrees but still wider than a plossol. The other great thing is it's has good eye relief which makes it very comfortable to use. I have an ES 24/68 which is wider fov but not as comfortable to use as the 27 angel eyes ep.

Interesting.

Clever.

Thank you sir, you taught me quite a bit with this video.

WOW GREAT PIECE OF MACHINE !!!!

Inventive.

Cool! I remember playing with it too. The major issue was that these regular Ha filters work best at a f ratios greater than 4. I guess the applied chemical layer gets "too thick" at greater angles of the lightwave in faster lens. So, for example on Canon prime f1.4 lens with Optolong Ha filter I had nice results in the middle, but a huge vignetting at the edges.

Neat.

Hello and thank you for your video. I got a similar set-up than yours (SW 120/1000 + EQ5) and I mainly use it for solar observation (with a Herschell helioscope ! Never forget the filter or the helioscope for sun observation of course !!!). Your explanations were clear and I'd wish have seen your video after purchasing my telescope. PS. 375 dollars for this great set-up ? Here in Europe, telescopes are about 30-50% more expensive than in the USA :( Clear sky !!! :)

There Is No 70deg In A 27mm EP.. Thats Why This Is Hard To Find..I Finally Got Mine,It Was $61,Where I Paid $33 Each For The Others…They Work Fine For Me,And Now Considering A 2”..We’ll See…Just Wanted To Come Bck And Say I Finally Got Mine….Clear Skies…I Have A Heavy 32 Plossl That Came With My Celestron Mak90 And I Love It

Great video! I just received the IEXOS- 100 PMC-Eight 2 days ago and tried to connect with explorestars on my laptop. I followed all the instructions, but to no avail. So, I went out today and purchased a Samsung Galaxy A9+ tablet and I'm still not getting any communication between the tablet and the mount. I don't know what I'm missing. Any pointers will be greatly appreciated 🙏 Greetings from Ontario, Canada

I got the Orion 2x54. It does have a larger field of view than what you have. I know because I purchased yours at a much more premium cost. The Orion's are all metal. They do not bring in stars as dim as yours due to the magnification difference but that is what gives its wider field of view. I am in bortle 7.5 and I am able to use mine in conjunction of a red dot finder. I can see the stary background and the red dot at the same time and helps in guiding my scope manually.

Nice binoculars.

Great work Sir 👏

My experience with Explore Scientific (which is a lot of experience) their customer service is barely adequate. Glad you got helped. Seems when you are able to contact them they are fine but actually making contact as well as providing shipping information is where they drop the ball.

Great explanation, really appreciate it.

Just Ordered This One,But Received The Rest Of The Set Today..And Their 2X Barlow,I Like That Twist Up Cup,Maybe Be Able To Play With Them Some In The Morning Or Tomorrow Night,Good Review..Thank You

I bought one, and it has given me nothing but problems. It's junk far as I'm concerned.

Nice review thanks, could you tell how worse it is when the dew protection cap has got a little Crack does it affeckt the Scope? Cause i will buy my first Telescope and i could get exactly this Telescope but with a litte crack in the dew protection cap.

Interesting.

Neat. Wish I could have seen.

Excellent video my friend, you've done more in a few min than 20 other vids did in days. Thank You

Just bought the Celestron version of this scope.

Neat.

Clever. Just subscribed.

That telescope is the BRESSER First Light AR-102/1000

The longer the scope or the bigger the F number like your F10 , that is basically APO or at least FPL 51 glass , that is lower quality ED glass , so its kind of APO even tho it is not , it doesn't bend light so much hence the color focusing is good , if it was F4 with same glass , it would be totally different , so basically you got a very good scope , VERY GOOD SCOPE ! I wouldn't hesitate to get one , but locally there is not one there is F8 150mm ED , that will practically behave like that one just 50mm bigger aperture , same length i think , though it cost probably like 3 of those . There are all kinds of these Astro Reviewers , and you found a best scope . Congratulation , you will have a lot of fun with it . I just wish such scope was available locally where i am , but no .

Thank you Sir for being bold, making the conversion and sharing it. I've been thinking about doing something similar and your shared experience will embolden me to do something similar. What is your recommendation in terms of IR filters to put on lens itself for general non-astronomy picture taking. Thanks.
