William Optics REDCAT 71 (first light!) 

Thank you for the shoutout Trevor! We are indeed already working on a solution with our Deep Sky Dad AF3s motor or ZWO EAF motor. We will also prepare an automated flats panel with integrated heater, field rotator and more! First light looks great, can't wait to see more images with this OTA! Our unit is still in delivery, but we have bad forecast for the week anyway.

Thank you for this video, Trevor. I received my RedCat 71 today, so Germany will have a couple of cloudy nights now ;)

I always love that you show your in-progress images - things don't have to be perfect or completed to share, and I appreciate that about your vids. Cheers buddy.

Fantastic! So excited that William let you test out the CAT 71 before it is out yet for sale. Great job!

My favorite kind of video. Really enjoyed watching. Beautiful picture.

That looks fantastic! Thank's for the review. Well done Trevor 👍

It’s as if you have touched the heavens for us. You’re an amazing young Man and an inspiration to us all. Thank you

when I was first starting out, looking for my first upgrade from a kit lens, discovered this channel and your redcat review at the same time. Ended up getting the Spacecat version and is still my favorite scope out of the 3 I have and 3 rokinon lenses.

Thanks for being the guy out there doing it. It gives people like the myself the motivation and inspiration to pursue the hobby.

Looks like a killer imaging scope! when I grow the nads for imaging I will definitely remember this gem!

Damn, the observatory is looking sweet Trevor, looking forward to seeing some great images out of there.

Nice work Trevor! Awesome scope and image! Keep it up brother!

I was wondering when this scope was going to appear - looking forward to seeing more images from it. I love my Redcat51 so I'm sure the 71 will be just as popular.

Fantastic first light and I look forward to seeing more of the that redcat 71!

Great video as always, Trevor! You inspired me to get to nebula photography, starting my journey with RedCat 51 and 8” EdgeHD🙂

Looks like a great scope, the WO gear is always well received. Great vid as always.

Great piece Trevor. The scope is a beauty and I loved the image. Really good technical info you provided also, and the image was like something from a futuristic sci-fi movie. Superb 👍☘️

Another great video! I bought my RedCat51 after watching your review, and it is one of my favorite scopes to use, day or night. If I didn't already own the Orion ED80T CF, then the RedCat71 would definitely be on my must have list. Looking forward to more amazing pictures that help inspire me! If only I had clear skies more than once every other month. Also, hello from Alberta!

Very nice! Can't wait to see it!

Nice First Light of this scope everyone has been waiting for. Curious to see if WO goes up a level to bring us a similar design closer to the 90-100mm FL. Love these scopes. Thx Trevor for keeping us up to date!

i just feel so good watching your videos

Thank you, Trevor 🙏🏼 My first light tonight with my new Redcat 51. Hoping clear skies remain until tonight. Greetings from Indonesia!

Beautiful cable management.

Nicely done Trev.. That's a tasty bit of kit.

"Im Seeing Red" 🤯Great Review Trevor!! Very cool Looking Scope!! Love The Combination with that Zwo Camera, Full Red,and Even The Nebula Is Red. Great Shot man!!👏🏻

That is definitely a great shot!

You're already producing fantastic images and I can't help but wonder what you could do under a clearer sky! Also, thanks for piquing my astronomical interests. I've gone out and picked up a nice used 10" SCT and started enjoying working with it.

I can’t wait to get my hands on one of these. I have the SpaceCat and really like it.

I just bought my first telescope because of you trevor!! Now hoping for clear skies.

Amazing one!

I have a GT 81 and SpaceCat 51, so I probably won't get a 71 for a while, but I love that William designed in the focus gear ring. Awesome video!

hace 6 meses empecé a practicar la astrofotografia, y justo encontré tu canal, que envidia ese cielo que tienes en tu casa. te sigo en YT e Instagram, agradezco tus videos, de verdad me inspiran. saludos desde Chile!

I like the gear ring for the autofocuser. It's a nice addition to have. There were some complaints about using the DSD on the 51's user group. Apparently, it put too much pressure on the helical focuser of the 51. I currently use the black cat mount with my 51, and it's been doing well.

So cool man. I've never imaged that one before.

The montage's in this video man that is awesome

Great video on the new Redcat. I have the first version of the 51 but I will get the new collar to put a new top plate for a guider and the larger bottom plate to be able to balance it better. What a great scope. The 71 is cool also.

Hey Trevor, Every time I watch your videos I’m so inspired by your amazing enthusiasm & love for what you do. I’m early in the journey of astrophotography here in the UK shooting with a Canon R6 & ef lenses on an iOptron Skyguider Pro with a little autoguiding help from PHD 2. I’m waiting for my ASI Air plus to be delivered so I can operate my rig remotely but sometimes find myself frustrated by the amount of time it takes me to find & frame some of the smaller dso without a goto mount. Whenever this happens I watch your latest videos & I’m immediately reinvigorated to get out there and try again. Keep up the good work.😀

I literally heard about the RedCat71 yesterday and hey presto there's a video today!

Thanks for all the great vids! You sir made me wanting to join the hobby, even though it’s not so easy to have the necessary equipments down here in Brazil ;-)

Nice work Trevor. I love my WO GT81. Extremely good optics. I think Nico still has a few tricks up his sleeve for capturing asyro images. Great to have both sharing your information for us astro newbies. You got me into this expensive hobby, but I'm not complaining. Outside at 3:30 AM on a clear night is an experience that is hard to beat. Your subtle comment about a winter scope has me thinking that you could help us beginners with some tips on how to deal with winter weather and our astro gear. Do you leave all of your gear in an unheated enclosure during the winter, so that it does not need to climatic before imaging? Do you have a low temperature cut-off where you may consider equipment damage (mount drives for example)? I live in Ottawa, so we get as cold or colder than you in Southern Ontario. Cheers, enjoy the dark fall skies.

Fantastic work and the Redcat looks the business Trevor! The Observatory looks awesome! Please do a video specific to the observatory/set up please my friend! Thanks! Wes, Liverpool UK

Trev, proper astronomer, props dude.

Beautiful image

The end result is - - - 'Awesome'..!!

Loving the backyard and clear skies, too many neighbours floodlights here. . .

Awesome video! I shot the Orion Nebula for my first time last night, I can’t wait to try again!

Well done Trevor! One thing about the red cat: it looks sexy as heck!

Not sure if anyone mentioned this, but a quick fix for your cable management is go to the local hardware store and buy whatever length and diameter plastic tubing that will hold your cables and then just cut down one side of it. Boom. Done. Or get some zip ties.

Great content ❤️

I am surprised to hear that there are still objects you haven’t shot yet 🙂 Great scope. Cannot wait to see the price tag and more details. Cheers from cloudy Vancouver.

Great looking new Redcat!!! With the way things are, we may not see this scope out and on sale until later this year or early next year.

Beautiful image Trevor. I wonder if we both shot this for the first time on the same night haha. The Squid is FAINTLY there. Enjoyed this video, as always.

Wonderful scope!! - I can't wait to see more from it over the coming sessions, I'm sure it'll impress just as much as the RC51 does :-) Have to agree about the squid by the way, definitely not a 2hr target haha :D Clear skies man!

Looks like an amazing scope! I hope they make some longer focal length quadruplet scopes.

Thanks for the demo Trevor. I have been looking for a smaller refractor for a more portable wide field astrophotography rig to complement my Tele Vue NP127is-AP900GOTO rig. Will keep my eye on the Redcat 71.

Cool Man!

Wow. Great video. I wonder how on three hours of sleep you can still generate so much enthusiasm.

Cheers for this trev been waiting a while for this

Own a FLT132 and ZS81, both of which are red. WO designs and manufactures top-notch stuff.

Looks great to me for one night on new gear. 👍🏼

Nice!

Thank you for the review, I enjoy your videos. I know the mount was not being reviewed, but which model is the one you used for this video?

Wow!

Excellent video! The cat 71 seems to use a very similar lens design as their older Star 71-ii scope which I have and it works a treat

Hey Trevor! Love this video. I have a question about focus on a REDCAT 51 I have. First question , should the tilt adapter be removed prior to attaching a camera? Are there any back focus requirements? I cannot seem to get clear focus on anything. And the manual does not mention any of this. Thx Much Mike

Love to know more about what tone mapping is and how to do it.

Lovely looking piece of gear Trevor, heard so many good things of the Redcat 51. I do wonder why they don't make a slightly better Bahtinov Mask on these though for a sharper spike. Cheers Ollie.

Incredible image and video Trevor! Have you ever tried to image the Deer Lick group and Stephan's Quintet? I saw a picture of them the other day and I thought that with your gear and expertise you could probably take a really special picture of it.

Interesting, basically similar to the old WO Star 71 flatfield scope in redcat setup, 71 mm, f4.9. There are quite a few scopes is identical to this, such as TSAPO71Q which I have, and this 350 mm scope is a great widefield range.

Thank you Trevor. May I ask what post processing software you used here?

I'm very new to all this and feeling my way on all the auxiliary equipment that goes into this. Could you list all the attachments in use, as it would really help me learn?

Nice bro

I know that a Petzval lens is an old-style photographic lens that, because the right kinds of glass weren't available, used the dodge of correcting for curvature of field by means of astigmatism - so that it had a flat field for at least one set of rays. Astronomical telescopes, of course, usually have objectives that are just a single achromatic or three-element APO lens, they're not complicated like a double-Gauss photographic lens. So maybe Petzval is a step up, but because modern glasses are available now, I can see why people would have doubts about that design, even if they're not justified, and this is an incredibly good telescope.

Thanks for this video, one of man great ones, Trevor. After lots of research, I've settled on getting a Redcat 71 for my first refractor. Quick question. Does one need spacers for the right backfocus with the 71? I'm planning on using a ZWO ASI294mm and a 20mm filter wheel on mine, so am wondering if I might need any spacers. Would be most grateful for any feedback. Thanks again for the great videos!

I had to rewind to watch that slow zoom shot of you turning the lens’s 🥶🥶

техника шикарная и фотографии очень красивые!! молодец

Regarding the observatory. Was wood planks the best option? doesn't it create movement on the telescope when you step on the floor?

That looks awesome. Just purchased Esprit 100. Now I have to look for the Rescat 71. I am broke😂😂😂

Hi Trevor, I've sent you a set of cable managers a few weeks ago, hopefully, you'll have a chance to check them soon. They fit extremely well on ASIAIR and the ZWO cameras and allow for great flexibility in your setups. Cheers, Nikolay

oneday i m gonna buy it

Nice bit of kit ( pun intended) you have there. Superb videography. How many scopes do you have? I thought the flt132 might end up in the observatory

video very interesting

nice

Trevor. How did you mount the ASI Air in this video? I was hoping to do the same but upfront away from my EAF.

Great video, I have the RC51 and GT81, I think another scope in a similar range won’t pass the wife test…. Hahah.

Looks nice. Would like to see a comparison of both red cats shooting the same target at the same time to tell if the 71 is actually better than the 51

This new scope looks great! Did they give you an idea on the expected price? What’s the weight like? Is it to much for a skyguider pro?

The piece of equipment I don't see listed is that red headlamp. What is that please?

Hey Trevor, I'm about to dive in and purchase a telescope. What would you recommened between the Meade 70mm Quadruplet and the W O Redcat 71, please?

Great video. Which filter drawer is that? My RedCat 71 is going to be delivered on Monday (12/06/2021) and I need to get one. Can someone tell me, please?

I like the L-eNhance better than the L-eXtreme. I had some very significant blooming around bright stars with the L-eXtreme.

What camera mount would you use for a Nikon Z camera on this telescope?

your initial review of the redcat51 made me get that ….. & love it! now decided to get this .. something a little bigger

Can you use the red cat on a skywatcher EQM-35 pro mount?

Will this work on the Adventurer Sky Tracker 2i Pro?

Woah man, a pang of jealousy seeing that scope!! I wish these scopes were more affordable And more than that, *_in stock_*

That squid is such a pain... but I'm using an OSC too (533/L-eXtreme). Same results as yours, tbh it still looks pretty badass without the squid 🤘

redcat 71 vs sky watcher esprit 100ed super apo triplet - which is best both same price

hi pete, can you assist me in an issue. i just bought a am5 mount, coming monday but here is the nose rub. i need to buy a scope and camera but high point is telling me that any scope with the focuser towards the middle to front will interfere with mount, now that sucks. so i wanted a william cat but those models of course have the focuser in the middle. what can i do?

Can this be mounted to a skywatcher star adventure 2i WiFi pro?
