I'm a visual observer and I wonder if you could share information on How to Get to the Observing Area shown in your video? Is that at some place on Seep Ridge Rd? Thank you and Clear Skies!

Is the edge really worth 1200 dollars more than the non edge?

I am having a similar issue. My next test is to se what I get without the field flattened. If the stars look all symmetric then I would guess it’s the flattener. If it’s to one side then it could be flexure or collimation. Have you rotated the camera to see which way the comma moves if at all?

Don’t know if that scope is worth all this. The flattener alone is probably 70% the cost of the scope. Better to just sell the scope and go with something better.

The four little grub screws are potentially lateral alignment adjustment, used at the factory to align the centers of corrector and secondary with the primary. My vintage Celestrons use cork shims. Lateral and rotational matching of the corrector is performed to get the wave error as low as possible and meet specifications.

The original axiom lx version had the same optics as explore scientific since joc made them for meade (series5000 uwa) and celestron (ax lx) before es existed. After several years of es being a budget option, joc decided to exclusively make es, raise prices to posture as a premium brand and celestron and meade had to go to different suppliers. The new meade 5.5uwa is absolutely excellent right on par with a nagler, but the larger luminos focal lengths do have issues. The meade 4 , 7 , 16 , 28mm ultrawides are the same as wo uwan and are really good I used to have the 23mm axiom lx and it was amazing. Es is a bit overpriced. I now have the orion versions of the 28uwa and 20xwa and they are better performers than the es82 30mm and es100 20mm

Whow, Eagle really came out great! I‘ve imaged it for the first time out of my backyard about two years ago. Of course with the 6SE on an Alt-Az mount barely able to take 15 second pictures and my daily dslr behind it there is no comparison. But still, when taking MANY of these 15 second pictures and do all the postprocessing-magic you can easily see those pillars of creation. And this always makes these crazy Hubble and JWST- mages so much more real to me. Nice video! Greetings from Switzerland where one rainstorm after the other makes my telescope getting covered with dust 😩😉

Nice video. My C11 has been a trial of patience but the reward has been worth it.

B2 skies would be awesome to have handy within a short drive

I use the "Explore Scientific Field Flattener f/5 to f/7" and I haven't had any issues with it.

Hello, greetings from Moab ! I see you have not uploaded in a few years. Are you still imaging out in the beautiful desert skies ? I'm just 7 miles outside Moab in Spanish Valley and if you ever want to spend some time here I have got the place. I'm on 5 acres and although in the valley we still have some stellar views. I have mesa views 15 min from the house as well... I'm using the Celestron 8 inch Edge as my mane scope, but have a travel scope setup as well. Anyway I thought I would say hello to a fellow Utahan. Cheers.

It was nice taking me back to that beautiful desert south of Vernal. I spent a few years in the patch south of Vernal in the mid 2000s. Loved that beautiful landscape!

Great video ty. Im wondering if it might be easier to dig up that desert and move it to your telescope?

Make sure you are not get abducted by aliens..They love places like this.

I just popped the secondary out and used kimtech wipes while wearing thin vinyl gloves to remove the haze that had collected inside the corrector plate. Other than the minimal amount of dust that snuck in, it's as good as new.

You should have moved to Arizona. Clear inky black stabie skies without interference of civilitation. Make sure you bring you 9mm pistol to secure yourself from Biden's invasion.

Great video! I have used both lines in my 12.5 f4.8 scope. The ES is the best bang for the buck, and the Luminos is not far behind, but they clearly shows aberrations. That said, people who say the “ring of fire” is awful are literal purists who want perfection to the edge of field. To my eye, the Luminos 10mm and 31mm are the best. And let’s be real: you are still getting 82° field of view. Most people like myself only care about the central field and don’t care about the extreme edge.

Do NOT wipe the corrector plate with anything... Use a Polymer Solution from Photonic Cleaning Technologies.

i need to learn how to do that , i have a billion questions?

Wow! Great video. Out there on your own all nigh, inspiring. 👍👍👍

Good 9:49am july22/23

EQ6 R Pro handles the weight sufficiently for long DSO exposures ???

Beautiful time lapse, tell us how you setup the camera and exposure.

I use 1 to 4 rolls of quarters to assist in balancing or biasing plus its backup emergency money.

Hi good work on this, any update? I just ordered this scope with the 0.8 RF/FF and plan to test the 0.6 RF/FF on it making it an F/3.6 fast scope at 254mm.

I too have the AT72EDII and the AT flattener/0.8 reducer. One thing I noticed watching your video, you are running the field flattener in to the 2” compression ring accessory holder (the black ring with the 3 thumb screws you mention). I removed the 2” compression ring accessory holder and screwed the flattener straight in to the rotator (red ridged ring) My back focus is working well at 55mm. I wonder if that would change the back spacing needed for you, as the flattener is picking up the image cone in a different place?

I'm 76 and have been an amateur astronomer since 1969 when I bought my first telescope. It was one of those 90mm "department store" refractors, but when I took it to the beach I fell in love with astronomy. The darkest sky I've seen was at a star party hosted by the Las Vegas Astronomy Club. We drove 150 miles to the northeast of Vegas and viewing with a bortle 2 sky was mind-boggling. The original owner of the 36" dobsonian "Yard Scope" was there and after I got nosebleed from climbing the absurdly high ladder, I saw the Horsehead Nebula in all its splendor. I am too old now to handle a decent size scope so I scan the sky with 70mm binoculars on an Orion Paragon mount. I applaud your choice of scopes and wish I still had the strength to handle one. Cheers!

Is there a field flattener for this scope that does not reduce focal length? Maybe the Orion 1?

I too have the 73a flattener with the AT72EDii using a Nikon t-ring and setting the flattener at 11.4mm per WO’s instructions I get a nice flat field out to the edges on my Nikon D810a. Now my Real question could you use this flattener on a 102??

your camera will cut 17.5mm from that 57mm range.

Well done. My first attempt at this last week caused a crack in my C9.25 XLT corrector plate. Hopefully help is at hand.

Great video. I thought I would chime in with my recent experience. I have a William Optics Z73 with a William Optics Flat 73r flattener/0.8 reducer and struggled like you have. A friend suggested N.I.N.A. Hocus Focus Aberration Inspector. Great tool. It tells you if you need to increase or decrease your back focus and measures tilt. I dialed in my flattener in one evening. I ended have to adjust my flattener 1.7mm beyond the initial recommended. The initial recommended is for Crop Sensors and mine is a 4/3. I have no idea why that would make a difference. I ordered some Astrodymium tilt rings and adjusted my tilt. Problems solved quick and efficient.

Cat love moon!!!

Nice video, great drone shots! :)

Appreciate your honesty.

What hand motion did use to actually clean the glass with the wipes

Just curious, why use a filter if you are under a Bortle 1-2 sky?

It may also be a focuser problem, I have the same issue with WO GT71 with 6AIII FF/CORRECTOR, or with Hotech SCA FF… I will check with a friend for the focuser alignment, according to him it must be the cause…

What's the verdict on these?

Thanks for this video!

Looking at your setup, you need to add 55mm from the back of the Flat 73A to the sensor. I don't thing you are even close. I installed the 73A on my GT71 and it work just fine with both my ASI183 and ASI071.

Hi. I'm new to this so liable to say something stupid but I found myself wondering if the results would be similar with a different imaging camera such as the ZWO ASI533MC Pro?

Have the same issue with my AT80EDT and their field flattener. One solution I came across was to use a 'tilt corrector'. Way too much $$ snd more weight on the mount. In the end, my opinion is that it's a flaw in the flattener that the manufacturer should fix.

How much (ASTRO-TECH AT72EDII) back focus? Thank you!

Beautiful sight seeing the Milky Way 🔭

Hello, what are your thoughts about using the EQ6R mount versus a Celestron brand mount (for instance the CGEMII) with the EdgeHD 9.25? I've heard good things about the EQ6R but since I'm a total noobie I'm wondering if I should stick with a Celestron mount to make it more turn key.

Do you have any problems to turn that plastic cover of collimation screws with fastar stick? my turns about a milimiter and stucks. Any suggestions how I can get to this collimation screws?

Hey guy, I have a C11 EdgeHD and I love the Luminos Line of eye pieces. Collect them all!

It looks very much like a clone of the Atair astro 72EDF as my other half has one & she uses the Altair lightwave 1.0 flattener with hers so I'm guessing the same would work with the astro tech.
