Well, the eclipse seemed to be a perfect time to bring out the OneSky. Also hooked up my camera as I have in the past.

At least for me your images are showing up broken, or the internet ate them going from the CN servers to my browser.

They got lost in the trip to your house. They are coming through fine for me in two different places.

Very nice moon images.  

 

Mike was asking recently about a upgrade/extras package for the OneSky. Many fine suggestions have been given so far.

Another thought, as so many of us with the OneSky enjoy capturing images of what we are seeing, how about a cellphone adapter for afocal image capture.  These appear to be relatively inexpensive,<$20 retail, and many if not most people have access to a cellphone camera.

 

Having an image to share with family and friends, when not directly observing from scope, is great outreach for the astronomy passion.

That's a great idea! I'll add it to the list of items. We haven't had a chance to do something with all the great suggestions so far but we will.

I've been thinking about getting one myself. Do they work well with the helical focuser?

so I was looking at adding a GLP to the OneSky.. I had in my notes that the dovetail groove mount was 11mm and that seems to match with the measurement I'm taking. don't have any experience with gun mounts, etc.. but it appears a dovetail to picatinny/weaver rail adapter is what I'd be after to mount my GLP.. seems like a worth $25 upgrade if I can get it to work. will post pics/parts if successful.

was just thinking of doing this as well.. it would be great if I could 'share' the image with a bunch of interested kids/scouts all at once :)

I just purchased my OneSky and I am delighted by the past postings of AP, that the ZWO cameras will do nicely with this scope. I have the ZWO ASI385MC right now (sold my ASI224MC), and I am ordering either the ASI1600MC or ASI294MC for wide-field EAA and imaging. I have been doing EAA with my Celestron Nexstar 8" SCT over the last few years, as well as planetary imaging, but I like the price and compactness of this telescope. Also, one Pro on this telescope is that you can slide the telescope tube down to achieve focus if you cant already achieve focus with the camera attached to the focuser at its greatest length.

 

I sent a request for samples to Formex for some 12"x24" Formex in .030 and .040 thicknesses. I plan on mounting my Onesky to my Ioptron ZEQ25 mount to use for unguided EAA and planetary imaging, but mostly for wide-field EAA/imaging. I will make my Light shield out of the Formex or Kydex from Scopestuff. I will also attach a Rigel Quik Finder or Telrad to the tube as my zero power finder. With goto, I usually do not need a powered finder because my accuracy is very good once aligned.

 

Keep the suggestions coming for modifications!

Has anyone attempted to upgrade the focuser to a rack and pinion type, such as https://www.amazon.c...e/dp/B0000XMXF2

Just curious what would be involved and whether or not it would be worth the effort and cost. Thanks!

It could probably be done, but it would require mutilating the molded plastic that the focuser screws into and would probably be pretty ugly when it was finished.

I LIKE the focuser.,I had never used one before and I like the feel of turning the "ep" to get to focus.,I wish all diagonals had a helical focuser on them.,I bought the William Optics correct image diagonal w/ helical focuser and it's really nice for fine focusing when you just have a R+P focuser.,

I may have a way around that, I've ordered the focuser, I guess I will see how good my DIY skills are, lol.

I don't mind it when directly viewing. But it sucks when I hook up the camera to it. Very hard to focus.

You can always move the truss tube down a bit to get the focus better, meaning move the diagonal/focuser upper ring closer to the main mirror, loosening the clamp down knobs and sliding the tube backwards, giving you more in-focus. That is one great Pro of this telescope. The same thing applies to the Skywatcher brand of truss tube telescopes.

This is what I have so far. Modeled the end cap in Fusion 360. Printed the parts in PETG.

Endcap and a spacer for the focuser assembly. The spacer also helps to hold the bolt for the secondary mirror.

Checking the secondary alignment on the original endcap.

And checking the secondary alignment on my endcap.

The actual focuser should be here tomorrow, I'll figure out how to mount it after I get the dimensions and weight. Wish me luck...

My OneSky is on its way, should arrive on Thursday, 2/8. I already have some good EP's, but I mostly do EAA and imaging with my scopes. I have the Neximage 5, ASI385MC, getting the 1600MC soon and the ASI290MM soon. I will make the mod for the light shroud and even extend it beyond the OTA a few inches for better darkening results. This part of the light shroud will be removable with velcro.

 

I have my Nexstar SE mount for quick goto sessions and a robust Ioptron ZEQ25 mount for EQ unguided and possibly guided imaging (Never tried guiding before). I have plenty of narrowband filters for Deep Sky and planetary lucky imaging like Methane, IR 642 and UVenus as well as UHC, OIII and Ha.

 

I plan on mounting a 80mm computer fan to the back of the OTA, adding a carry handle, 6x30mm RACI finder and a Rigel quik finder too.

Can someone tell me the inside circumference  or diameter of the Upper tube ring, please? I need to know how much Kydex I will need for my light shield. I am guessing somewhere in the neighborhood of 12" long x 48" around.

Kydex 24" x 48" is $18.95 on Amazon right now, in stock. Scopestuff sells it for $23. But, as Scopestuff is free shipping and Amazon is $5 shipping, it comes out the same, I guess. Just depends on when you want to get your Kydex sheet.

It's about 5-3/4" diameter at the narrowest spot (the factory light shield).

Excellent, that means that one sheet of 12" x 24" would be perfect for the light shield! I ordered two sheets, 12" x 24" from Amazon for $15.

Black Gaffers Tape for covering the Rivets on the inside of the light shroud: B&H Photo and Video: Impact Gaffer Tape (Black, 1" x 10 yd) $1.95 + shipping = about $5.45.

What size are the secondary collimation screws. I read in a post in this whole thread that they are M4 x.07, 25mm long?

 

Nevermind, I found the post about the secondary collimation screws. About to order some today.

I'm wondering how many OneSky's got sold this holiday season.,??.,nosey guys wanna know.,smile.gif.,

Hey Nosey! smile.gif 413 sold during December (395 ordered by Christmas Eve). Up from 204 in November. Dec. 2017 was almost double Dec. 2016.

 

A big reason is you, Dave, and everyone else here. People are delighted to have the community you have created behind the scope. You know what it's like starting out in this hobby without any help. You're shortened the learning curve for a whole lot of people. And, frankly, many of the answers I give to people who write in to us I've gleaned from the pages of this thread.

 

So here's to clear skies in 2018!

 

Mike

 

So, since AWB gets $95 from every OneSky for donation, you made about 40K for AWB from the sales of your OneSky Telescope in December? What are the other sales totals for January 2018 and February 2018 so far?
