I don't mind using the supplied 1.6X Barlow. It save a lot of potential heartache if something goes wrong.

This is true! also the .6 of amplification is mostly needed.
I have to use very high power EPs on the Sun anyway.

I also have a Siebert bino optical corrector power wheel that works pretty good with an objective solar filter .

I am using an Astrotech 99% dielectric and the stock focuser. It's ok and not keen on spending $150 for a new 10:1 focuser.

Hope you have good weather to try out your WO BV tomorrow. Perfect timing with the 1st. qtr. Moon!




Thanks! Is the Astrotech a 2" diagonal? Perhaps with the GSO and Baader T-2 I can focus without the WO barlow. Or then again, perhaps not

Oh yes, the Moon! Been hearing about lunar 3D viewing with a binoviewer since I got back in the hobby. Trust but verify

Well we got clouded over last night and was only able to get a quick glimpse of the Moon in my BV and it looked great. With the 26mm EP in them I was just able to get the entire moon in the fOV which would make it a half a degree. With the 1.6x in it, the power was about 100x.

Hope to try it out on Saturn this weekend before it sinks over the horizon.

Bob

No it's the 1.25" model. No you need the barlow to focus. It's not too bad, I tried it for the first time last night. I had to add 3lbs. to the end of the tube to balance it.

Too bad Siebert doesn't make them any more ... or does he?

Do you think it will work OK on my Nexstar 5SE mount? I can't remember if the Nexstar controller has a way to change the telescope type (I always get it and Autostar mixed up in my mind). If not, I'm afraid it might 'hit bottom' if I tried for objects too high up. It would be nice to use it with the SE mount, though, instead of lugging the beast LX80 (hopefully soon to be LX85) out.




Someone found a solution.

I made a little animation of Jupiter using the NexImage 5. The violet really isn't too bad.

Steve,

Those are beautiful pictures!

Other than the neximage 5 did you use anything else for those pics (like a barlow)? What mount?

I'm thinking of getting a camera so my young kids can more easily see. They can't seem to get looking into the eyepiece, especially without bumping it.

Nice shot Steve!...about the level of CA I see at the eyepiece with similar detail on the disk.

I did not use a Barlow or anything else, just the NexImage 5. I posted a picture of my CG-4 mount here.

I now have the motor option added to my mount. Earlier I posted a picture of Jupiter I made without the motor. I explain how I did that here.

Jupiter doesn't look this nice on your computer screen. What you see looks more like this.

Thanks!

We had it out this morning looking at jupiter. I could clearly see the darker streaks, but my kids couldn't.

I realize that you are doing some post processing on the pics.

Thanks for posting the before shots and your mount. I missed those posts. It might be time to get a neximage 5!

I don't want you to buy the NexImage 5 and not be able to use it without spending way more, so here is something to consider.

The field of view with the NexImage 5 is small. In the 640x480 mode which I used for these images Jupiter drifts across the screen in 20 seconds. You can switch to a higher resolution but then you have to shrink the image to fit on your screen, then Jupiter is smaller.

What this means is that finding and keeping Jupiter in view is a challenge. If your mount isn't tracking then Jupiter will move out of view between finding it with a wide angle eyepiece and swapping it for the camera. I have the 9x50 viewfinder with cross hairs which helps me find Jupiter with just the camera. I have slow motion controls to turn the mount (and now the motor option) and being equatorial means I only have to turn one knob.

The NexImage 5 camera is fantastic and I would like everyone to be able to have fun with it.

Excellent images from the C102! Not so different from what I can see through my 10" Dob on an average night ... without the slight violet fringe.

Thanks for the tips! We'll start with the neximage 5 and go from there.

Yes though lately Jupiter has been kinda brown or sepia. I have gotten more color with my NexStar 5SE. This picture shows both Jupiter and Saturn taken with my 5SE. Saturn tends to have more color.

Great image and color contrast. I see a similar view with a yellow #8(to lightly reduce CA) at 200x
