Was wondering how many use a Newt. for AV. I know a lot of people use an SCT but I kind of am leaning towards getting a 4 or 5" newt with short fl at maybe f4 or f5. I'd like to use this with an SLT goto mount.

I could be wrong as ive never owned one but im sure i have read a few times the SLT mount / tripod are not great mate! Pretty flimsy apparently.

I've heard that too, but I think they may have been with the GM/LCM type tripod. The SS tube tripod looks more stable, like the XLT mounts. I don't plan on extending the legs all the way which will make the mount more sturdy. For visual they of course will be extended. I like the SLT for many reasons and one being that it can now be controlled by pc, with the right gear of course.

Your prob right about the type of tripod man i had no idea there were different types used.
On the PC control side of things... i cant speak for celestron. But i know for meade scopes and i think a few guys here have skywatchers...it seems the best way of doing it is actually to just extend the hand controller cable. As when for example using Stellarium software to move your scope around to different targets. Its not possible to make fine adjustments to centre the objects in your FOV. Making the whole thing kinda pointless.
There might be some software you could get that will basically replicate your hand controller. If there is such a thing for celestron then i guess it should work.

Chris most of that info I got from the internet and on the celestron site. Since I don't actually have this mount I can't really say for sure. The info from them says it can be remotely controlled per pc, how good I don't know. The mount goes for about $300 or less so it's not a bad deal. I thought about the SLT102 that has a short fl but not sure of the quality of that OTA.

The celestron can be computer controlled im shure..I use the skywatcher eq3/2 pro and use it with the eqmod mine is bluetooth controlled. .this combination is brilliant like night and day compared to the handset..much more control. . Ive used my eight inch newt on the eq3/2 with legs in low position, its ok for astrophotography but cant focus with an av camera,, you may require something like the skywatcher quatro it is a shorter focal length scope.

I use the SW 150p F5 on a eq3/2 GOTO and works great. The only problem with newts is reducers are not easy to use due to the required inward travel. It has been done. The cams work well around the F5 mark.

I took this image with this exact scope on a celestron nexstar se mount, with a sdc-435 samsung camera.

That's a great image of the flame and horsey hemmi.
I got a focal reducer to work with my newt. I had to use a 2" c-mount adapter instead of the 1.25" c-mount adapter. So it can be done.

I can't get anywhere near that amount of detail on the Horsehead. I'm assuming that's an 8s exposure (512x). If the small Orion reflector is that much better than the 6"SCT on my 6SE, I'll buy it in a heart beat. Could you share your camera settings for that image?Thanks, Kim

Sorry about the above post. Guess I don't know how to reply with a quote. The first sentence in my post, as well as the image, are from Hemmi

At this ratio it really pulls in the light.

wow that is an awesome image. I'll have to check on some rings and dove tail bar for that OTA.

You probably won't be able to get that newt below f3.2ish without the image suffering.

My bad. I wish I could get my scope down to f2.25. Maybe I should invest in a better FR. Would a better FR have better quality? I have a 0.5x GSO, but the reducer sits closer to the chip than what it should to achieve the 0.5x.

I have a 6.3 fr and a .5 fr on my 6SE. I assume that gets me to around f 3.5 or 4 on this scope. What are you using to get such a fast f ratio on the reflector, Hemmi?
Thanks, Kim

The IR filter was also removed from the sammy.
