You could take about 6 shots at 10 sec and stack those= 1 minute of exposure and less or no elongated stars. orion is fairly brite. A reducer/corrector would also help by reducing your focal length and ratio.

Thank Astro I've been looking for that excuse to get that reducer/corrector.
It should also get all of Andromeda and Orion into view also.

See if they will substitute the 55-300mmVR G for the 55-200. Call them on the phone. They are very helpful. It may cost a few extra $$$ but you will appreciate the extra reach.

Agree, I used my 55-200mm for 1 shoot and sold it and got the 55-300mm like I should have in the first place.

Don't think stacking will help with telescope drift it may be polar alignment, gear backlash or movement elsewhere during exposure that's producing elongated or double stars. I keep iso 1600 or lower to reduce image noise.

@ 1600 how long do you expose for?
I'm stuck with f/11 on the scope
Do you use a Flattener or Reducer to get lower F Stops

Either way wonderful image round stars and great nebulosity. What was the exposure time?

Thank you Astroturf,
The 2nd Andromeda Galaxy
30sec. f/9.5 ISO 3200 Manually pulled information out w/Lightroom. You would think it's a long exposure but it's not.
Feeble attempt at stacking, see all the double stars (Telescope drift). What I am after with this is the reality of the colors.
It's hard to know because of all the different photos out there.
I'm not done yet, I will get it right. I was hoping I could get some help from you guys here at APF. Settings, filters & PP.

For all practical purposes they are identical. The Tamron, being on the market longer than Kenko, is more available used.

Thanks Imagemeister

But, you can use the Kenko Auto Pro extenders on almost every Nikon tele, especially the ones without silent wave motors.

Also the Tamron Teleconverters can fit all the Nikon lenses.
Which is better the Tamron or the Kenco Teleconverters???

It will be quite difficult to find a quality Nikon tele-converter for 150 bucks. One the other hand, the new 80-400 is a great lens. The older was fine optically, but the focus for sports and wildlife wasn't there.

Be careful what lenses you want to put Nikon Teleconverters behind.

That's what I thought for the cameras.

Lenses still have paper.

The sales receipt has the Serial Number on it. Make sure you have that for any warranty.

If you are willing to risk $150-$200 and have problems with focus in your type of photography you describe, then go for it,
on the other hand, if you are not the adventurer and want a sure fire deal, then go for the longer zoom ! :)

I only use my Teleconverter for static shots because of the AF issue.
I almost always, on a Long Zoom Lens, can't get an AF lock on a moving subject in medium to low light.
