Finding objects in finder?
Posted 26 July 2014 - 09:12 AM
Took out my XT8i last night for the first time. My problem is, I can see the object with my naked eye, but then it takes what seems like forever to get the object in the finder. Even trying to get Vega in the finder was tough for me even though I could see it right in front of me! Frustrating and embarrassing! Any guidance/tips would be greatly appreciated. Thanks!

Also, of course, make sure the finder is aligned with the scope. Did you already do this?

If you haven't done so already, set the finder to match the eyepiece view on a easy target like the moon or in daylight on something distant and small. Then from behind the telescope try aligning the OTA left/right as best you can on a star or planet. Sweep slowly up and down and with a bit of practice you'll get there.

It's all about experience-in a short while, after a bit of training, you will have no problem finding objects with the finder.

Double-sided adhesive mounting tape gives you a sturdy yet reversible way of attaching your auxiliary pointer---In case you later change your mind.

I've always used a straight through finder because I can't stand a right angle where I can't see where I'm aiming. Back in the day, I was using a 30mm and it might as well have been a gunsight anyway.
Today, I use a green laser pointer which is the best thing since sliced bread, as far as I'm concerned and excuse the cliché. I almost never use the regular finder. Almost everything I look for is way too faint to see in that 50mm finder anyway. The idea is to aim for the approximate spot and mow the lawn. Half the time, I'm almost dead on anyway.
Practice makes perfect. I get to where I don't even like to use the regular finder if I don't have to use it. A necessary evil, more or less. But I do when I have to and have decades of practice with it. That's what you need, Davidsonville, just practice. Just like star hopping. It's a skill not a talent.

I've owned dozens of scopes over the years and done tens of thousands of hours of serious observing at the eyepiece and never once desired to have a scope equipped with a right-angle, red dot, nor Telerad finder. I and many other observer friends have found that the basic straight-through finder works far better for locating objects in every instance. If the object is visible to the unaided eye one simply needs to keep both eyes open initially when looking through the finder. That way the observer sees both the nakedeye view, plus the finder's crosshairs projected on the sky at the same time. Alignment with the objects becomes almost instantaneous! Once in the finder's field, the observer need only close the eye not at the finder to make final alignment on the object. This approach works equally as well for objects visible only with the aid of the finder if you have a knowledge of where objects are in general within the constellations. Honestly, I don't know of any really serious observers of comets and variable stars who employ either right-angle finders, or Telerads.

Different setups for different scopes and observers.

This is obviously a generational thing, since most people who started observing before the unit-power finders came along prefer straight-through finderscopes, and almost everyone who started observing after unit-power finders came along prefers either a unit-power finder, a laser-pointer finder, a right-angle finderscope, or some combination of the above.
I am perfectly content with any or all of the above, and I have also done my fair share of finding objects by sighting along the tube of the telescope. But barring any constraints with respect to cost, size, or real estate on the tube, I would choose a Telrad combined with an 8x50 right-angle correct-image finderscope. That gives me the greatest number of different possible techniques for different situations, combined with the greatest comfort.
Very likely if I wasn't so conservative I would prefer a laser-pointer finder to a Telrad.

This is why i made my setup to include the RACI and a Reddot, as well as a laser finder(it covers all the bases except for a straight through finder, which it seems to me would cause neck/back issues for me).
as a sidenote my RACI has been rotated so that the eyepiece of the RACI is parallel to the focuser so i only have to move up an inch from the focuser to use it.

The problem with the laser pointer is that you always have to be careful that they are not pointed accidentally at aircraft or you will get an unexpected visit from the police.
Assuming that you turn it off when not in use -- which is a good idea anyway to save the batteries -- I would say the chance of this is essentially zero.
Airplanes are very small targets and laser beams are very narrow. Pretty much the only way a laser ends up shining on an airplane is when somebody does so intentionally.
The main reason I don't use a laser-pointer finder is that I find them aesthetically unappealing -- though I do use laser pointers for showing stuff to other people. And I don't particularly mind bending my neck for the few seconds required to sight through a unit-power finder.
Bending my neck for the minutes required to do a careful star-hop through a finderscope is a whole 'nother matter. Plus finderscope allow much less leeway with respect to where you can put your head.
