Have you ever tried "Precise Goto"? It works great and is built into the Celestron mount. It's not documented in the manual that comes with the scope but it should be there.
You get to it with your "Menu" key instead of using the "Deep Sky" key. You'll be presented with a list of 5 brighter stars near the object of interest. They're usually bright enough to be seen with a red dot finder. Put the scope on the star using the finder then center it in the camera. Then press "Enter". The scope will slew to the object and usually put it in the camera's field of view. The menu key on my 130SLT is the #7.
Here's a video tutorial of it:
No, I wasn't even aware of it. The operations manual only makes mention of it on the hand controller menu tree and I wouldn't have known to look for it if you hadn't mentioned it. Thank you.
Errr no. Even if you absolutely dead centered your alignment stars, the GoTo's would still have some errors. It's an unfortunate result of the combination of gears, motor pulses, and the software which has to do some freaky calculations to it's internal star map whenever you do an alignment.
The "sync" function is done totally separate to the alignment process, and is specifically designed to help you find stuff in those areas of the sky where you have done a goto, but due those gear/motor/calc errors you cannot see the object. If you slewed to an object and its in the FOV of your R2 then you wouldnt do a "sync" on it.
Read the manual. Cos what I said is true ... no matter how good an alignment you did there are always going to be goto's which are not in the FOV. The "Sync" will help save you heaps of frustration.
There is no reference to a "sync" function in the operations manual, but it's probably just called something else. I haven't been able to get any scope time since all these helpful suggestions have been rolling in, but hopefully if there's no fog tonight I get out there and try some of these suggestions.
I still reckon you should be able to get stars near centre of screen with good polar and star alignment. I could do that on my old cg5 with a C8 and RI or 224 camera.
Maybe repeat the polar and star align a few times. I either
1. Polar align with sharpcap. Then do star align (2 align stars +4 calibration stars). 2. Star align but on the 1st star centre it with alt/az (Howie mentioned this). Then polar align with the handcontroller. Then repeat star align.
With each star roughly align with finder scope and then centre on camera. I usually do (1) these days. And I don't have my mount in a fixed spot. I practiced this on those moon filed nights
Hi Marty, I downloaded the Nexstar Evolution manual, and it calls it Precise Goto ... so look at the other post by robrj in which Robert had put the link /videolink on how to use it. Same thing as 'sync'ing only called Precise GoTo. Hope you get to try it out soon .
