Hi! I'd be really grateful for advice comparing these two GoTo scopes:
Celestron Astro-FI 6 inch vs Nexstar SLT 6 inch.
I've read a number of reviews for these online, and compared the specs. I'm not fussed about any price difference - and from shopping around, the price difference is minimal from some suppliers.
The main differences that I can see are:
- Eyepiece: 25mm + 9mm with AstroFi; 25mm and 10mm with Nexstar SLT (but over time I will have more eyepieces. While 9mm gives more mag, I know seeing and shakiness is more important than mere mag power so this is a minor difference, right?)
- Control: Nexstar SLT has no Wifi connectivity to the smartphone unless you pay £100 more,; instead it has a handset. Astro-FI has wifi connectivity and relies on an app on your phone/tablet.
- Weight:
a) OTA weight: SLT is 3.4-3.6kg; Astro-FI is 4.54kg??
b) Total kit weight: SLT is 8.2kg on one site, unknown on manufacturer website; AstroFI is 6.71kg?
Overall, diff websites say diff things about weight of these scopes, so it's hard for me to know whose OTA + mount/tripod is heavier than the other for transport purposes. Different stats all seem to contradict each other. Tripod weight is 2.3kg for both; one review said SLT 6 inch could be shaky on the tripod?
Otherwise both have F10, same basic focal ratio, same alumimium OTA, same OTA length, both have Starbright XLT coatings.
My queries are around comparing these two so I can pick one:
1) Smartphone v handset: I don't mind which I use, I'll go with whatever is best. What's the advantage to a handset - is it less buggy than wifi + phone?
If all else is same, no handset = less weight to carry given that I would be carrying a smartphone + battery back for the smartphone anyway when I go out?
2) Does anyone know which of these is more stable on the mount?
3) Weight-wise/transportation-wise, which is better? SLT has a handset whereas other one doesn't. SLT has ?lighter OTA though I'm sceptical about all these different weights quoted everywhere. Kit weight I'm not sure which is lighter overall. Does anyone know of the relative weights of both scopes/tripods for transportation purposes?
I should say I'm aware of the pro's and con's of GOTO scopes vs non-GOTOs, and want to go down a GOTO scope route here. I have previously used non-GOTO reflectors and binos so have had some experience in amateur astronomy. I have no desire to do astrophotography.
Thank you for your help
