Question: Does anyone ever used this as a carry on in the airport? I'll need to transport my 8se in a flight, so I need to decide between this and the big one.
Document: It is unfortunate that it is so big. I appreciate the compartments for accessories but it would have been better if it could accommodate the tripod. It is so bulky that you cannot have it as a carry on and I was not going to check in my telescope in a foam bag. I ended foam padding a regular carry on case and it fits perfectly plus it has wheels!
Large but protects the tube ok. Need a pack for the tripod. I have the 6 inch tube so i stioo have room for parts
I'll be spending 250 bucks pr more for a good Pelican case but at least I know it is secure and will take abuse.
I have not bought this item, nor seen it - this review is based purely on the stated specifications.The specifications for carry-on luggage dimension maximums are 22-inch by 14-inch by 9-inch (and these dimensions are not guaranteed to fit under the seat in front of you).
I purchased this case for my NexStar 8SE and when I received it was disappointed to find that it would only hold the tube. For all the other models (4/5/6) it will also carry the arm (which is what I really wanted). The shipment comes with a sheet describing it's use, I would recommend that Amazon post that information as well so that other 8SE customers could figure this out at a glance rather than finding out the hard way. Again, this is a beautiful case!
I have a Nextstar 6SE. This case is exactly what I was looking for to allow to transport my telescope to dark sky settings without fear of damage. Also protects it nicely from falling things in the closet. The scope fits nicely in the case with reasonable room for eyepieces and a few other accessories. Well made. Would buy it again.
Ok the case internally is well made and make sense. I gave the product a 3 because I travel a lot by air and the case has a zipper that will not take too much abuse. The case does not allow for locks to be secured to it. It's ok for putting it in your trunk, but there is no way I would use it to take with me on a flight. For this reason alone I give it 3 stars out of 5.
This fit my 6se pretty tightly....no way an 8 will fit. I had to lower the scope pretty close to the base to fit comfortably.
I did not rate it 5 stars because I have not examined any of the other stated features. If I could leave the review unrated, I would.
Usually I try to save money by substituting and cutting corners. I'm glad I bought the case intended for my telescope. Very sturdy, holds everything perfectly.
Answer: I have the 6SE and it barely fits. Also very little room for additional equipment.
