Deep sky viewing is so much easier!

I love my evscope! I heard about it when it was in the kickstarter phase and I’m so glad I purchased one. It’s amazing to have deep sky photos right on my phone without needing the separate software to process them. The only thing that could make this better is if they developed the app to work on laptops so you could get larger images. The images are great on your phone but they don’t look as good on larger screens.

For the developers: I don’t know how to report app issues but I seem to be having an issue with the enhanced vision feature ever since the latest update. When I use it, after 16 seconds I get one of three messages: enhanced vision dropped, enhanced vision dropped check bubble level, enhanced vision dropped vibration detected. However, it’s still in enhanced mode it’s just not capturing anymore it seems to be frozen at the 16 second mark. I have to turn off enhanced vision manually or it stays stuck there. The pictures save only after I manually turn it off and not when I get the enhanced vision dropped messages. I make sure the telescope is level, on solid stable ground, and I don’t let anyone walk within 4 feet of it. This started after the latest update. I tried uninstalling the app and reinstalling and I make sure I upload the data from the scope before each use. Any help on fixing this would be greatly appreciated! Thanks!

Love my evscope.

I was an early adopter and ordered my scope durning the kickstarter. After waiting very impatiently for my telescope, I was rewarded with views of the sky that I only dreamed of with my previous telescopes. I absolutely love the design and capabilities. The only problem….. it makes me want more. The ability to see nebulas in full color, star clusters, planets and more has been very exciting for me and I’ve had many compliments and wows from friends and strangers.
So far the software has worked quite well for me. I’ve not experienced any issues. The addition of the planet mode was a welcome addition, and now being able to track the sun is a cool plus too.
I’d like to see a few additions that shouldn’t be to hard to add in future upgrades.
*I’d love to be able to store custom targets. I navigated to an Einstein Cross, which took a good bit of star hopping. It would be awesome to store that target for future viewing.
*Also adding a mosaic mode would be a long awaited addition. It can be done manually, but is a lot of work stitching the picture together.
*A picture editing feature built into the software would be nice. Not necessary, but it’s nice to stay inside the one program when you can.

Thank you so much for your review! Unfortunately, those additions are not easy to implement, but we will try :) Best

Makes astronomy accessible

Love my evscope. It makes astronomy accessible as as a hobby for anyone. The app is fantastic. Three problems it has is: (1) it kicks me out as being the operator several times an hour even though I don’t have guests who are trying to share my scope; (2) the Wi-Fi connection between my scope and my phone is not stable and I have to reconnect a lot; and (3) the overlays placed on the images often misidentify the image as being whatever celestial object I am currently slewing to.
