Review: Un tubo guia increíble - Como tubo óptico es Impresionante, mejoró mi sesión de astrofotografia a buen nivel. Unas capturas qie hice con este tubo óptico y una zwo ASI585MC. Un tubo óptico recomendable si vas comenzado en astrofotografia, requerirás aplanador
Review: Great guild scope and occasional imaging telescope. - I got this for a guild scope, but it also works great with the Starzona field flattener for a lightweight imaging telescope. I found a 3D printed setup that clamps the scope and holds the mini computer, guild scope, and EAF focuser. There is a lot of backlash with the focuser, and I haven't gotten auto focus to work with this scope yet. There isn't enough backfocus adjustments to use with a star diagonal. I have also used it for electronically assisted astronomy with a camera attached, and with my ASIair for a go-to visual astronomy.

## Features

- EXPERTLY MATCHED GLASS: This small, lightweight 50mm f/4.8 Apochromatic Doublet refractor uses expertly matched ED glass to deliver dramatic, coal-black skies and faithful, contrast-rich views
- MOUNT ANYWHERE: The EvoGuide 50 DX includes two mounting adapters: a machined aluminum finder stalk compatible with all Sky-Watcher finder brackets, and a V-style mounting rail

### ⭐⭐⭐⭐⭐ Awesome budget friendly telescope for astrophotography
*by A***F on 25 November 2023*

First if you don't have a tracking mount, I would suggest making that your priority over the scope. As a guide scope it is overkill, but for astrophotography it is a great cheaper option to a Red Cat and works great with DSLRs, mirror less and astrocams as long as the sensor is a APSC size of smaller. Also a very important note if you purchase a Field flatener (a must to really get the most out of the telescope) do not buy the skywatcher field flatener unless you are using a dedicated astronomy camera only as they do not have the required back focus for a DSLR or Mirrorless camera. For the back focus for all camera models it will require the Starizona EvoFF flatener and with the flatener in place it jumps the focal length up to 258mm. I suggest this scope to anyone getting into astrophotography simply because it can be a very expensive hobby and this scope is a great wide field scope that is nice and compact and portable that can be used as a guide scope with future setups, which could be done with a Red cat but at a fraction of the price. In the photos, Andromeda and the North America Nebula were captured using a unmodified Canon T3i (600d) and the Dumbbell nebula was captured using a ZWO ASI178mc planetary camera, as well as a photo of the complete imaging rig. Cheers and clear skies.
