Designed & manufactured in Japan, the 77mm MM4 77 GA ED Spotting Scope from Opticron, featuring the HDF ED optical system, delivers a new benchmark for resolution and color contrast and comfortably outperforms older Opticron 80mm models. What is more remarkable is the size and weight of the overall package. The MM4 77 GA ED is just 12.4" long and weighs 44 oz fully armored. These figures read like a 65mm, which cannot deliver the light transmission or apparent resolution of this 80mm class device. Compatible with SDL, HDF T and HR eyepieces, this scope allows existing owners to use eyepieces from other Opticron models.

Q: 1. Hey there,Questions...1. Can you attach this to a DSLR camera?2. I noticed there are some 1.25 lens attachments that have extra zoom... maybe a stupid question, as I'm buying this as gift, but does that extra zoom, give you an overall further zoom on the scope? We're looking at this for a travel astronomy telescope.thanks!!

A: To answer your questions.1. Not as it comes out of the box. It is possible to attach this to a DSLR but you would need an adapter to go from the 1.25 on the scope to whatever lens attachment your DSLR uses.2. With this scope you have to buy an eyepiece. The eyepieces come in fixed power and zoom from a variety of manufactures. Any zoom lens is going to have a certain range of magnifications it can produce, for example if it can zoom from 2x to 6x the lens is capable of a 3x zoom (this is a non-technical way of stating this). If another lens can zoom from 2x to 10x it has a 5x zoom. An extra zoom, sometimes called an extended zoom, sometimes called an wide range zoom, will generally give a wider range of magnifications than a standard zoom. To find out what magnifications a certain lens will provide you need to see what the minimum and maximum points it will produce are. These are not given in powers magnification since that varies depending on the objective size of the scope so you either compare mm points if they are in the same general area of magnification or do a bit of math to see what they produce when mounted to this specific scope body.Hope that helps. I use mine for travel astronomy as well as for land use and am quite happy with it.

Q: 2. working temperatures ?

A: Buy a high quality fixed eyepieces such as the ones referenced above. Stay away from zoom eyepieces (image quality is not as good, in my humble opinion. Spend more money and get several fixed eyepieces--one that will let you get you fairly close and that will provide a wider field of view, and one that will enable you to get much closer and that will give you a much narrower fov. With this scope, you should have no problem using a high power ep to get up close and see great detail. (Also make sure you get and use a very sturdy tripod.)

Q: 6. I have a Nikon D610, what kind of adaptor I can use to attach it to Pentax PF-80ED-A? Thanks.

A: As I have a Pentax DSLR I bought the PF-CA35 which replaces the eyepiece and is Pentax k-mount direct to the camera body. I think you can then get a k-mount to Nikon ring and that might work, hope that helps some
