Just buy a 'hot shoe red dot finder'. Its the tool for the job, lasers for home astrophotography are not needed ever and people like yourself misunderstand the point of them at all in astronomy. Its just not the right tool. Easeus data recovery wizard for mac free 9 8 bit. Anyone have experience mounting a finder scope/autoguider (Orion Deluxe Mini 50mm Guide Scope) onto the hotshoe plate on the top of a DSLR camera? The finder scope has a 1 1/4 dovetail base (shoe) and also a adapter plate but I need something with a hotshoe fitting on one side and a plate or a do.

Hi all.
A couple of yrs back I purchased a decent quality green laser pointer to mount on my (hopefully soon to be sold) 8se to take the place of the finder scope. Never got around to doing so I pondered on the thought of using with my 70d.
I posted a thread on cloudy nights sometime ago asking if it was safe flash through the view finder to make targeting easier when selecting object for widefield AP with my iOptron skytracker? Never really got a definitive answer. As couple of ppl suggest it was fine and a great tactic for the mentioned purpose but live view MUST be deactivated to be 100% safe. Others said bad idea don't do it know of others who damaged sensors etc.
Anyone here use the method or know it to be a safe/practical method?
Cheers for reading,

Most digital cameras these days come with some kind of electronic remote shutter release. Various solutions exist, using USB cables, smartphone apps, or dedicated remotes. [Steloherd] wasn’t happy with the options available for his Ricoh GRII, though, so built a rig to do things the old fashioned way.

[Steloherd] wanted to use an old-school mechanical release cable, so devised a way to use it to trigger the Ricoh’s standard shutter button. A small aluminium bracket was created, attached to the hot shoe on top of the camera via a mounting foot from a standard flash accessory. A spring plate was then created to help spread the load from the mechanical release pin, ensuring it triggers the camera effectively without damaging anything.

Installing the mechanical release proved difficult, as the DIN standard calls for an obscure M3.4 conical tapped thread. Rather than muck about finding rare tooling, [Steloherd] simply recut the thread on the release cable to a straight M3x0.5, and did the same for the bracket.

Overall, it’s a tidy hack, and one that could be adapted to other cameras fairly easily. Other methods we’ve seen involve such odd choices as linear actuators harvested from air fresheners, if you’d believe it. As always, if it works, it works!
