I have no personal experience with either mount, but I think you will find much more information about both in the forum devoted entirely to mounts at cloudynights: https://www.cloudynights.com/for ...

I don't think most of us pay much attention to the brands of our adapters, and I only occasionally see posts from people complaining that some they bought from this source or that didn't quite fit ...

I confess, that's never occurred to me. But I'm doubtful. I also don't know what red dot you mean, since there is none in the live view of my own cameras. A very healthy amount of magnification is ...

I'm mostly a Newtonian user, and IMO, while precise collimation is important, its difficulty is grossly exaggerated. It does not require any special tools. All it actually requires is an eyepiece ...

There are perhaps some exceptions, but for most cameras and astro targets, manual focusing is absolutely essential. It requires a steady hand and a steady tripod. Lots of cheap tripods aren't up ...

Yep, you muffed the math a bit, but most AP newcomers do. You can't make light-gathering comparisons based just on the varying f-ratios of lenses with different focal lengths, which I think ...

I'm hesitant to ask, but your earlier post revealed that your images to that point had been hand-held, and I still haven't noticed any mention of a tripod in your posts. Also, your post in the ...

Definitely Arcturus. Beginners are taught to find and identify Arc turus by following the "arc" of the Big Dipper handle. It's a 1st magnitude star, much brighter than the Dipper stars, and made to ...

This seems to call for a wheel I'm not capable of inventing, much less re-inventing, but there are many discussions of the relative merits of those two cameras ready for your review on the cloudy ...

In case it's not clear from other responses, the "Minimum shutter speed" found in the DPR specifications is the maximum definite duration setting, without using the "bulb" function. What often ...

Unfortunately, whether color or monochrome will work better depends on what you're imaging. Monochrome sensors are more sensitive, but planetary imaging is generally best done with video, and ...

The closest approximation I've found so far in GIMP 2.10 is Filter>Distorts>Value Propogate, with the "Mode" set to "More Black." Following Rudy's tutorial and using that filter in place of ...

Rudy, thank you for preparing and sharing this great little tutorial. I've been trying for months to get that effect, pretty much using the very same PS functions. Without benefit of advice on the ...

Mostly, I just charge up several batteries for my Canon and Pentax DSLRs. As OllieN has already noted, a couple of DSLR batteries generally last through a long a session as I need. Recently, ...

Being ridiculously frugal, I'm a big fan of Newtonian reflectors. Aperture can't be had more cheaply. As many of you know, however, Sir Isaac's design is plagued by coma, an aberration that ...

I haven't used that specific filter, but it seems to be just a Bahtinov mask made to fit a square filter-holder. I've been making and using Bahtinov masks for several years on telescopes, and they ...

I wouldn't advise the OP to give up on his current HS50EXR. It's obviously far from ideal, and don't think he's likely to achieve the equal of that image Swims posted above, but this 2013 Fujifilm ...

Celestron says nothing about the shape of the mirror on their product page for the AstroMaster 130 but their "knowledgebase" page contains the following question: "Does my AstroMaster 130 have a ...

The Newtonian telescopes in that Amazon listing might be usable for some basic lunar imaging, because you don't really need tracking for that. But it's not likely to be done so simply as you suggest. ...

I can't tell from your post whether you already have one teleconverter, or are just thinking of buying one, but have you considered using more than one? Good TC's can be stacked (see, e.g., Roger's ...
