M100 shutter options

Is a wireless option possible for the M100? I didn't find anything in a search. And I've found that using a smartphone is problematic; apparently the camera drops the connection at random.

I realize you have an M100 but some of my information relates to the M200 as well. I'm not entirely sure about the M100 specs because it's no longer manufactured. But the M200 (which is the current version) has Wireless connection with the optional Wireless Remote Control BR-E1 and this pairs to the camera via Bluetooth. Since both cameras share virtually all the same traits, I'm assuming the same applies to the M100. Thus you can then shoot remotely from as far away as 5 meters (16.4 feet away) from the camera. When the camera is set for remote control shooting, the Auto Power Off Time can also be extended.

In addition, the M200 notes on the User Manual that "The Bluetooth Remote Controller enables remote control of the camera from a smartphone paired via Bluetooth (Not available when connected via Wi-Fi)."

I seem to remember that the M100 had a wireless capacity but that there were some complaints about the pairing and signal not maintaining a connection.

I needed an EF-M camera (for a Celestron RASA 8), and got a great price on the kit some time ago.

Any M-Camera will work fine but both the M100 and M200 have the smallest profile for allowing light to pass around the camera and into the Astrograph OTA.

I'm also considering the M100 as a replacement for my Sigma DP3M, which is getting cranky in it's old age. With the Sigma 56 mm lens, and Topaz Sharpen AI, the results are almost as sharp as the DP3M.

But with the rounded body edges, and the excessive pressure needed by the shutter button, I have trouble with camera shake. (And don't suggest rear screen shutter.)

Well, the Touch Screen shutter activation is how I use the EOS M cameras when they're connected to a long lens for astro or when attached to a Celestron scope... You can activate the self timer with just the lightest of touches, eliminating the type of vibration that button-pressing produces. If you have trouble with Camera Shake, then you need to be using either the Remote control OR the Touch Screen for shutter release.

Using an extender was pushing my luck, although it worked.

The Celestron RASA Astrograph telescopes were designed with both the Canon EOS M100 and Canon EOS M200 in mind, which is why they're shown attached to the OTA on the Celestron brochures. They have a light payload weight so they're ideal for mounting to the front window. For people who aren't already committed, the EOS M200 is the most recent (and currently available) model.

When using my own EOS M cameras attached to Celestron spotting scopes, I usually just turn on the touch-screen and activate the 2 or 10 second shutter delay. Touch the screen gently and... Presto! No more vibrations as you take your pictures. Usually the 2 second delay is fine, especially with a suitable EQ mount for your Celestron device. I tend to turn this feature off when not using the M-series cameras for Astro.

The M100 and M200 cameras are virtually identical. The M200 has DiGiC 8 compared to DiGiC 7 on the M100 but aside from this they have pretty much matching specs. Only the increase in the AF areas is notable on the M200. So you've got essentially the same camera with the same resolution and same size and function.

That's all good advice, thank you.

I've taken only a few pix with the M100 on my RASA 8. The sensor seems not quite perpendicular to the optical axis, but that could be operator error. I don't have a Bahtinov mask for focussing.
