wide field views for skimming for objects to get closer to with the mak could use a bins something like 8*42 binoculars

A single frame as JPEG might be easier to see as the stacked image may have rounded the stars, though to my limited awareness the corners aren't obviously off for that camera.

Was a driver supplied by svbony for your camera?

My canon T2 is 10mm.

For @NGC_Mike this thread on imaging with your mount may help whilst waiting for a reply on your question

https://stargazerslounge.com/topic/348979-imaging-with-an-az-gti

Had the micrometre out again and my T ring measures 10mm so I'm using two homemade .5mm spacers and I've screwed the flattener to the evoguide to eliminate any tilt. Here's hoping for a clear evening to try again.

If using your telescope during the day be very careful not to point anywhere near the sun. 

The planets are quite low in the sky so you may find they do not resolve very well as you would be looking at them through a lot of atmosphere. Stellarium is a great planetarium to use to find where different objects are.

Altaz mounts do track but in tiny left right up down movement which follows the target object but not the rotation of the object. The longer the image exposure the more rotation of the object that occurs, so with an altaz mount at some point (can be in seconds depending on size of telescope) the target becomes smeared, the image edges are hit first but the whole image eventually.

Altaz image taking is possible but you have to work within the limitation of such tracking. It's about what your expectations are on what you want to achieve on DSO. Planets/Moon less impacted as short videos of very fast frames are used. The star discovery does not come to focus with a DSLR. The virtuoso v2 with a 150P flavour in theory would as the truss could be left not fully extended.

If your viewing is from a nearby field you may want to consider what equipment is practical in size and weight for you to use, this also includes storage location to using location. Portability is very personal to individual situations.

hi details are here

Thought I'd add as I have a mk1 I made my own version of the new style mounting bar. 

There is a starizona flattener it will be their v2 which works with a DSLR they are super slim

sorry for slightly drifting this post

Could I ask please, is your T ring exactly 11mm as I can't see a spacer on your rig?

I'm having to use homemade plastic washers to make my distance 55mm as my T ring is slightly thinner than 11mm.

Gosh it is very close, Friday I tried 1.2mm spacing (.5+.7), here's the composite from four 1 second images on a AltAz tracking mount. I haven't decided which is better as neither are obviously either too close or too faraway. I will double check that those were the two spacers I used.

I would not worry about edge distortion as you are using a static mount you'll crop the stacked image edge's due to field rotation

you can get a red dot finder that mounts in the camera flash hotshoe, helps with where the camera is pointing. get a remote release for the shutter or see if DSLR Controller an Android app will work with your canon as it helps hugely with focusing too, though you need an android device

how small is small? came out well 

lovely one, your focus looks pretty good. Quite amazing you can use 45 second exposures, I get trails with 25 second exposures and I would have thought our setups were not that different assuming you are using the 178MC

We had total cloud so I didn't bother setting up

I think as atmospheric conditions I've found influences star bloat you'd have to test on the same night the different ISO on the same target.

You've been busy with your clear skies. Why not do a stack combining your two sets of Orion data, though what you have so far has come out well, the previous image is showing slightly more clouds.

Skyywatcher do an L bracket for attaching anything with the tripod screw like on a DSLR like this one for example

Lovely comet. SIRIL will stack comet images.

Sounds a memorable observing session and with speedy binoculars.

You might like watching the recorded zoom StarGaZine sessions from last year, there were plenty on different aspects of astrophotography

There's a forum section on all the sessions and a YouTube channel

It is possible to manually mark where stars are on your reference frame, this I've done when not enough stars were found. It's the same tool that you'd use to mark a comet.

Have a look at the bleeding edge version as you might find it moved.

I think magic lantern may only be usable on the original canon m mirrorless, though I haven't researched recently to see if later models are supported. Canon were better supported with various astro software then the others though the third party software support has got better than it was I gather on the others. Sony and Nikon both had star eating issues and longer exposure length limitations linked to it, you'll have to research to see how much this applies now but if buying second hand it would be worth knowing what it means for the models looked at.
