Hello cloudy nights,

I would like to know more details about the EXOS2-GT mount like cons pros and what can I astrophotography with it

I am on tight budget and would like to know what is this mount capable of doing in regards of astrophotography and if you have any images taken with the mount please share.Best regards,

The video review is for the PMC-Eight controller version of the mount which costs $899 not the $499 version used in the FirstLight series.

I have. EOS-2 GoTo mount with an Orion 8"f/3.9 reflector w/Canon 6D. So it's a wide field scope. It's an adequate mount but if you have a more narrow field scope I'd look at a different mount.

thank you for the advise I would like to see some of your astrophotography with the mount

I started this thread a while back to kind of keep the standard EXOS2-GT mount information a little more centralized. I'm only starting to get into AP and I'm only a beginner with a lot to learn. Unguided, I can do about 2 minutes max (and easily do 90 seconds unguided) and the stars stay round. I think if you kept the exposures under that, this mount would do fine. Over that maybe the ST-4 guide port is the route to go. I'm not into guiding yet.
These were taken with my OMNI XLT 150mm reflector and my DSLR on my EXOS2-GT. I'm just experimenting with exposures, stacking, etc. from a very light polluted backyard. These pics below aren't stacked.These are just single 30 second exposures of M31 and M57. Obviously I'm a newbie to AP, but these pics only reflect my photography skills, not the mount. I've taken 90 second and two minute exposures (of just stars) just to see how long the mount could track without the stars being affected.
M31 - not near enough exposure time, and I really need far more subs and stack them. Still learning...
M57...
Besides my heavy light pollution, the moon was out which didn't help, so I took a few pics of that too...

What telescope are you planning on using on it?

hello ImNewHere,

I have a mirror lens 900mm f8 on Nikon D3400 for start but my plan is to get 6" relflector 150/750 and start my AP
I need to know how much exposure I can do guided and un guided with the 150/750 and will those exposures are enough or do I need to stack and do flat bias and dark images letting you know I live in a polluted area.

Regards,

Mark Dominguez

which telescope did you use for those pics? amazing job, my expectation was much lesser then what you showed me, any other pics you would like to share?

good job

What other lenses do you have? Also, yes, you need to stack. You will also need a coma corrector for the reflector. What is your telescope budget? How badly light polluted are you? What do you want to image?

With what you plan on using you might get 1 minute unguided. It will work, just take loads of subs.

Conventional wisdom is smaller refractor with no more than 600mm to start. I mean you can image with what you plan, but it might be harder in the beginning. Also, you will need darks, flats, and bias.

I live in a dark area and I definitely stack, sometimes hours worth. Even bright targets should need 30 minutes minimum to average out noise and bring up detail.

I'm waiting for @bobzeq25 to come in here.

Thanks. I am a total amateur with AP...just starting to get into it. I also live in a ton of light pollution so I'm experimenting with ISO and exposure time, as well as just learning how to stack, etc.
I used my Celestron OMNI XLT 150mm f/5 (750mm fl) reflector on my EXOS2-GT. GREAT scope for visual and imaging...only 12 lbs. with a 6" mirror and the price is great too (High Point Scientific is the only place that sells the OTA without the mount) $240. I replaced the stock focuser, but others do well with it. My EXOS2-GT can do up to about 2 minute subs without guiding to keep stars round. Here's a pic of my setup on my first night imaging (those pics I took were the first images I ever took of DSO's...so I have a lot to learn). I don't have anything else at the moment...I haven't had as much time lately and now the weather sucks.

You will definitely need to stack shorter exposures. No getting around that. I deal with a lot of light pollution as well. If you are polar aligned well and have everything well balanced I think you could safely do 90 second unguided exposures at ISO 800. I'm just experimenting now with ISO, exposure length, focusing with a Bahtinov mask (no live view on my DSLR either...ugh! LOL).

It's a solid mount that will work for shorter exposure imaging. You can't control the mount with anything but the handcontroller (other than the guiding through the ST-4 port) as there is no active interface with a computer otherwise. I don't even use a computer when I image. I just power the EXOS2-GT with a 12v Talentcell li-ion battery and I use a wireless intervalometer on my DSLR so I can program the number of exposures and length and take photos without ever touching my camera.

Someday when funds allow, I'll upgrade to a better mount, but for now I can learn a lot about AP with the EXOS2-GT.
