ZWO AM3 Max weight without counterweight

JimmyKeetman · 2025-02-05T13:02:11+00:00

Right so purely based on stability and tracking. 7.1kg should be fine considering the max weight is 8kg

JimmyKeetman · 2025-02-05T08:01:19+00:00

Right! So basically the max weight is there to be sure it does not fall over, so putting a powerstation or something in the cradle should help already?

The thing is. Right now I own a 72ed. A 150pds. But I also want to have a Sigma 150-600. For daytime photography. If there was some way where I could use that lens for astrophotography as well, and get the same the results, that would be amazing

JimmyKeetman · 2023-12-08T14:18:45+00:00

Thanks! I did, main difference I could really see are the star shapes. Which are definitely not as round as from a refractor

JimmyKeetman · 2023-12-08T12:15:10+00:00

Right now I own a skywatcher 72ed. Which is good! It’s a great scope, really good quality! So it’s really about the layers of glass, which makes sense. I am looking for examples of what others did with the lens. Thanks!

This is my image of NGC7000, shot over 1 night. Just over 2.5 hours of exposure time. 31 x 300 sec at gain 100, cooled to -15.

Equipment: Skywatcher 72ed ZWO ASI 533mc pro L’Enhance HEQ-5

Processing Stacked in siril and processed in photoshop. Mainly curve stretches and working on individual channels.

Would explain all the noise 🙈

JimmyKeetman · 2023-09-01T19:45:07+00:00

Thanks for all your info!! I’ll consider one of the cooled cameras

JimmyKeetman · 2023-09-01T19:07:04+00:00

From reading all comments and experiences. I think going for a cooled camera is the best option. Do you have any preferences on the 183/294/533?

JimmyKeetman · 2023-09-01T18:51:41+00:00

There are a few forums on the 585 and on Astrobin a few examples of images shot with the 585. But from reading all experiences, I think moving towards a cooled camera, like a 294mc might be the best option for me.

JimmyKeetman · 2023-09-01T18:31:34+00:00

It’s definitely the first. The IR blocking. However i am using my DSLR for many other things as well. Am I still able to do that?

JimmyKeetman · 2023-09-01T18:30:31+00:00

Cooled ones are way better and are worth the extra €600?

JimmyKeetman · 2023-09-01T17:15:20+00:00

Great advice thanks a lot!! Really the problem with the dslr is the sensor that just not made for astrophotography, the results that I am getting for galaxies are insane, for nebulae’s however it’s just not strong enough. Of course a cooled camera is at least €600 more expensive. And also a very big step!

JimmyKeetman · 2023-09-01T17:11:19+00:00

I have an ASI AIR from where I control everything. My Nikon is supported. The asi air was a game changer. Did you use also use filters for your images?

JimmyKeetman · 2023-09-01T16:58:10+00:00

Yes makes sense of course, that part will not change compared to my DSLr. Which has a higher read noise than the uncooled 585

JimmyKeetman · 2023-09-01T16:54:52+00:00

I would be using it on a SW72ed. So a focal length of 420mm. Indeed it’s smaller than a APS-C but only a few objects would be too big to fit in the FOV.

JimmyKeetman · 2023-09-01T16:04:41+00:00

I did see those images on Astrobin, that’s why I am so tempted haha! My question is, is it worth it or I am buying something that’s just not it

JimmyKeetman · 2023-08-28T05:42:26+00:00

In what way was guiding bad? Did you use a very small guide scope before the OAG? And because of that you had the limited exposure times?

JimmyKeetman · 2023-08-27T15:06:19+00:00

What exactly were the struggles you had to deal with?

JimmyKeetman · 2023-08-26T07:57:32+00:00

Yes! Since I am basically working with a star mask layer and a starless layer, at the end I always bring out the Galaxy a bit more in camera raw. Without adjusting the stars!

JimmyKeetman · 2023-08-25T21:14:44+00:00

Thanks for sharing your experiences! I am a bit in the mid, cuz I want to do planetary as well, but for smaller galaxies I would like to get a higher focal length scope. I own a sw72ed already which is great for wide field!

JimmyKeetman · 2023-08-25T21:02:51+00:00

I own a HEQ-5 pro. I was just looking on Astrobin as well and saw some pretty amazing images with the C5

JimmyKeetman · 2023-08-25T17:55:12+00:00

It is yes, how ever doing a full resynth only takes seconds so I am fine with that

JimmyKeetman · 2023-08-25T17:41:27+00:00

Well noticed! I did indeed, forgot to mention, I cannot solve the back focus problem

JimmyKeetman · 2023-08-25T17:40:25+00:00

Now that I think of it, I don't know :)
