Advice on an upgrade path

Hi all.

I’ve been performing a lot of research due to the unforgiving cloudy weather and am looking for advice.

To state my current gear:

A canon R7
Sigma 100-400mm f5/6.3
Startracker Adventurer GTI
Remote shutter cable

📷 1O8lzzm.jpg1O8lzzm.jpgNow I’ve thought about a lot of options, including

A redcat 51/61 - these looks like it will suit my mount in terms of weight, and they offer nice mounting offers for guiding scopes
A guiding scope - My sigma is “semi slow” and I think a guiding scope will help remove that as a limitation
A faster lens - Rokinon 135mm is on my radar.
As much as i’d enjoy a dedicated astro camera, for now I think i’m happy with the canon, until summer, i’m going to presume to myself.

I’ve also looked into the ASIAir but i think i’d need a way to figure out mounting it nicely, to which other telescopes may already help with that.

Was hoping the experienced users here could help chime in and give me some ideas.

Thank you so much!

I think the really weak point in your rig right now is the tripod. You might think about the tripod and pier extension that’s available for the GTI mount.

May I ask why the tripod?

Tony Gondola avatar

I’m surprised you would ask this if you’re using the rig as is. I think you need a solid base before doing much else. If you stay with what you have it will fight you every step of the way.

I decided very early on that Astrophotography was going to need me to get the right lens (a telescope), and the right camera (an Astro camera) Or else I would quickly kill my DSLR. My Tamron 150-600mm wasn’t the right lens for deep space.

DSLR’s are designed for terrestrial pictures. They don’t normally have sensor cooling. And they tend to have finite shutter operations. Mine was at 86,xxx when I got interested in this. 150,000 was the twilight window.

Astro Cameras are designed for astro imaging.

I think Tony is pointing out you need a real mount. But I can’t tell what you do have there. But it does not appear to be a mount.

Sorry I’m really not following what is wrong with the tripod. It’s a Benro Mach3, suitable for 20kg and when extended is almost taller than I am (190cm)

What do you recommend as a solid base?

Yeah that makes sense regarding DSLRs, shutter count is indeed in the back of my mind.

I’m fully portable as I cannot image at home, so it’s more gear to lug long to a remote shooting location as it needs to be powered. I think it’s going to be something to sort out sooner rather than later though.

It’s the star adventurer GTI, i’m not sure how this is not a mount

A tripod that might be suitable for terrestrial photography won’t give you the needed stability for astrophotography. You are entering another world of precision here so you need to start wrapping your head around that. What I’m talking about is this: https://www.skywatcherusa.com/products/star-adventurer-tripod

You’ll also find the extension useful because if you go to longer a OTA it will prevent the tripod legs from interfering as much. https://www.skywatcherusa.com/products/star-adventurer-tripod-extension

For stability you need mass as much as you need strength.

Always start with the mount! As you progress through your “arc” of this hobby, most of us have used various OTA’s (The telescope) during our journey as you most likely will. The AM5’s are popular, I prefer the traditional German design. A good mount will help and really is the best place to start with a rig upgrade. After that move to a dedicated astro camera then upgrade the OTA/lens last… The best camera on the best telescope using the best software on an undersized mounting will never give you the results you seek. While a good camera on a respectable telescope with a proper mounting will deliver…

That is OK, for terrestrial photography, but a photography tripod is not a solid base as it can vibrate. OK, you hang a few kg of weights on the tripod and so it becomes less prone to vibration but that would have to be deducted from carrying weight.

Another disadvantage of photography tripos is that they easily rotate on the top. Yes the feet are stable but the construction let it rotate on the top.

Below you can see a solid base with each pier weighing 7 tons. I know I know, I am joking…

Hi, Jack.

I’ve only been at this for 4-5 years and really still learn most of what I need from forums such as this one, astronomy club members, and YouTube gurus (see some suggestions below), all of which have been invaluable. So a couple of personal experiences and what I learnt early on and since may help since I was where you are not that long ago. One word of warning…once you get going, you will find it an expensive habit (or addiction).

1) Mount: The mention of tripod and mount as being the most crucial components are excellent advice - this is repeated by many people beyond this forum. I started solid (EQ6R Pro) and never had a complaint - rock solid. That said, the EQ6 mount is very heavy (to carry, to set up and transport) and I now have an AM5N as well. I bought the matching TC40 tripod with the AM5N and although it is designed for it, the tripod still flexes enough to make long exposures (2-5minutes) frustrating, even with weights added for stability. So I now put the AM5N on the EQ6 tripod for deep space, and on the TC40 tripod for solar (because exposures are in milliseconds and it’s easy to throw in the car). Bottom line - spend your money on a good mount and tripod once. If you are sticking with the SkyTracker, then take Tony’s recommendation and get a rock solid tripod but once you really get into astrophotography, you will face the inevitable desire to get a better mount and tripod that can support heavier gear and track accurately for longer exposures. Spend once and spend wisely (or as some say, “buy once, cry once”).

2) Camera: I started with a Canon RP DSLR (albeit without a decent mount), got the bug and realised I wanted to go for a complete astro setup (thus the EQ6 mount mentioned above). I used my DSLR on my first scope, but leaving aside the choice of scope (see below), a dedicated astrophotography camera quickly becomes the next thing to consider. Then decide if you want to shoot RGB or Narrowband (NB). If you only do RGB, then a colour camera is fine, but you will find that you probably need skies without much light pollution for most things you will want to shoot. In order to provide the maximum choice, with no expectation of ever needing to upgrade, I went for a mono astro camera and a filter wheel which could hold all the LRGB and NB filters. To shoot nebulae for example, I shoot NB for the nebula gases and RGB for the stars and process them separately (that’s a whole other topic). A good astro camera is required for decent long exposure images. Note also that with mono, you get 4x resolution, since each pixel is its own mono point, whereas RGB uses 4 pixels for each point. That said, plenty of people do stunning work with a DSLR on a good tracking mount. So once again, the mount is key.

3) Scope: I never understood people asking me what sort of astro I wanted to do before providing suggestions on scopes. I thought astro was astro. But of course the requirements are different for Lunar, Planets, Solar, and Deep Sky (DSO), which can be further divided into Galaxies and Nebula. For example you need a shorter focal length for nebulae (generally) and longer for galaxies. I’ve ended up with a couple of scopes that suit different purposes. Decide what you want to image (at least initially) and find a scope that matches that need. There are so many scopes and levels of image quality they offer. Once bitten by the astro bug, you’ll likely have more than once scope.

4) Beyond: Other considerations will emerge, such as software to run the gear (I started with APT and settled on NINA), guiding (separate scope or OAG), power supply for traveling into the bush, image processing software etc. As I said, an expensive addiction, but a good one.

Some good YouTubers that have great advice on gear and on astro more broadly:

I hope that helps a bit, Jack. Do lots of research (which you are clearly doing by posting on this forum). There is so much to learn and so many mistakes (aka learning opportunities) to be had along the way. Have fun!

Cheers.

Paul

Jack, Here are my recommendations.

1) Go to the Astrobin equipment mount section for the Star Adventurer GTI and see what other people’s results are and what they are using with it. You can get a lot more out of your modest tracker mount.

2) Watch Nico Carvers UTube Video on the Star Adventurer GTI and compatible scopes. https://www.youtube.com/watch?v=2rX1Fs12smY

3) If you must shoot with a camera lens shoot wide open to avoid crazy star spikes. Even an inexpensive refractor will beat most camera lenses.

4) More integration time. Short subs if needed due to lack of tracking accuracy with the GTI, but more total integration time.

5) Upgrade to a dedicated cooled astro camera. Will greatly improve noise issues.

6) Learn to guide.

7) Make sure your tripod is truly stable. Doesn’t cost much to upgrade the tripod compared to the benefits.

CS, Bob

Thanks everyone for your detailed insights. Truthfully I’m really surprised regarding the tripod as I’ve used it a few times now and it seems stable.

I bought this tripod from a camera store after seeking recommendations for one with the intent of putting a star tracker on it. They recommended this one which is what I have: https://www.amazon.nl/-/en/Benro-Mach3-Aluminum-Tripod-TMA47AXL/dp/B00YEU9EM2

I’d like to really understand what the main difference is between the one I have and something like https://www.skywatcherusa.com/products/star-adventurer-tripod

I’m assuming the star adventurer tripod will handle vibrations from the star trackers movement better?

If this is the case then I think i’ll need to sell and swap

Just to quickly reply to a few people here:

Bob:
Amazing list, thank you. I’ve actually watched that video as part of my research, very useful.

Paul:
Very informative and I appreciate the time taken to write out a big reply with your personal journey.

Rainer:
Noted, although I think installing concrete pillars is a bit beyond my reach right now :)

Many thanks

Your tripod is fine for what it is supposed to do, carry a GTi, rest assured and ignore the naysayers. I have one even lighter than that and it good for lightweight scopes like the smaller refractors (let's say up to 4", short tube) and fast heavy lens. Your camera is likewise perfectly fine for deep sky photography, within the limitations of Canons or DSLR in general and I shan't worry one tiny bit about shutter count (of which I lost count on my many cameras). If fact I am positive that colour rendering in DSLRs is way better than whatever the astro-cameras deliver. Given your predicament I think a fast wide lens such a Rokinon would do fine and even better a 300mm f/4 such as the Canon EF 300mm f4 L IS USM. As for controller I strongly suggest you avoid ZWOs and instead go with either StellarMate or a mini PC with NINA.

OK, sorry, but I was looking at the picture and could not make out the mount. I went surfing and found it.

It is a mount. Bravo. And you should be able to use it for AP with a bit of practice. I managed to use my AVX for a while. I think what many are alluding to is better mounts work betterer. Just like AP cameras will work better for AP.

Lucky for many, there are several alternative’s now. Like the Harmonic drive mounts. They were with their learning curves, but I’m seeing more and more impressive images with them now. When I was beginning around 2013, there was expensive, and terribly expensive GEM mounts. Like your GTI, I jumped in with my AVX. My learning curve was not only rocky, I had many boulders rolling down at me. If I hadn’t been so determined I should have given up. When my AVX died for its third and last time in 3.5 years, I finally made my leap to my present mount. Not shall I ever want again.

But I didn’t give up. And as I corrected my mistakes, I made much better choices in leaps and bounds. My first Astronomy camera choices were shit. My latest camera suits me fine. An ASI 2600MC Pro. Kind of the DSLR of color astro cameras, IMHO. APS-C sized sensor and gives me great images as a rule. I use 2 different Light Pollution filters with it and get point-and-shoot images that are web ready after stacking and saved as a jpg. I mostly make web ready You Tube slide shows with them. Simple and real easy. I did the filter route for many years, and the mono camera. But going back to my old ways of a color camera is a joyous method. The Astro cameras have come of age if you choose the right ones.

But it took a lot of struggles to get where I am. And a lot of money in the long run. My mount is my “forever mount”. Not a lightweight by any means but stable as a rock in use. The intent is to help you avoid the mistake others of us made on our way.

At this point the only thing that gives me any grief at all is the occasional software glitches. And making sure I get all my ducks in a row when recovering from those software fiascoes that crop up in AP.

You can continue with the GTI, but if you ever go to a premium mount, you will be glad for the things they will eliminate.

If a large part of your concern is unforgiving cloudy weather then I would suggest looking into a remote observatory like Starfront. Send them a Seestar (S30 or S50) and pretty soon you will have so many amazing images it will change your life.

Hello Jack. I have the RedCat 51 (consider the 60mm if your budget allows it) on the SA GTi, with a small 30mm guide scope and a mono guide camera (the ASI 120MM or similar will be just fine). As others already pointed out, get a better tripod. The mount is perfectly fine for a small rig, but consider a sturdier tripod. I use an old Celestron steel tripod that used to hold my ASGT, and it is rock solid. If you can stretch your budget even further, get an autofocuser and a mini PC. I hope this helps.
