For imagers who know what they want

Advanced imaging packages

Complete systems, specified the way we would buy them ourselves - mount, optics, rings and back focus all worked out on paper. Pick mono or colour on any card and the rest of the build follows. Every part is listed with its own price and links to its own page, so nothing here is a black box.

How we choose the parts

Three rules we don't break

Every package here is specified the same way, and none of it is guesswork. If you already know all this, skip to the kits.

One

Mount class before optics

We size the mount to about 60% of its rated payload with everything attached — camera, filter wheel, guider, cables and dew straps, not just the tube. A strainwave mount at 80% of rating will track, but it will not settle after a nudge, and at long focal length that shows in every frame.

Two

Focal length decides the guiding

Under about 600 mm a guide scope is fine. Past 800 mm, differential flexure between two tubes becomes the limiting error and an off-axis guider is the honest answer — it takes its star through the main optic, so there is nothing to flex. Every kit past that mark defaults to the OAG, and a camera with its own guide sensor sidesteps the question entirely.

Three

Filter size follows the sensor

An APS-C mono sensor takes 36 mm filters; a full-frame sensor measures 43.3 mm corner to corner and needs 2-inch glass or the corners vignette. The ZWO EFW Next Gen covers both, and the card picks the right size of it off the camera you choose — you cannot end up with a 36 mm wheel and 2-inch filters.

A fourth thing, less a rule than a fact people are caught out by: a Takahashi optical tube ships on its own. No rings, no dovetail. Every Takahashi kit below lists the correct rings or tube holder for that exact tube diameter, ticked by default — untick it only if you already own a set that fits.

The one real decision

Mono or one-shot colour

Every package below opens with this switch, because it is the choice that changes everything downstream - the camera, whether you need a wheel and filters, what size those filters are, and how many nights a target takes. Here is the honest comparison.

One-shot colourMono + filters
How it worksA colour filter array is bonded to the sensor. Every sub is already a colour image.A bare sensor behind a wheel. You shoot each channel separately and combine them afterwards.
ResolutionEvery pixel guesses two of its three colours from its neighbours.Every pixel is measured, in every channel. Visibly sharper on small targets.
A night's workPoint, shoot, stack. One session can be a finished image.Three or four times the exposure for the same target, usually across several nights.
Bright skiesA dual-band filter in a drawer ahead of the camera does most of the work, and every APS-C colour configuration below offers one. The colour array still limits how narrow you can usefully go.Where mono wins outright. 4.5 nm or 3 nm passbands cut city light almost entirely.
Filter sizeOne 2-inch filter in a drawer, not a set. A full-frame colour sensor is the exception - the drawer aperture clips its corners, so we leave the option off those cards.APS-C takes 36 mm; full frame takes 2 inch. The card sets this from the camera, not from you.

Our default for mono is Antlia throughout — the LRGB-V Pro set for broadband and the 4.5 nm EDGE set for narrowband. Antlia holds tighter band edges and better-matched channel exposures than the cheaper options, which is time you get back in processing rather than money you spend twice. Every kit lets you swap either set, and the difference against the included pair shows on the card before you add anything to the cart.

If you are shooting colour from a suburban backyard, the equivalent move is a dual-band filter. Pick an APS-C colour camera on any kit below and the option appears: the L-Extreme for the heaviest skies, the L-Quad where you want stars and galaxies to stay honest, both riding in a ZWO drawer so you can pull the filter out for broadband targets without touching back focus. We do not offer it on the full-frame ASI6200MC — a 2-inch filter in an M42 drawer does not clear a 43.3 mm sensor cleanly, and vignetted corners are not a trade worth making. Call us if you want that combination and we will spec a larger drawer.

One thing that surprises people: below about f/4 a very narrow filter starts to lose transmission, because the light cone hits the coating at a steeper angle. If you are running the Epsilon 180ED at f/2.8, ask us before you upgrade to 3 nm — the 4.5 nm set may well outperform it on that telescope.

Complete systems

Seven systems, small to large

Ordered by aperture. Switch any card between one-shot colour and mono - the camera list, the wheel and the filter sets all follow, and the filter size is read off the sensor so it can never disagree with the wheel. Mono includes the Antlia LRGB-V Pro and 4.5nm EDGE sets; APS-C colour can add a dual-band filter and the drawer that holds it. Swap anything and the difference shows before you add to the cart. Prices in Canadian dollars.

The portable one you never outgrow

Takahashi FSQ-85EDX on a ZWO AM5N

85 mm f/5.3455 mm with flattenerPetzval quadruplet44 mm image circle

The BabyQ is the telescope people keep after they have sold everything else. A four-element Petzval with the 1.01x flattener already fitted, flat to the corners of a full-frame sensor, on a harmonic mount light enough to carry to a dark site in one trip.

What it's great at

Flat, colour-perfect fields with nothing to space and nothing to tune. At 455 mm it is forgiving of guiding error, so nights are productive rather than fussy.

The trade-off

85 mm gathers what 85 mm gathers - small galaxies stay small. You are paying for optical perfection across a wide field, not for reach.

Back focusWith the bundled 1.01x flattener the FSQ-85EDX runs 455 mm at f/5.4 and wants 56.2 mm of back focus. The CA35 ring in this kit is the M55.9 drawtube adapter Takahashi lists for this telescope. Tell us the camera and filter wheel you plan to run and we will work the spacer stack out on paper and quote it with the kit, before you order.

Sky-Watcher Esprit 100ED on a Wave 150i Pro kit

100 mm f/5.5550 mmTriplet apoFlattener and rings included

A proven 100 mm triplet on Sky-Watcher's 15 kg strainwave mount, bought as the Wave 150i Pro kit - head, carbon-fibre tripod and extension tube in one part number rather than three, with the extension already there so the tube clears the legs on a meridian flip. The whole thing packs into a car without a second trip.

What it's great at

Triplet colour correction and a matched flattener at a sensible price, on a mount and carbon tripod combination that is genuinely light for what it carries - and it arrives complete rather than as a shopping list. The Esprit ships with its own rings and dovetail, so there is nothing extra to buy to get it on the mount.

The trade-off

550 mm is a wide-field focal length - excellent for nebulae, modest for galaxies. If galaxies are the point, look at the TSA-120 or TOA-130 below.

Back focusThe Esprit's own field flattener sets 55 mm of back focus - the industry standard figure that every camera, filter wheel and off-axis guider here is designed around, so the train adds up without custom parts.

Sky-Watcher Esprit 120ED on a Wave 150i Pro kit

120 mm f/7840 mmTriplet apoCounterweight included

The same Wave 150i Pro kit as the Esprit 100 package - head, carbon-fibre tripod and extension tube together - with a counterweight added. At 120 mm the tube is long enough that balancing it properly matters, and the strainwave mount tracks better when it is not fighting an offset load.

What it's great at

840 mm puts galaxies and the smaller nebulae at a sensible scale, and the triplet holds colour correction right across it. Rings and dovetail come with the telescope, and the mount kit arrives complete. Still a rig you can carry outside in two trips.

The trade-off

Past 800 mm the guiding has to be right. We default this kit to an off-axis guider rather than a guide scope, and you should expect to spend a few sessions dialling in polar alignment.

Back focus55 mm from the Esprit flattener, same as the 100ED. With an off-axis guider and a filter wheel in the train that 55 mm fills up quickly - send us your camera model and we will lay the train out on paper before you order.

Visual and imaging, no compromise

Takahashi TSA-120 on a ZWO AM7

120 mm f/7.5900 mmTriplet apoTOA-35FL flattener included

The TSA-120 is the telescope that does both properly - a triplet apo that photographs beautifully and is also one of the finest visual refractors made. This kit lists the TOA-35FL flattener, the 2 inch to M48 camera adapter and the 125 mm tube holder alongside the tube, so there is nothing else to order before you can image with it.

What it's great at

Genuinely dual-purpose. Planetary detail and double stars at the eyepiece, then the flattener and a camera for deep sky at 900 mm. Takahashi mechanics that will outlive you.

The trade-off

At f/7.5 it is slower than the astrographs here, so expect more total exposure. And the TOA-35FL corrects 40 mm, which rules out a full-frame sensor on this kit - mono or colour.

Back focusThe TOA-35FL holds 117.5 mm of back focus and corrects a 40 mm image circle - APS-C and smaller. That is why there is no full-frame option here: a 43.3 mm diagonal sensor would sit outside the corrected field. Every camera on this card is APS-C, so the filters are 36 mm throughout. The flattener presents a 2 inch female output, so the kit includes the 2 inch to M48 adapter that picks up a ZWO camera or filter wheel. Send us the rest of your train and we will work the remaining millimetres out with you before you order.

Takahashi TOA-130NS on a CQ350 Pro

130 mm f/7.7990 mm with flattenerOrtho-apo triplet60 mm image circle

The TOA is Takahashi's orthogonal apochromat - a triplet designed to remove the residual colour error that even good apos leave behind. This kit pairs it with the TOA-645 large-format flattener, the wide-mount camera ring and the 156WM double-ring holder, on the CQ350 Pro with its heavy-duty field tripod.

What it's great at

About as good as refractor optics get at this aperture, and the TOA-645 corrects a 60 mm circle - comfortably past full frame, so nothing you put behind it is wasted. The switch starts on mono here because that is what this telescope is for.

The trade-off

Heavy, expensive, and slow at f/7.6 - this is a system for people who care more about how the stars look than how many hours it takes.

Back focusThe TOA-645 flattener holds 990 mm at f/7.6 and corrects a 60 mm image circle, and threads M72 x 1 on both faces. The wide-mount ring in this kit screws straight into that M72 output and presents M54 x 0.75 to your filter wheel or camera, with a published 28 mm light path. Send us your camera and we will check the full train adds up before you order.

The fast one

Takahashi Epsilon 180ED on a CQ350 Pro

180 mm f/2.8500 mmHyperbolic astrograph44 mm flat field

An f/2.8 hyperbolic astrograph with 180 mm of aperture. It gathers roughly four and a half times the light of an 85 mm at nearly twice the speed, which means faint outer nebulosity appears in an evening rather than over a fortnight. On the CQ350 Pro, which has the payload to hold a short heavy tube steady.

What it's great at

Speed. Nothing else here comes close - an hour on this telescope goes further than a night on an f/7 refractor, and the field stays flat across a full-frame sensor with no separate corrector to buy.

The trade-off

Fast optics are unforgiving. Collimation matters, tilt matters, and back focus has to be right to the millimetre. At f/2.8 a 3 nm filter also starts losing transmission - ask us before you upgrade the narrowband set on this one.

Back focusThe Epsilon corrects inside the tube - the hyperbolic primary, flat secondary and integrated flattener put a flat 44 mm circle 56.2 mm behind the focuser, with no corrector to buy or align. With a filter wheel in the train 56.2 mm is tight, so tell us your camera and wheel and we will confirm the spacing and the output thread with you before you order.

Askar 185APO on a CQ350 Pro

185 mm f/71295 mmTriplet apoObservatory class

185 mm of triplet apochromat at 1295 mm, on Sky-Watcher's CQ350 Pro with the heavy-duty field tripod. This is the largest refractor package on this page that still comes apart and travels - beyond this you are into permanent piers.

What it's great at

Aperture and focal length together. Small galaxies resolve into structure, globulars resolve to the core, and the triplet holds colour across it all. The switch starts on mono because at this scale that is what the aperture is for.

The trade-off

This is a two-person setup and a serious commitment. At 1295 mm you need excellent seeing to use what the optics can deliver, and a dark site to justify the aperture.

Back focusThe 185APO has a retractable rear lens tube and takes Askar's own flattener and reducer options - which one is right depends on the sensor you choose. Tell us the camera and we will quote the corrector and spacers with the kit rather than guess here.

Nothing here quite right

We spec one-off systems every week

These are the combinations we are asked for most often, not a fixed catalogue. Tell us what you are trying to photograph and where from, and we will spec it properly - including telling you when a cheaper system would do the same job.

  • Your targets, and whether you image from home or travel
  • Pier, tripod or permanent observatory
  • Mono with filters, or one-shot colour
  • Whether it needs to run unattended

Worth adding

The parts that finish a system

None of these are in the kits above by default, and all of them get asked about. Dew heaters are sized to the outside of the tube, not the aperture.

Takahashi tubes ship without rings. Every holder is cut to one tube diameter, so tell us the exact model and we will match it - this 125S fits the TSA-120 and FSQ-106ED.
