Losmandy D Series Universal Dovetail Plate 19"

Product Overview

The DUP19 is Losmandy's 19-inch universal D-series dovetail plate. It carries six sets of mounting holes — 3.5", 60 mm, 2", 1.5", 35 mm and 1.25" separations — and Losmandy lists it as fitting the Meade 8, Celestron 8, Meade 7, Celestron 9.25, Meade 10, Celestron 11 and Meade 12. It can also serve as a side-by-side plate at a 14.875-inch separation. One safety stop screw is included.

Who It's For

This is the middle length, and it exists for the SCT and Maksutov crowd. The 3.5-inch separation that the 14-inch plate lacks is what lets it bolt directly to the rear cell holes of the larger Meade and Celestron tubes, and the extra length gives the fore-and-aft travel a heavy imaging train needs in the saddle. Its second use is as a side-by-side platform: two instruments at 14.875 inches apart on one plate.

Key Features & Design

• Six mounting hole separations: 3.5", 60 mm, 2", 1.5", 35 mm and 1.25".
• 19 inches long, for more balance travel than the 14" plate.
• Listed for the Meade 8, Celestron 8, Meade 7, Celestron 9.25, Meade 10, Celestron 11 and Meade 12.
• Doubles as a side-by-side plate at 14.875" separation.
• One safety stop screw included.
• D-series profile, accepted by every current Losmandy saddle.

Recommended Uses

Mounting an 8" to 12" SCT or Maksutov directly to its rear cell holes. Carrying a long refractor that needs more balance travel than a 14-inch plate allows. Side-by-side work, with two instruments 14.875 inches apart. Building an imaging platform where a guide scope and the main tube share one plate.

Compatibility and Accessory Notes

• Saddles: any Losmandy D-series saddle — the G-11 saddle, the GM8 saddle plate, and the twin saddles on the AZ8.
• Other lengths: the 14" plate for shorter tubes, the 24" for the longest.
• Purpose-made SCT plates: if you would rather have a plate cut for one tube, we stock the Celestron 8", Meade 8", Meade 7" Maksutov and Meade 14" plates.
• Dedicated side-by-side: the DVSBS is the purpose-built twin-saddle plate if side-by-side is the main job rather than an occasional one.
• Rings: the DVR108 guide scope rings mount onto the plate.

Good to Know Before You Order

• The 3.5" separation is the reason to choose this over the 14" plate if you are bolting to an SCT rear cell. Check your tube's hole spacing against the six separations before ordering and we will confirm it with you.
• Used as a side-by-side plate, the separation is fixed at 14.875". That suits a main tube and a modest second instrument; the DVSBS gives two full saddles at 10" centres instead.
• 19 inches is a long plate. On a shorter tube it will overhang, which costs nothing but looks and a little weight.
• Specifications are Losmandy's published figures.

Frequently Asked Questions

Is it difficult to set up?

No. It bolts to your tube's existing holes or to your rings, then slides into the saddle and clamps.

Which telescopes does it bolt straight onto?

Losmandy lists the Meade 8, Celestron 8, Meade 7, Celestron 9.25, Meade 10, Celestron 11 and Meade 12.

Can I really use it side by side?

Yes — Losmandy rates it for a 14.875" separation in that role. For heavier pairs the DVSBS is the stronger answer.

How is it different from the 14" plate?

Five extra inches of length and the additional 3.5" hole separation, which is what the larger SCT rear cells need.

Does it come with mounting screws?

One safety stop screw is included. For a tube-specific installation the purpose-made plates ship with their mounting screws as well.

Bottom Line

In short: Losmandy's 19-inch universal D-series plate, six hole separations including the 3.5" that SCT rear cells need, and a 14.875" side-by-side option — the length to choose for an 8" to 12" SCT or a long refractor.
