16" Dream Astrograph - filtered tube offering (16DAtube)

Obviously the first and foremost priority for a forced air system is to help the mirrors reach and follow ambient temperatures. In doing so we achieve the benefits previously mentioned.


The other benefit is that we are filling the telescope chamber with filtered clean air. This helps keep the optics cleaner for a much longer length of time. For remote imagers/science, we advise our clients to leave the fans on all the time, even during the day. These fans are very light and efficient, using less than 10 watts altogether.

This product now comes standard with a 5.75" cellular secondary mirror that weighs only 1.5 lbs., compared to a 5.5" monolithic secondary that weighs 3.7 lbs.


 

Dream currently has 3" coma correctors in stock. A large batch of primary mirrors for the 16" Dream Astrograph line has been started. We expect to receive the first completed primary mirror around the first week of September.

We have already taken the first orders for the tube version of the 16" Dream Astrograph. We are proud that it will be the second Dream Astrograph at SRO.

Another feature exclusive to Dream are the two Viewports on either side of the focuser. Again, a disadvantage of a solid tube is that it obscures your view of the secondary mirror's face. We need to see that face when using a template on top of the secondary. Such templates help to physically locate the mirror (while using a laser or crosshair accessory in the focuser) for its given offset. That is why Dream has designed in these two 0.5" ID Viewports on either side. At night you can sight through one Viewport while shining a light in through the other. They are angled to point directly to the offset center of the secondary mirror. Having two also helps reduce the chances of the ports being inaccessible because of the telescope's angle/location.
