Skywatcher EQM 35 Pro Skyscan Goto Mount

I thought the Skywatcher EQM35 Skyscan Goto Mount would be an ideal entry into nightsky imaging following the little that I have managed to get done with the Star Adventurer after 3 years of owning it. This larger mount would drag my reluctant sorry little ass into astrophotography slowly but surely.

EQM 35 will allow simple star tracking and nightsky photography with current DSLRs that I own with the added ease of Skyscan and Goto capabilities. And when I am done and ready with that it will also allow for more serious astrophotography with flatfield apochromatic ed triplet proper telescope attached to a DSLR for more dedicated astro imaging. That's the plan trajectory anyways, has been for the past 6-8 years.

After Star Adventurer, this heftier unit should be able to handle the use of the Sigma 300/2.8 and the EF400/4.0. The EF400/4.0 was originally purchased when it came out with the intention of picking up Orion's Nebula but was never actually tested on the Adventurer after some weight considerations. The EQM35 which is heftier is rated to be able to carry up to 10kg load so it might just be possible.

The business end of star tracking.


The foldable travel tripod for the EQM35 mount, nifty folded size for travel when the need arises.

The above set up should be able to cover Milkyway widefield as well as deeper targets. With the Adventurer it may be slightly risky to use the long heavier SLR lenses and DSLR due to weight considerations, I'm sure how the motors would behave with larger load.

The following is possibly the route that will be taken for astro imaging if all goes well and according to plan:

Skywatcher Esprit 100ED Super APO Triplet Refractor (includes 3" focuser, 2" diagonal and finder scope with right angle viewer).

Field flattener

Adapter from field flattener to Canon EOS mount.

Canon EOS77 Astro APC camera wo IR cut Filter, 24 MP, Digic 7


And these hopefully will be able to target these as part of the earning curve to master going futher into astro imaging :


Andromeda

Orion's Nebula

Pleiades

Considering that they are only 7 days of clear sky in total with a dark night here in Norway, it'll be a while yet before these objects get their due coverage. Maybe the sun could also be a viable target, in that case a 150mm sun filter would be required. For  both the Sun and the Moon, a 2x Barlow might be useful to achieve 1100mm.
