sky watcher 80mm f5

[Erwin Kats]

yesterday received my package from telescope-service.de

fast and great shipping of TS.

i ordered the 80mm f5 in stead of my 80mm f11, the length of the 80mm f11 was just to much, and the focal length to long, finding stars in the field with my guider camera ( qhy 5 ) was getting hard.

so, last night i went outside quickly to perform some testing because i will use this setup soon in south france again.

here some shots.

like my other 80mm f11 from orion, the dew shield is falling off everytime.

the orion red dot finder does not fit, it seems there is a difference between the orion and skywatcher dovetail :|

i had this problem also with attaching the RDF on my vixen r200ss

some more.

and i also ordered a micro focuser from TS for lenses.

and at last an image of 8x20 minuts with qsi 583 ws and baader 7nm Ha filter chip cooled down to -30 celsius

flaming star nebula ic 405, ic 410 m36 m38 and some more object in the FOV

some vignetting in the field due the usage of 70-200 2.8 is on 100mm f2.8

here i made the RDF fit the scopes finder holder.

a 10 second exposure through the scope with a SX lodestar

I haven't had a chance to try my ST80 as a guidescope yet .. clear but blowing a gale tonight...

I had exactly the same problem with the dewshield falling off all the time but a piece of sellotape round the plastic part before refitting the shield cured that...

That reminds me...

I still havent got round to finishing my DIY vesrion of the TS micro focuser...

Have fun in France...

These must be just about the most common guidescopes in the country!

Good luck and clear skies

thanks billy, i am back in the mean while, weather was not good

only had time to take 1 hour of Ha on californie nebula in widefield.

i was going there to collect LRGB data but not succeeded.

( already booked 10 days in the hope for some better weather )

Stuart, its small, it works, its cheap, its just great

for guiding within maxim and PHD you have to do some settings ( the star has to move more pixels then with the stock settings )

this due the smaller focal length.

here a screenshot from maxim dl 5 pro guiding.

RMS is in pixels.
