Dobsonians for first users.

Had a terrible night observing, well before moon rise, Jupiter was ok apart from heat haze.
Even with 25 mm (with the later problem)
Went looking for DSOs near the large mallengenic cloud but for some reason the 25mm now makes all stars appear to be like saturn or small galaxies?
I don't think it is collimation, as if I rotate the EP the saturn/galaxy beams turn with it?
I did notice the outside of scope had quite a bit of dew, after an hour of observing.
The 10mm was ok but too limiting for wide FOV.
Does the 25mm need cleaning? How do I fix this?
What is going on?

If there is dew around the first thing that fogs up on my dob is the secondary mirror, a quick blast with a hair dryer sorts that out.

Probably had dew on the EP. A gentle twirl with a cotton bud inside and out will remove it. If dewed up EPs become a recurrent problem for you,
you can get an EP dew heater that wraps round the EP. You can also get primary and secondary mirror dew heaters.

Thanks raymo, will try that, I better get some solar panels to run alll these extra gadgets I need, hair dryers ,due heaters and fans for mossies
Feel like I am setting up a film studio, all I need now is the mothership to do a roll over the valley mountains and capture it with a web cam attached.
Might be cheaper to build a mudbrick observatory with bamboo dome......?

Is the sun out at night where you live then Pete?

No, I plan to create a cylindrical light gathering panel to harness distant suns, it will be 4 feet wide.
Which will solve solar energy during the night.
At least enough to trickle charge a small red led.
With a mirror and lenses it will be a dual purpose telescope.

Sounds like a great invention, perhaps you could market them.
