I had chance to observe Jupiter last night & tonight through Mum/Dad's open bedroom Window without the annoyance of the SynScan for now & annoying pole star setups, I just wanted to get down quick & dirty around 8:00p.m. pefect hits Due South West. There is lamp at the bottom of our garden which is in the passage way which passes round the back of our houses (light pollution)! I wish I could ask the council to switch it off but not sure whether family or resulting nearby neighbours would be happy about that when driving their cars round the back at night! If you could read my experience & then give me some tips as what to do to get better views, brighter views, more contrast, more detail & more colour with this scope & can you tell me whether I need a better 90' diagnal, better ep, better barlow lenses, better tripod & mount for manual observing & slewing which bring out all these things more than my standard ones.
How I faired? Performance issues/Instability!
I was able to move the telescope up & down freely okay manually no problems to get object in field of view. But not side to side left & right! a Nightmare! When you hold the diagnal mirror or EP to look through it the slightest movement from holding them or the telescope results in moving the telescope resulting in object dissapearing from the field of view. The scope moves too easily a few degrees left & right, then when I just get it into field of view & try to focus with the focuser wheels, that also moves object out of field of view, because the telescope has moved left or right also maybe because I have nudged it up & down in alt a bit aswell, you have to be rock stead I have come to realize it's actually impossible to be this steady without causing movement. I have a feeling it should be tougher to move telescope or the dovetail mount itself which is moving left to right easily with more tension so you can't knock it & move object out of field of view. The telescope shouldn't move like it does especailly when it's not supposed to moved left or right manually, should be stiffer if it runs on a stepper motor & is made for electronic control. I probably need a good manual slewing tripod to fix this scope to for manual viewings. It's just too tricky & feels unstable moving so easily!
This is bad especially when manual viewing, to keep tracking the object - Jupiter I have to moved the tripod I know this is the only way unless I purchase a decent manual tripod which keeps my scope steady & allows me to slew it without telescope moving left or right up or down easily! I took ages half the time trying to find the ojbect everytime I lost it! The losing the object wasn't due to the object moving constantly either as I kept correcting it & moving the telescope tripod legs so it pointed to the object again every few mins or so. Jupiter looked like a greyed pencil lead drawing, just not bright & grey gas swirling gases round ball their was no colour. I used the 20mm EP, then the 10mm EP. Then I used the x2 barlow with 20mm then 10mm. The picture looked the same except that eah was either farther away or closer & bigger. Jupiter looked big but there was no detail to be seen as it was just a grey looking ball & I could see swirling motions. Is there anyway I can see Jupiter bright, closeup & in detail with all the colour like when you see hubble. I know hubble is massive & in space & produces jupiter as you know it & see it. It's just not what I though. Maybe I don't have a telescope expensive enough to see jupiter likeI want to.
So is there anything I could do to improve the contrast, colour, brightness & detail so I can see the different colours on jupiter & make out the different gasses & red spot. I with mine I can't make out anything, it's all grey as I'ved said loads of times. Do I need a more powerful telescope refractor or more expensive better EP's? On Mon night I saw the moon very well through my front bedroom window when moon was in the east. It looked ver good with my EP's & certainly was bright as I expected it & their was detail considering I was viewing through a Window. Jupiter wasn't so exciting! Overall I have enjoyed getting to know how to work my telescope & put it together for manual use at best, incl familiarizing myself with how to tighten & untighten diagnal mirror, insert barlow & EP. I a dab hand now with that. Also I might of messed up the red dot a bit it now doesn't meet the ojbect in the viewfinder. It probably needs fine tuning again & setting up. This happened because the telescope wasn't steady & was moving side to side when I start focussing, the movement of focussing moves the telescope & moves the object out of the field of view so I started messing with red dot & now that's messed up a bit.
