Thanks for looking
I have an EQ5 telescope mount which i use for astrophotography. I have modified it with a motorised RA axis using a bipolar stepper motor - my thread for the build is here .
I want to expand the mount's tracking ability by motorising the DEC axis and using a guide scope/camera. I generally use the mount in fairly remote locations so would like to use a raspberry Pi for portability.
I understand that I'll need to use a Raspberry Pi Camera Module for the guide camera.
The capability I want is:
1. guide the mount along RA and DEC axes using a guide star as feedback
2. track the mount using the RA axis only, and if possible continuously take 20-30 second exposures on the guide camera (this functionality is optional, but would assist in polar alignment of the mount)
I don't want any GOTO capability. I am very new to RPi and need some help:
- do I need to write code for this, or is there existing programming available for what I want to do?
- is it possible to avoid the use of screens (in the field)? My preferred option would be to flick a switch to start and stop the guiding, with another switch for alignment mode (or something simple like this).
- do I need to use any particular stepper motors/drivers for raspberry Pi? I'm using a bipolar stepper motor running quarter steps, with an A4988 stepper driver
- is the RPi 3 Model B+ the unit I should buy?
So guys after lots of advice reaserching and reading for the last 2 months i ve decided that i m going to either get a Skywatcher 200P(DOB) or a Skywatcher Heritage 130p(DOB)
If i get the Dobsonian i ll be using it about once or twice a week (if i have clear skies that is) i ll be taking a taxi to a semi dark sky location(atleast darker than my light polluted neighborhood) about 1.5 km away so the transportation cost will be close to nothing.I ve heard lots of great reviews about this neat 8" telescope and am tempted to buy it !(its going to be for visual i am aware of the earth's rotation)
On the other hand the Smaller more portable Version the Heritage 130p is a very neat telescope for its price(i ve heard) Its half the price of the 200p! I ll be taking this out almost every time i get out of the house(for walks or meetings with friends etc) I ve read part of the thread in cloudy nights and it seems like a great telescope! I ve even seen some very nice pictures with it (i know u need a mount). So what do you think guys? Should i go for the 200p or 130 p? I need the best value for money!
Hey guys it's me agaiinn. Recently I have been thinking about which telescope i should buy(its going to be my first telescope!!!!!) I have narrowed it down to 2 choices! The Skywatcher explorer 200p and the Skywatcher explorer 200pds
I just can't seem to chose oneee.
I want to do Astrophotography and i have heard that the Dual Speed focuser is going to help a lott. can someone please explain how? I m a total newbie and have just begun reading about Astrophotography.
On the other hand i ve heard that some eyepiece s will need an extension tube to help them achieve focus (due to the secondary mirror placed closer to the primary) and i really want to see through the telescope my self.I dont know if the extra 140€ that i have to pay to get the focuser and the pds and eq5 (rather than just getting the 200p and eq5 combined ) is worth it .Does it really make that big of a difference?? I hipe somebody can help me
I've decided the Skywatcher dual speed focuser is not up to astrophotography, there's too much play in it, I've tried tightening it up but it still flops about. My sweatheart has asked me what I want for my birthday/xmas presents, as the are very close together I don't mind just the one. So the question is which should I go for, either the Baader Diamond Steeltrack or the Moonlite CR2 dual speed crayford which with the installation kit will be quite a bit more in price.
