So, i have settled between 2 eyepieces for my scopes.
The explore scientific 6,5 mm 52degree
and the Skywatcher UWA Planetary 6mm
I have read that the explore scientific gives better contrast and views.
The explore scientific will give me 184x and barlowed 369x So should i trade less magnification for more detail?
I need my garage back so am selling my excess mounts.
1. EQ5 motorised on both axis.
No tripod this was mounted ony pier. Tracks well.
£100 Collect only because of weight .
2. An older type Skywatcher AZ goto mount that came with my SkyMax 127. Good condition .
£100 Collect please but might be able to send if you arrange courier.
SOLDto Pitbull ...thanks
3. AZ GTi goto in excellent condition . Still have the box so can send at cost.
The pic shows it with a telescope on it which is not included.
Location just north of Newark on A1
Thanks for looking
mods VB please move
I have been using my Skywatcher 8” Dobsonian for some time now, and decided I wanted a good refractor with an EQ mount as my next scope. I chose the Skywatcher Evostar Pro 80mm with an LX70 EQ5 mount. This seems to be a great scope to compliment my Dob, but I'm still getting used to the EQ mount! Found some good Youtube videos and am hoping for a clear night soon to really give it a workout! Any advice is appreciated!
I've realised that I'm not a fan of barlows, I'm also not loaded with cash. I love my two BST's 8mm and 25mm, I'm not so keen on my 15mm meade.
I've recently expanded my scope collection due to some inheritance with a 127 Mak, so my question is what would be a benefit to my eyepieces, replace the 15mm with a BST? Go lower than my 8mm? Go higher than 25mm? With BST's I would easily get two below £100 or go for something different and spend up to £100 on one eyepiece? Have a wide range of focal lengths and ratios over my three scopes, do I plan for different eyepieces per scope or stick to common eyepieces? Before anyone suggests Televues, I'll need to spend a fair bit on the wife before they turn up in the post? unless of course someone knows of deals going round
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?
