Hi All, wondered if you could help me make sense of this ... new HEQ5 - belt modded by FLO, all feels good, minuscule backlash but strange guiding.
Admittedly first time using it but baffled.
Failed calibration see image below and guiding seemed to be Ra and Dec following each other.
Stars look ok ish (@ 1500 mm )
Needle galaxy is poor as only about 10 mins each in RGB
note - it was hazy and did keep losing star in OAG
Thanks for looking
Dear Avalon Enthusiasts,
Do you have PHD2 Guiding Logs that you could share? Preferably at least 30 minutes long.
I am curious about the contribution to the overall error from the individual parts of the belt reduction gear. PHD2 Log Viewer provides nice analysis capabilities for that. I am especially interested in the frequency analysis.
Background is that I have built a motion module that uses a timing belt gear reduction quite similar to the Avalon mounts. Performance is quite good already, but I would like to compare it to the "real thing". 😃
I wonder if someone can please help, I'm fairly new to astrophotography and confused about aperture. Basically I'm looking at a Canon EF-S 55-250mm lens. It has the specs
f4-f5.6 does this mean that the lowest point of aperture possible is F5.6 or will it go lower. What I find confusing is that I have a lens that's the EF-S 18-55mm lens which has the specs of f/3.5/5.6 however My camera does allow me to set the aperture at f/8 The reason I ask cause it is advised to use a low aperture of f/8 to capture images of the moon.
Any help and guidance would be greatly appreciated!
Hi, my current telescope is Celestron ExploraScope 70AZ, thinking upgrade to skywatcher heritage 130P(came with 25mm ajd 10mm EP) , if i do, can i use the eyepiece (4mm) and x3 barlow from my old celestron on the 130P?
One more question, i ordered a eyepiece camera Svbony SV105, i wonder what is magnification of this camera and how it work to change magnification.
Recently i bought this brand new camera from David Hardie when he was doing a big sell out of some really nice items in excellent offers !!!
Unfortunately the camera although brand new doesn't serve my purposes so I decided to sell it at exactly the same price which I bought it from David , it was a really special offer 🤪
The camera new costs £1685 and I will sell it for £750 to be fair....🤪🤪🤪🤪
Camera comes with all its extras and case in absolutely brand new condition....!!!!
