Re: Excessive Star Glow
I don't know if this is possible with this kind of lens, but it looks like a back focus issue? The way you describe it, it looks like the lens is a bit too close to the camera sensor. Menno i not sure about that. As i said in my top post: The bahtinov pattern appeared spot-on. it can't be a focus i...

Re: Excessive Star Glow
thanks Tim The Tak 300 works manually with my Canon - and I have the Man/Auto switch set to "Man" so adjusting the Aperture settings does appear to work when attached to the Altair camera. My Altair 183c has a Built-in UV/IR filter - so would that mean that no additional filter req'd? From...

Excessive Star Glow
This is just a quick question on focusing. Equipment: Super Takumar 300mm, Altair 183c (Cooled) & Altair Hypercam Lens Adapter The Sharpcap captures are from upper-centre frame, 30-sec exposures. The bahtinov pattern appeared spot-on. However, all of the stars in the image have a bright centre a...

m42 > Altair 183c [cooled]
Hi
Just wondering if I can link my Takumar lens to the Altair 183c to capture in Sharpcap
♦ Altair 183c > Takumar SMC 300mm F/4 [M42]
1. Can it be done? what adapter is required?
2. What about backfocus?
thanks

Perseids Stacking?
Does anyone know of a simple method for stacking Meteor showers that were captured using a tracked mount?
I can't find a method for this for either DSS or Sequator
Is it possible, if so what would be the workflow?
thanks

Re: Hypercam 183c [fan cooled] cable query
Hi Robin thanks for the reply. putting the PC outside is not going to be practical. The active 10m cable has been used with the Zwo and SVBony the mini-PC located in our garage to the imaging setup in the garden, As I said, these have been fine, but the Altair is really messing with my mind. I'll re...

Hypercam 183c [fan cooled] cable query
I'm a bit bemused by this one. Recently bought a Hypercam 183c [fan cooled] camera from Altair, however the USB lead I'm trying to use cuts out at random intervals. this is the one i currently use with my Zwo183mc and SVBony 205 without any issue at all https://www.amazon.co.uk/LINDY-43098-Active-Ca...
