Computar 2.6mm F1.0 CCTV lens
This high quality ultra fast ultra wide angle CCTV lens is great for use with a highly sensitive CCTV camera for video recording meteors. These ultra fast lenses were discontinued by Computar several years ago and are now very rare. They originally sold for over $300 each.
Excellent condition. Lenses free from scratches and internal dust. DC auto iris tested and working.
£100 + £8 postage to UK mainland
2 x Computar HG0808 FCS-HSP ultra fast CCTV lenses
Very rare, high quality DC Auto iris CCTV lens designed for ultra-low light conditions. Ideally for use with CCTV cameras with a 1/2" chip, such as the Watec 902H2 series CCTV cameras.
Ideal for ultra low light conditions such as night time video capture of meteors. Both lenses in very good condition, with recently tested auto iris control, no scratches on glass and no fungus. One lens comes with original optional IR correction filter, but no front lens cap - £100
The other lens has no IR correction filter - £90
Postage £6.00 (insured and tracked)
a quick report of a bolide visible over Scotland last night (14th July 2019) at 23:02 local time. I was parked up in a garage forecourt to collect my son from back shift. The car was parked facing almost due north and I was looking towards the northern horizon for noctilucent clouds as the sky was so clear. The lat long location was at 55.7116, -3.8319.
The bolide appeared visible through the windscreen of the car. It was travelling a few degrees west of north and was large and relatively slow travelling for a meteor. It had an observable shape, being round and intensely bright, several magnitudes brighter than the nearly full moon behind me. It was yellow-orange with some hint of green at the margins. Towards the southern (lower) portion of the object there appeared to be a partial halo or arc that appeared to shimmer (much like a bright planet low to the horizon through a 'scope). At the tips of this arc there were streams of plasma following the object.
The sighting lasted perhaps a second at most before it dissipated in an intense flash. There was no fragmentation that I could see. I first observed it at around 25 degrees above the horizon and lost it at about 10 degrees. The angle of viewing meant it appeared to be heading almost straight "down" towards the horizon.
There was no sonic boom that I could hear, even though I had the window of the car wound down. There was passing traffic however, perhaps masking any low rumble.
This was very different to the "normal" meteors that one sees, even during the summer months when there are several showers and something that was quite unusual.
I've submitted a report to the UK MON this morning and it will be interesting to see if any other lucky amateur astronomers saw the object.
Hi there SGL
It is very long winded so sorry...
I am a complete newbie/beginner of astronomy. So you probably can all point out why I am wrong that I cannot see.
My wife bought me a Celestron nexstar 4se for Christmas that kick stared me on my long dormant interest in astronomy and the night sky.
I like the OTA and the simplicity of use but I found that I get more enjoyment of learning about the sky rather than just looking at something in the eyepiece that the magic fairy of GOTO bring up for me.
Also I found I learned more from finding alignment stars than using the GOTO function.
I am interested in taking photos of the objects with my M4/3 DSLR through the telescope, not to take the visually most pleasing images but to utilize the sensitivity of the sensor where my eyes fail me. (Hopefully training my eye will improve on that)
So more like EAA without the live aspect. I really don't mind waiting for 30-60 seconds for a photograph to expose and then loon at the details my eyes cannot record.
So that brings me to the question:
My funds are so limited that I need to make the changes from the price my 4se mount (ideally I would like to keep using the OTA after all it is a present...)
I found on eBay (I know now I am asking for it) an 8" Newtonian f4.5 (900mm) ON a manual Bresser exos-2 mount. For under £200
My primary interest is in the mount I know I will not be able to track for photography with it until a RA motor drive been fitted but I think I could learn the ropes with a manual then Mod the mount later (when funds allow it) maybe going for a full Onstep mod in the distant future.
What I read about this mount is that payload is 13 for visual and 7 for photography that is more than an eq5 so I can future proof myself a little. Also tracking meant to be good on this. Neq5, eq6, advanced vx, atlas are all out of the question as they are too expensive.
Is this mount suitable for my needs?
The 8" Newtonian is a noname "Astronomical Telescope" see below.
What my detective work points to is that this scope most likely is this:
It is parabolic and I cannot see anything fundamentally wrong with it.
I am hoping that this is a pre branded OK (not great) OTA that I can sell to cover some of the subsequent costs.
So should I buy this is this a good option?
sorry for the long winded post
And thank you
