Hi all, looking for some help please! 🙏 I have a wedge for my 8SE and when using EQ North to align it, it says it is slewing to Vega but ends up all the way over at Polaris!? Any ideas? 🤞🏻 Thanks in advance! 😊
I have updated the firmware, Mount is pointing at north, have inputted my latitude and longitude, I have tried picking the nearest city too and nothing seems to work! 😟
I have just bought a Celestron 18771-CGL power tank to allow me to get out to the dark skies of the South Downs with my Nexstar 8SE. This is a great bit of kit because it's so light and portable and powers the scope for hours no problem. However, I've also been thinking about getting a dew heater and the only downside of the power tank is it's lack of a second 12v output. I was looking on the First Light Optics website and they sell a DC splitter cable to allow two devices to be powered from a single output. I'm not an electrician obviously, but logical tells me if the dew heater controller is also a 12v device there should be no problem running both the scope and the heater at the same time other than draining the battery faster. Is anyone using a splitter cable in this way? Or can anyone confirm my logic is flawed?
Hi everyone I managed to wake up early this morning and get a great image processed using Registax6.1 of Uranus. I am new to astrophotography but enjoying every second of it. I have a Nexstar 4se that I used to capture these images with also increased my zoom by using a 2x Barlow. Only through my Neximage Burst Color (in which was used to take the images) was I able to make out to hazy blue planet best. Using iCap2.4 software for capturing the images heres what I did.....
- Images taken and processed September 4, 2019 around 5:00 A.M.- 5:30 A.M.
- decreased the gain to around 330-380 while exposure was set to 27 fps
- adjusted my focus
- took 200 frames at 25 fps
Continuing to Registax I processed the images only using the best frames out of 100, I added a few prefilters: BLUR was adjusted slightly to around 10-15, SMOOTH was decreased by around 5, and contrast prefilter, forget what it was called, was reduced to .90.
I tuned the wavelets until the hazy spot between the rings and planet were no longer visible and the difference with the rings and planet begin to appear. Here's the results hope they are as cool to everyone else, as I find it amazing my 4se can see that much into detail.
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.

Does anyone have any experience or knowledge about whether it's possible to mount alternative OTAs with a dovetail or rings to the mount that comes with a Celestron Nexstar 80GT? In particular I am wondering about attaching a SW Heritage 130P? I know that Celestron did a 130mm reflecting 'scope on his mount, but it looks to also have that plastic tube clamp, seen on the 80mm image below.
