Just the 3 telescopes, a SW200p Dobbie, ST120 and a Evostar 120.

Small aperture APO for visual
Ian McCallum replied to SwiMatt's topic in Discussions - Scopes / Whole setups
Hopefully, I'm not too late to the discussion... I've got a couple of achros, specifically the SW ST120 and EV120. Both of these experience some for of CA, which I tend to filter with a Baader Fringe Killer filter (from memory). Before I got these, I was using a SW 200p Classic Dobbie. -
Night sky mental health boost for astronomy fan
Ian McCallum replied to FLO's topic in The Astro Lounge
My mum was in a lot of pain and was suffering from metastatic cancer, for nearly 18 months. She lingered in pain and it was cruel to see her like that, just wasting away. Palliative care was good, but not perfect. I had plenty of time to say goodbye to my mum and she had a good send off. My pony (Misty) took Colic one time, then another 2 bouts within 10 hours. She was in agony and suffering from gut death, it happened so fast that I had no choice but to have her euthanised. With Misty, I had planned to move her and my other pony to be with a friend's horses, but nature got in the way. She was rescued when I got her and was in very poor health. I had her 5 years and she was 21 years old when she died (not old for a Shetland). I feel that both her and I were cheated of many more years together! The regrets are very bitter, I can assure you. Your mileage will vary... -

Believe it or not, losing my pet was worse than losing my mum (2021). I was very close to my mum, but closer to my beloved pet. -

Would it work with VNC and a RPi? -
Night sky mental health boost for astronomy fan
Ian McCallum replied to FLO's topic in The Astro Lounge
I've not used a telescope in nearly a year, due to poor mental health. I lost a beloved pet on 5th February 2023, which caused me great anguish. For a long time, I couldn't get the loss out of my mind and still miss my beloved pet every day. I eventually tried to keep busy and concentrate on other hobbies. I've just set my astrophotography rig, for the first time in nearly 11 months. Obviously, I've missed out on nearly a year of things and have became very rusty - but hopefully, I'll get back into it again... PS: I've suffered from poor mental health for many years, but this was one of the worst bouts of it. -
Are light pollution filters still needed?
Ian McCallum replied to bendiddley's topic in Imaging - Discussion
That's disgusting!😠 -
There are laws against environmental, sound and air pollution - there should also be laws against gross light pollution. I'm sure there are already existing laws dealing with most of this stuff, but getting it enforced is a different matter.

I thought Demystifying Visual Astronomy was a guide on how to use dew heater straps on a Dob!😅 I'll get my coat...😜

I see the ASCOM driver update for the ASI120MM mini, but no firmware update other than v1.0. -
Isn't that a form of cognitive dissonance?
-
I'd try this... sudo apt update && sudo apt upgrade && sudo apt dist-upgrade

I've got VNC Viewer on my smartphone, so I should try that out more...
-
From what I've read, the focus wheels on my refractors can't be removed, therefore can't be fitted with the likes of the drive shaft type EAF.
-
It's the Evostar 120 achromat and the Startravel 120 achromat.
-
Yes, I can. I'd like an electric focuser, but there are none that I know of that would fit my telescopes.
-
I use the connection between my Raspberry Pi and laptop, so I've got a live FITS viewer on KStars and Okos, that allows me to see what's going on with the focus. I still have to go out and manually focus the telescope, then come back in to see what difference it's made...

Here at the two Bahtinov masks that I use, both bought from eBay. The small green one is a 3D printed one for the guide scope and the larger adjustable one is for either my Sky-Watcher Startravel 120 achromat or Evostar 120 achromat. I'm pretty that I had 'nailed' the focusing. Many thanks for confirming that. 👍
-
Just looking for some input, please. Does this image look like it's correctly focused using a Bahtinov mask for imaging? Please bare in mind that this is from an achromatic refractor, with only a single speed manual R&P focuser.

I've been using KStars and Ekos on my RPi for quite a while now, but have been getting large errors when it comes to coordinates for plate solving. I'm wondering if this is due to poor polar alignment? Can someone take a look at this log file, please and let me know what you think... I've removed my lat and long references from the log, for privacy reasons. log_18-40-54.txt

It's designed to stop scammers and rip-off merchants.

Try a Raspberry Pi loaded with Astroberry OS, as it supports INDI drivers for dome controls, etc.

I thought my browser wasn't loading images correctly, but it wasn't the problem. Posts can be edited later, to add photographs - I do that myself.
