Hi, i have made a video where i show a coople of eyepieces that i use and like, and also show how a barlow works, compared to the "Powermate" from Televue. And how is the FOV affected when changing the magnification with different eyepieces?
Feel free to comment and give me feedback - I hope you like the video!
I picked up a Celestron Omni last year quite cheaply and had originally been using that with stock eyepieces, which was fine.
Since then I've bought a couple of BST Starguiders and a Hyperflex zoom, and I'm now wondering if I'd notice any difference with a better barlow (this is now being used on an F/5 150mm Newtonian). Otherwise, the pennies can be directed elsewhere.
I'd not considered it before as the next rung up seemed to be around the £90-£100 mark, which seemed out of line with the rest of the spend. But I've seen some positive reviews of 3-element models in the region of £35-£40.
In particular, I've read good things about the Revelation/GSO Astro 2.5x (though apparently closer to 2.2x) and the Baader Classic Q 2.25x.
- does anyone have experience with both of these, and have a preference?
- would I notice any significant difference with either, compared with the Omni?
- I read somewhere that the Baader in particular required focussing the tube into the OTA to an extent that caused some image degradation. Obviously I'd want to avoid this if true, so is this a feature of the Baader, or of both, or of all (shorter?) barlows? (to be honest, I'd not thought to see whether this was happening with the Omni, I'll try to remember to check, if this weather ever breaks).
Thanks in advance.

I know it may be a bit of a long shot but I'm looking to buy a HEQ5 Pro mount or an NEQ6 Pro or something similar. Preferably belt driven but not necessary as can happily modify it. Please let me know if you have anything! Thanks.
Hi! I'm Fran
Not so long ago I took a picture of the ISS I never thought I was going to be able to get with the equipment I have.
After saving for a long time, I was able to buy my first scope, an OTA Skywatcher 200P. I adapted it to be used in a dobsonian base because it was the cheapest way I had to get it to work.
One night, I thought it might be cool to try to aim and record with my phone an ISS pass overhead. During the first attempt, I messed up the focus extremely bad but you can't imagine how happy I was to get a white blob in a frame that only I knew was the ISS.
The following afternoon I tried again. This time the flyby was almost exactly overhead and the night was crystal clear. So I manually tracked the station looking through the finder scope and recording it with my phone at 1080p 60fps. Without much expectations I downloaded the files into my computer to review them. And was shocked with the results.
The video was processed with PIPP, AutoStakkert and RegiStax.
If someone told me the image was taken with a phone and manually tracked with a shitty dobsonian base I would not believe him! I got really lucky that night, but I can not be happier with the results. I believe I got to the edge of what I can accomplish with the equipment that I was able to buy. I'm not sure if ext step up should be a real camera or a mount. Anyway, any of them are too expensive 😬
If you want to see the frames before processing (and some nice shots of the moon that night), I'll leave a link to the video where I show them:
Thank you so much for reading it all.
