I have a Skywatcher 200PDS. I managed to get images of saturn, jupiter with the telescope and the ASI120MC-S camera. However, to get a bit more magnified image of these planets I got myself a Barlow Tele Vue 3x and Revelation 5x. I am having trouble with this setup and really disappointed now. I am not able to achieve focus with any of these barlows using my planetary camera. I have added extension etc. but no luck whatsover. I just see a blank black video preview in SharpCap. I have seen people using the same setup and getting good images out of those. Any help highly appreciated.
Thanks and Regards,
I am unable to wind in the focus on my skywatcher 200 to achieve focus when a standard barlow is between tube and camera. I am seeking recommendations on a shorter version Barlow (with t ring) so that I can gain focus on Jupiter, Saturn on the camera. As far as I can see it would appear that longer barlows are around 5-6 inches and the shorter units are 2-3 inches. This reduced length would likely deliver the space I need to gain a focus.
Appreciate any advice on others who've no doubt overcome this issue.
