Seems a bit ‘too good to be true’ Nigel but thanks for the info.

Again, thanks for the comments. We have just had a lengthy power cut in the area and although National Power Grid went out of their way to provide boiling water for hot drinks and a standby battery for the phone it would have been nice to have had a backup power source. So I was hoping to convince the wife that it would be money well spent. 😀

Thanks for the response.

As I cast around for a 12 volt PSU I wonder if any members are using the item above (or other models from that supplier) as until today I’ve never heard of them. Jackery and Bluetti seem to be regularly recommended but not the ECOFlow. Any comparisons would be appreciated. Thanks.

Probably an odd title but it's causing me a bit of a heartache. Any thoughts would be appreciated. I bought a s/h ZWO OAG-L with the intension of replacing my guide scope. What I did not realize before hand that that the OAG does not have a threaded aperture on on the camera side but it is designed to BOLT on to a filter wheel or direct to the camera. I do not have a filter wheel but I do have a single ZWO filter drawer which I want to place between the OAG and the camera. The only way that I can see is by using an adapter which ZWO make which is intended to replace a filter wheel. This adapter bolts on to the OAG and provides an M54 aperture, However it is 15mm wide and by the time the single filter drawer and the camera back focus have been added in such a distance would mean that the guide camera would ONLY JUST mount safely to equal the same distance. I wonder a) if the foregoing is understandable!! and b) if anyone has face a similar issue and come up with a solution. I should have also said that back focus is not of concern. Thanks, John

I upgraded from the HEQ5 (Rowan) to the EQ6-R but contrary to Clarkey I found an improvement in tracking. Of course this could be down to a number of things. Biggest downside for me was the weight as I am one of the many who must set up for each session. Carrying capacity is clearly significantly better.

Many thanks for the info. Pierre.

Just a quickie question. Is the new ZWO FF107 an ASKAR PHQ in disguise? The specs. seem very similar. Can anyone say?

Are the days of the GEM numbered in the light of recent ZWO announcement?

Again thanks for the contributions. Windjammer’s comment takes me back to my original comment about noticing the issue after a particularly windy session. I am one of the many who have to set up each evening. It went through my mind that something might have been loose but when it occurred in calm conditions I start to worry!! Hopefully, and in the light of members comments, I will be able to look again at the problem in the coming nights.

Thanks Olly. The ‘scope is 18 months old and I have never noticed the problem before the last three weeks. However I will recheck on a clear warmer evening if we get one!!

Thanks again. Post was deleted when I uploaded a TIF example. Not sure what the max file size is allowed. With regard to temperature the first time I noticed it was during a windy night but the temperature was well above freezing. I naively put the problem down to the wind!. I will however recheck the position of the dew heater.

Thanks for the response. The image is clipped to try and accentuate what I call a ‘bulge’. I’m not sure the system would cope with a large raw file

I wonder if there are any wise heads out there who could comment on a issue I have with star shape. I have an ZWO OSC camera attached to an Esprit 120 which is on an EQ6R-Pro controlled with a ZWO ASIAIR. The rig has been giving good results however over the last few nights I have noticed that the stars are no longer round and appear to have a slight 'bulge' to the circumference, Hopefully this is obvious in the attached image. This occurs with and without a filter in the light train. I recently fitted the ZWO EAF which seems to work well but I can't see that fitting the EAF would contribute to the issue. I have not yet had the opportunity to uncouple it to see if there is any difference but I thought I might get some sage thought from the forum in the mean time! All the stars exhibit the same 'bulging' no matter what position they appear in the image. Images are processed in PI. Any observations would be appreciated. Thanks.

Thanks Peter. The kit does seem to have been deleted. My usual approach is a gentle hand lift below the weights as I adjust the bolt.
