Mike, How did you get to use this telescope? Stewart Bean

Repeating this field on May 5th ( following my first observation on 28 April), Al Com is only just detectable with itelescope’s T14 106 mm refractor with a V filter. AstroImageJ gives an magnitude estimate of 15.0 but the S/N and S/B  are poor and the reference star is magnitude 11.9 – perhaps too bright to be the best choice.

However, using a Luminance filter it is still easily visible.

AL Com now at 14.34 as of 28 April. I used the T14 telescope in USA ( 100 mm refractor and cooled CCD) with a 300 s exposure , V filter, defocussed. AstroImageJ produced the estimate of magnitude. There are also a large number of galaxies close to M88/AL Com.
